AVol.1 No.1 Arroyo replaces Water Resources News Bulletin as the name of the Water Resources Research Center's quarterly newsletter. A new name was chosen to go along with other recent changes to the newsletterexpanded coverage, enlarged mailing list, new format. We thank those who returned the questionnaire from the last issue since their suggestions provided help-fi. d ideas and insights as the newsletter was revised. Arroyo was chosen as a name be - cause it seems to fit a newsletter about ROYO New Name, Format For Newsieffer water iñ the arid Southwest. Water centers in other states have newsletters with such names as Water Current, Ripples and even Fresh Drops. Ob-viously, arid lands evoke a different type of water image. Arroyo conveys an image of water as it is known in Ari-zonauncertairi, infrequent, often inaccessible and occasionally coming down in a deluge to flow away in a flood. Arroyo will bring you water news from Arizona and the Southwest. Spring 1987 Arizona Department of Water Resources Developing Second Management Plan The continued funding of the Cen-tral Arizona Project depended upon Arizona implementing water con-servation measures in several critical areas in the state. Water consumption patterns in these Active Management Areas (AMAs) will be guided between 1980 and 2025 by a series of five man-agement plans to be developed by the Arizona Department of Water Re-sources (ADWR). ADWR is now in the final stages of preparing the Second Management Plan (SMP) which will be in effect be-tween 1990-2000. The Groundwater Code specifies that a plan for this period will be promulgated no later than January 1, 1988. The plans major objective is to achieve significant pro-gress toward safe yield (annual water withdrawal balanced by annual re-charge) for the Phoenix, Tucson, and Prescott AMAs. The plans also intend to maintain the agricultural economy of the Huai AMA, while ensuring ade-quate water supplies for future non-irrigation purposes in the region. The SMP will be prepared through a three-step process. Step one includes plan formulation, data collection, and WATER RESOURCES RESEARCH CENTER . UNIVERSITY OF ARIZONA i development of baseline studies of agri-cultural, municipal, and industrial water use patterns. Step two will con-centrate on developing conservation requirements for each use sector, and identifying conservation requirements for distribution systems. Also during step two, the ADWR will examine wa-ter augmentation options, including incentives for artificial groundwater re-charge. Finally, during this phase, ADWR, in cooperation with the Ari-zona Department of Health Services (and subsequenty the Arizona Depart-ment of Environmental Quality), will develop strategies to assess groundwa-ter qúality in the AMAs. The ADWR wifi prepare the actual plan document in step three. A series of planning committees and subcommittees have been developed to guide the plan preparation process. A Steering Committee (which includes the ADWR's Chief Deputy Director, Chief Counsel, Deputy Directors of En-gineering, Adjudication, and Administration and Water Manage-ment, as well as the four AMA Directors) is responsible to oversee the process to ensure that plans are consis-tent with legal requirements of the Groundwater Code and ADWR goals. A Plan Development Committee has also been formed to review work plans from five technical subcommittees; to iden-tify issues needing resolution; and to coordinate the planning process. The five technical subcommittees (con-cerned with agriculture, municipal and industrial uses, water resources, aug-mentation and reuse, and water quality) were developed to prepare the work programs for the SMP. The five technical subcommittees have made substantial progress de-veloping the work program elements. The Agricultural Conservation sub-committee has determined potentials for using effluent; determined conser-vation requirements for irrigation district distribution systems; developed and reviewed crop water requirements; identified characteristics of alternative irrigation systems; and determined areas of similar farming conditions and developed maximum conservation goals for each. The Municipal and Industrial sub-committee has collected water use data from large providers; identified al-ternative methods to achieve conservation; determined conservation potentials for each provider; and begun to develop programs to achieve conser-vation. The Water Augmentation and Reuse sub committee has developed a priority listing of augmentation sources for fur-ther study. Also, for each identified source, the subcommittee has con-ducted a literature search; collected data on water availability; and identi-fied potentials for direct use and/or water storage. The subcommittee has also begun an analysis of management strategies. The Water Resources subcommittee has developed baseline water budgets and has begun to develop scenario-generating strategies to identify the effects of various management alterna-tives on future water supplies. Finally, the Water Quality subcom-mittee is conducting a joint ADWR/ ADHS assessment of existing water quality. In addition, this subcommittee is examining ADWR's statutory au-thority under the Groundwater Code to identify the most effective ways for the department to integrate water quality considerations into the developing SMP. Prelimirary draft documents from the five technical subcommittees are anticipated to be completed by the end of July, 1987. These draft documents will then be reviewed by the Steering Committee, the Groundwater Users Ad-visory Councils (which are five-member boards created by the Ground-water Code to make recommendations on management programs and policies, and to provide comment and guidance to the AMA directors in the develop-ment of the management plans), and other public advisory bodies. The final draft of the Second Management Plan will be completed by October 1, 1987, and wifi be subject to review in formal public hearings to be held in each of the four AMAs during November. The Second Management Plan will then be promulgated on January 1, 1988. V INVITE D COMMENT ADWR Chief Outlines Plans, Progress Akin R Kleinman, director of the Arizona Department of Water Resources, contributed the invited comment. Dr. Kleinman, who took over as director in February, is a resource economist with 25 years of experience working with water resource issues in the West. Growing up on a Mesa, Arizona, dairy farm I had the opportunity to learn firsthand the critical role water supply problems play in economic survival. As a resource economist for the past 25 years, I have worked on water supply issues throughout the West. Now, as director of the Arizona Department of Water Resources, I face the challenging task of helping to ensure a dependable water supply for future generations. Luckily, the department has a very professional, dedicated staff to assist me in this task. Arizona's major water problem is the imbalance between the water consumed and the dependable supply. We currently rely on groundwater for over 60 pecent of our water supply. Arizonans annually consume approx imately 2 million acre-feet more groundwater than is replenished by nature. Arizona's water future will be more secure if we reduce mining of our groundwater supplies and reserve them for times of emergency, such as a prolonged drought. Many factors will contribute to our success in elm, mating groundwater overdraft, including completion of the Central Arizona Project, implementation of the 1980 Groundwater Management Qode, encouraging groundwater re - urge, and increasing our water supplies through effluent use, weather modification utilizing storm-water runoff and watershed management. The Central Arizona Project will be a tremendous help in solving our groundwater overdraft problem. The estimated long-term CAP water sup-ply is 1.2 million acre-feet annually-approximately two- thirds of the cur-rent rate of overdraft in central Arizona. The Department of Water Resources will continue to be a strong supporter of CAP and Plan 6 features of the project. I'd also like to expedite use of our full CAP water allocation. Arizona should be recharging as much CAP water as possible while we are waiting for municipal treatment plants and agricultural distribution systems to be completed. Arizona is fortunate to have the most comprehensive groundwater law «the nation. One of the primary ls of the Groúndwater Code is to control the severe overdraft of groundwater currently taking place in many parts of the state. The department's staff has done an excellent job of implementing the Groundwater Code over the last six and one -half years. Groundwater rights have been quantified; the first management plans have been adopted; work is well underway on the second management plans; and our enforcement program is in full swing. January 1, 1987, was the com-pliance date for the first mandatory conservation requirements in the Tucson, Phoenix and Prescott Active Management Areas. The department will be able to verify compliance when the 1987 pumpage reports are submitted. During this legislative session (1987) two bills were introduced in the Arizona Legislature (S.B. 1452 H. B. 2309) that would signifi-tantly impact the Groundwater Code. The department is opposed to most of the provisions of these bills, and I tes - tified so at a Joint Legislative Hearing. The Groundwater Code is not perfect, and each year the de-partment supports legislation that fine-tunes the Code. However, as di-rector of the Department of Water Resources, I could never support leg-islation that severely hampers the state's ability to achieve safe yield. While the Code strives to reduce groundwater use, the department is also assessing the potential for increasing Arizona's water supplies. Watershed management, weather modification, utilization of storm-water run-off and effluent use are all being studied. During the 1986 legislative session new groundwater recharge legislation was passed. Under this legislation the department is responsible for issuing permits, site inspection and record keeping for two types of projects. Re - charge Projects are designed to replenish groundwater aquifers, with no specific withdrawal rights for proj - ect sponsors. Storage and Recovery Projects store surplus water for fu-ture withdrawal by the project operator. In addition to these activities the department will also resume some long-range planning efforts. At the request of Governor Mecham we are working on a 50-year plan which will project future water supplies and demands. As you can see, many efforts are continuing to ensure that Arizona has a plentiful water supply for future generations. y .:;:: Aztec glyph of dry, sandy riverbed. LEGISLATIVE NEWS The new federal Water Quality Act be-came law on Feb. 4, 1987, not, however, before confronting some obstacles. The 99th Congress unanimously passed clean water legislation, but it was pocket-vetoed by the president. A new congress passed the same bill, and it again met with a presidential veto. Congress then overrode the veto. The new legislation amends and re-authorizes the Clean Water Act of 1972 (PL 92-500) which controls water pol-lution by establishing limits to wastewater discharges into lakes and streams. The 1987 amendments, however, also set up new initiatives, in-cluding a program to control pollution from non-point sources. This means rainfall runoff from farm and urban areas, construction, forestry and mm-ing sites and other diffuse or non-point sources will now be controled to limit pollution. Many see this as a needed new emphasis to the act which pre-viously focused on pollution from point sources; i. e., distinct sources such as industrial or municipal facilities. Non-point sources of pollution are emerging as a major concern since pol-lution from point sources is being reduced through regulatory actions. As a result, pollution from non-point sources now contribute a larger propor-tion to the natiorìs water quality problem. Estimates indicate that as much as 50 percent of the US. polluted water comes from non-point sources. Arizona non-point pollution comes from various sources. Agricultural runoff includes salts and nutrients from fertilizers as well as pesticides. Areas heavily grazed by cattle also contribute non-point pollution. Mining and industrial sites are believed to be sources of non-point pollution. Also, Arizonas limited surface water attracts intensive recreational use; the many boaters, swimmers and other visitors who visit Oak Creek Canyon, Lake Powell and the Chain of Lakes along the Salt River are sources of non-point pollution. The 1987 amendments contain the following provìsions to control non-point sources of pollution: Within 18 months each state is re-quired to submit a program for managing its non-point-source pollu-tion to the Environmental Protection Agency for approval. EPA will approve or disapprove pro-grams within 180 days. States whose programs are disapproved will be noti-fied of changes needed to gain approval. EPA will draw up programs within 30 months fór states that do not submit plans. Also, local agencies can draw up their own programs with EPA assistance. EPA is authorized to provide grants of up to 37.5 percent of the total cost to states to implement approved non-point source management programs. EPA is authorized to make similar grants to states having approved plans to carry out groundwater quality pro-tection projects with a federal share of up to 33.3 percent of the total cost. Although applauding the emphasis on non-point sources of pollution, some critics fault certain aspects of the act. Some complain that the amendments do not call for mandatory controls on non-point sources; instead, states are directed to conduct planning studies to look into such controls. Others are dis-appointed that a statutory program is not set up that would record early re-sults to determine later progress. Arizona is ahead of the federal gov-ernment and most other states in its concern with non-point sources of poi-lution. The state's Environmental Quality Act, which became effective last summer, establishes authority for control of pollution from non- point sources. ADHS is now working to draw up EQA regulations. Final regulations on non-point-source pollution are ex-pected to satisfy EPA's requirement that states have a program to control this threat to water quality. y RESEARCH Each issue of Arroyo presents brief de-scriptions of water research projects relevant to Arizona. Presented in this issue are abstracts of some of the pa-pers presented in the hydrology section at the 31st annual meeting of the Arizona-Nevada Academy of Sci-ence on April 18, at Northern Arizona University. The complete proceedings will be published this summer and will be available from the Arizona Section, American Water Resources Association, 845 North Park Avenue, Tucson, AZ 85719, c/o Dale Wright. Simulating the Impacts of Fire: A Hydrologic Component Peter F. Ffolliott William O. Rasmussen D. Phillip Guertin University of Arizona Tucson, AZ 85721 To aid land managers in estimating the impacts of fire on ponderosa pine forest ecosystems, a computer simulation model has been developed to obtain es-timates of benefits and losses after a fire on vegetative components, wildlife components, and hydrologic compo-nents. Regarding the hydrologic components, annual streamflow and changes in water quality, if any, are es-timated through analyses of time-trend response functions. For simulation pur-poses, the time-trend response functions are translated into an index of benefits or losses by initially deter-mining streams of annual ratio values. The technique also converts the flows of benefits or losses (that is, the streams of annual ratios) to annuities, or equal annual returns from the re-source. While annuities are normally thought of in terms of dollars, the con-cept is equally applicable to non-monetary flows such as annual stream-flow and changes in water quality. N E\iVS Predicting Solar Radiation From Cloud Cover For Snowmelt Modeling Douglas P. McAda and Peter E Ffolliott University of Arizona Tucson, AZ 85721 Much of the water in Arizona origi-nates as snowmelt runoff. Improvement of techniques to predict the amount and timing of snowmelt runoff may increase the efficiency by which this water can be used. To im-prove the prediction techniques, efforts have been made to model snowmeit processes through computer simula-tion. Most snowmelt models require measurement of solar radiation, a pri-mary source of energy for snowmelt. Unfortunately, direct measurement of solar radiation is not routinely avail-able. To estimate solar radiation from readily available information, equa-tions have been developed to predict daily direct and diffuse solar radiation from knowledge of opaque and trans-parent cloud cover. Through use of these equations, a watershed manage. can apply snowmelt computer simulas tion models to areas without direct measurement of solar radiation by using daily cloud cover information ob-tained by on-site observations. Flood Routing in Broad Ephemeral Stream Channels Carl Urikrich Hebert Osborn Agricultural Research Service United States Department of Agriculture Tucson, AZ Flood modeling in broad, sandy chan-nels is complicated by the presence of transient, meandering sub channels. A simple functional relationship between flow rate and channel cross- section geometry was incorporated into an ex-isting computer model (KINERSO). Both the original and altered versions were used to route seven flows betwe; measuring stations (Walnut Gulch, Ar zona). The bed abstraction component was adjusted to match simulated and observed peak flow rates. Simulated and observed total flow volumes were compared- The altered model reduced the error in volume by an average of 35 percent. Perhaps more significant, the optimal bed abstractions were much more reasonable. Analysis of Natural Ground-Water Level Variations for Aquifer Conceptualization Richard Nevulis Ross Wolford Donald R. Davis Soroosh Sorooshian University of Arizona Tucson, AZ 85721 Statistical evaluations of time-series groundwater data can be used to infer groundwater flow concepts. Advan-tages of such passive methods of analysis may include relative sim-plicity, low cost, and avoidance of disturbances typically associated with stress testing of aquifers. In this anal-ysis, selected statistical methods were tised to draw inferences on the charac-teristics of an aquifer within the Columbia River basalts in the Pasco Basin of south-central Washington. This information will be used in de-veloping a conceptual model of groundwater flow and in the planning of future hydrologic field investigations. Among the types of conceptual in-formation derived from statistical methods are time-series relationships between the basalt aquifer and the Co-lumbia River and the probable roles of structural deformations (primarily anticlinal folding) for providing impedi-ments to lateral groundwater movement. Hydrographs recorded in observation wells straddling a known subsurface hydrologic barrier trans-verse to the Cold Creek Syncline were correlated to determine the effective-ness of the barrier in isolating hydraulic stresses. The conceptualiza-tions derived from statistical analyses were, in several cases, able to be corn-bared with interpretations derived on the bases of subsequent stress re-sponses. A Seasonal Analysis of Colorado River Flows Through the Grand Canyon, Arizona, 1914-1984 Charles C Avery Stanley S. Beus S. W. Carothers Northern Arizona University Flagstaff, AZ 86011 Seasonal and periodic variations in Colorado River flows through the Grand Canyon regulate the biological/ riparian communities that have be-come established in the area. Fluctuating flows also have a marked effect on the existing beaches formed as river terrace deposits in the Grand Canyon. Both the above features are considered critical resources to recrea-tionists in the Grand Canyon. The timing and magnitude of reservoir re-leases as well as other aspects of river regulation are thus important consid-erations in recreational resource management and in total systems man-agement of the Colorado River. Glen Canyon Dam has controlled flows through Grand Canyon since 1962; this study presents monthly sta-tistical data for both pre- and post-dam periods and demonstrates the re-lation of the 1983, 1984 high water releases to the historic record. Water Quality of the Upper San Pedro Basin, Arizona Oralynn T. Self Arizona State University Tempe, AZ 85281 Due to rapid population growth, quality of the limited water resources of the Upper San Pedro Basin (USPB) in southeast Arizona has become a ma-jor concern. Available data shows water quality is generally good except for sev-eral localized problems. An area near St. David is now on the EPA's super-fund priority list. High nitrate concentrations make surface and groundwater unpalatable and poten-tially harmful to infants younger than three months old. Coliform concentra-tions are the most frequently violated state surface water quality standard in the USPB. Probable sources include oc-casional releases of raw sewage from a wastewater treatment plant in Naco, Mexico; runoff from grazing land; leaky septic tanks; and ineffective sewage treatment plants. Reports indi-cate continuing occasional minor releases of acidic, heavy metal polluted water from the Cananea mine opera-tions in Mexica Several major mine water releases occurred during the 1970s that seriously affected water quality of the San Pedro River killing all aquatic life along 60 miles of its length. Other USPB water quality is-sues include mine waste spills and leaks, rainwater contamination by smelter emissions, spills of hazardous material in transport, and potential contamination from pesticide applica-tions, landfills, and underground storage tanks. A Risk Analysis Approach to Ground-water Quality Management in the Upper Santa Cruz Basin T Richardson, Donald Davis University of Arizona Tucson, AZ 85721 Potential groundwater contaminant sources in the upper Santa Cruz basin that pose risks to human health in-dude copper mines, irrigated agriculture, and urban wastewater. Analysis of these risks provides useful information for comparing groundwa-ter quality management alternatives. Alternatives include preventing the in-put of contaminants at their sources, preventing migration of contaminants in groundwater to withdrawal points, and removal of contaminants at the points of groundwater withdrawal. The framework for risk analysis is com-posed of hazard identification, hazard evaluation, risk evaluation, and identi-fication of risk response alternatives. Potential contaminants identified range from inorganic ions to complex organic molecules. Hazards have been evaluated in terms of fate of potential contaminants in the environment and their toxicity. Risks to groundwater quality and human health in time and space are described with the use of a groundwater contaminant transport model. Because information for the analysis is incomplete, the evaluation of risks is not without uncertainties. Major uncertainties remain in data on contaminant concentrations and tox-icology of contaminants. RESOURCES AND IN FORMATION Arroyo will feature in each issue a re-source or source of information of interest to people concerned with wa-ter issues.

Full Text | AVol.1 No.1 Arroyo replaces Water Resources News Bulletin as the name of the Water Resources Research Center's quarterly newsletter. A new name was chosen to go along with other recent changes to the newsletterexpanded coverage, enlarged mailing list, new format. We thank those who returned the questionnaire from the last issue since their suggestions provided help-fi. d ideas and insights as the newsletter was revised. Arroyo was chosen as a name be - cause it seems to fit a newsletter about ROYO New Name, Format For Newsieffer water iñ the arid Southwest. Water centers in other states have newsletters with such names as Water Current, Ripples and even Fresh Drops. Ob-viously, arid lands evoke a different type of water image. Arroyo conveys an image of water as it is known in Ari-zonauncertairi, infrequent, often inaccessible and occasionally coming down in a deluge to flow away in a flood. Arroyo will bring you water news from Arizona and the Southwest. Spring 1987 Arizona Department of Water Resources Developing Second Management Plan The continued funding of the Cen-tral Arizona Project depended upon Arizona implementing water con-servation measures in several critical areas in the state. Water consumption patterns in these Active Management Areas (AMAs) will be guided between 1980 and 2025 by a series of five man-agement plans to be developed by the Arizona Department of Water Re-sources (ADWR). ADWR is now in the final stages of preparing the Second Management Plan (SMP) which will be in effect be-tween 1990-2000. The Groundwater Code specifies that a plan for this period will be promulgated no later than January 1, 1988. The plans major objective is to achieve significant pro-gress toward safe yield (annual water withdrawal balanced by annual re-charge) for the Phoenix, Tucson, and Prescott AMAs. The plans also intend to maintain the agricultural economy of the Huai AMA, while ensuring ade-quate water supplies for future non-irrigation purposes in the region. The SMP will be prepared through a three-step process. Step one includes plan formulation, data collection, and WATER RESOURCES RESEARCH CENTER . UNIVERSITY OF ARIZONA i development of baseline studies of agri-cultural, municipal, and industrial water use patterns. Step two will con-centrate on developing conservation requirements for each use sector, and identifying conservation requirements for distribution systems. Also during step two, the ADWR will examine wa-ter augmentation options, including incentives for artificial groundwater re-charge. Finally, during this phase, ADWR, in cooperation with the Ari-zona Department of Health Services (and subsequenty the Arizona Depart-ment of Environmental Quality), will develop strategies to assess groundwa-ter qúality in the AMAs. The ADWR wifi prepare the actual plan document in step three. A series of planning committees and subcommittees have been developed to guide the plan preparation process. A Steering Committee (which includes the ADWR's Chief Deputy Director, Chief Counsel, Deputy Directors of En-gineering, Adjudication, and Administration and Water Manage-ment, as well as the four AMA Directors) is responsible to oversee the process to ensure that plans are consis-tent with legal requirements of the Groundwater Code and ADWR goals. A Plan Development Committee has also been formed to review work plans from five technical subcommittees; to iden-tify issues needing resolution; and to coordinate the planning process. The five technical subcommittees (con-cerned with agriculture, municipal and industrial uses, water resources, aug-mentation and reuse, and water quality) were developed to prepare the work programs for the SMP. The five technical subcommittees have made substantial progress de-veloping the work program elements. The Agricultural Conservation sub-committee has determined potentials for using effluent; determined conser-vation requirements for irrigation district distribution systems; developed and reviewed crop water requirements; identified characteristics of alternative irrigation systems; and determined areas of similar farming conditions and developed maximum conservation goals for each. The Municipal and Industrial sub-committee has collected water use data from large providers; identified al-ternative methods to achieve conservation; determined conservation potentials for each provider; and begun to develop programs to achieve conser-vation. The Water Augmentation and Reuse sub committee has developed a priority listing of augmentation sources for fur-ther study. Also, for each identified source, the subcommittee has con-ducted a literature search; collected data on water availability; and identi-fied potentials for direct use and/or water storage. The subcommittee has also begun an analysis of management strategies. The Water Resources subcommittee has developed baseline water budgets and has begun to develop scenario-generating strategies to identify the effects of various management alterna-tives on future water supplies. Finally, the Water Quality subcom-mittee is conducting a joint ADWR/ ADHS assessment of existing water quality. In addition, this subcommittee is examining ADWR's statutory au-thority under the Groundwater Code to identify the most effective ways for the department to integrate water quality considerations into the developing SMP. Prelimirary draft documents from the five technical subcommittees are anticipated to be completed by the end of July, 1987. These draft documents will then be reviewed by the Steering Committee, the Groundwater Users Ad-visory Councils (which are five-member boards created by the Ground-water Code to make recommendations on management programs and policies, and to provide comment and guidance to the AMA directors in the develop-ment of the management plans), and other public advisory bodies. The final draft of the Second Management Plan will be completed by October 1, 1987, and wifi be subject to review in formal public hearings to be held in each of the four AMAs during November. The Second Management Plan will then be promulgated on January 1, 1988. V INVITE D COMMENT ADWR Chief Outlines Plans, Progress Akin R Kleinman, director of the Arizona Department of Water Resources, contributed the invited comment. Dr. Kleinman, who took over as director in February, is a resource economist with 25 years of experience working with water resource issues in the West. Growing up on a Mesa, Arizona, dairy farm I had the opportunity to learn firsthand the critical role water supply problems play in economic survival. As a resource economist for the past 25 years, I have worked on water supply issues throughout the West. Now, as director of the Arizona Department of Water Resources, I face the challenging task of helping to ensure a dependable water supply for future generations. Luckily, the department has a very professional, dedicated staff to assist me in this task. Arizona's major water problem is the imbalance between the water consumed and the dependable supply. We currently rely on groundwater for over 60 pecent of our water supply. Arizonans annually consume approx imately 2 million acre-feet more groundwater than is replenished by nature. Arizona's water future will be more secure if we reduce mining of our groundwater supplies and reserve them for times of emergency, such as a prolonged drought. Many factors will contribute to our success in elm, mating groundwater overdraft, including completion of the Central Arizona Project, implementation of the 1980 Groundwater Management Qode, encouraging groundwater re - urge, and increasing our water supplies through effluent use, weather modification utilizing storm-water runoff and watershed management. The Central Arizona Project will be a tremendous help in solving our groundwater overdraft problem. The estimated long-term CAP water sup-ply is 1.2 million acre-feet annually-approximately two- thirds of the cur-rent rate of overdraft in central Arizona. The Department of Water Resources will continue to be a strong supporter of CAP and Plan 6 features of the project. I'd also like to expedite use of our full CAP water allocation. Arizona should be recharging as much CAP water as possible while we are waiting for municipal treatment plants and agricultural distribution systems to be completed. Arizona is fortunate to have the most comprehensive groundwater law «the nation. One of the primary ls of the Groúndwater Code is to control the severe overdraft of groundwater currently taking place in many parts of the state. The department's staff has done an excellent job of implementing the Groundwater Code over the last six and one -half years. Groundwater rights have been quantified; the first management plans have been adopted; work is well underway on the second management plans; and our enforcement program is in full swing. January 1, 1987, was the com-pliance date for the first mandatory conservation requirements in the Tucson, Phoenix and Prescott Active Management Areas. The department will be able to verify compliance when the 1987 pumpage reports are submitted. During this legislative session (1987) two bills were introduced in the Arizona Legislature (S.B. 1452 H. B. 2309) that would signifi-tantly impact the Groundwater Code. The department is opposed to most of the provisions of these bills, and I tes - tified so at a Joint Legislative Hearing. The Groundwater Code is not perfect, and each year the de-partment supports legislation that fine-tunes the Code. However, as di-rector of the Department of Water Resources, I could never support leg-islation that severely hampers the state's ability to achieve safe yield. While the Code strives to reduce groundwater use, the department is also assessing the potential for increasing Arizona's water supplies. Watershed management, weather modification, utilization of storm-water run-off and effluent use are all being studied. During the 1986 legislative session new groundwater recharge legislation was passed. Under this legislation the department is responsible for issuing permits, site inspection and record keeping for two types of projects. Re - charge Projects are designed to replenish groundwater aquifers, with no specific withdrawal rights for proj - ect sponsors. Storage and Recovery Projects store surplus water for fu-ture withdrawal by the project operator. In addition to these activities the department will also resume some long-range planning efforts. At the request of Governor Mecham we are working on a 50-year plan which will project future water supplies and demands. As you can see, many efforts are continuing to ensure that Arizona has a plentiful water supply for future generations. y .:;:: Aztec glyph of dry, sandy riverbed. LEGISLATIVE NEWS The new federal Water Quality Act be-came law on Feb. 4, 1987, not, however, before confronting some obstacles. The 99th Congress unanimously passed clean water legislation, but it was pocket-vetoed by the president. A new congress passed the same bill, and it again met with a presidential veto. Congress then overrode the veto. The new legislation amends and re-authorizes the Clean Water Act of 1972 (PL 92-500) which controls water pol-lution by establishing limits to wastewater discharges into lakes and streams. The 1987 amendments, however, also set up new initiatives, in-cluding a program to control pollution from non-point sources. This means rainfall runoff from farm and urban areas, construction, forestry and mm-ing sites and other diffuse or non-point sources will now be controled to limit pollution. Many see this as a needed new emphasis to the act which pre-viously focused on pollution from point sources; i. e., distinct sources such as industrial or municipal facilities. Non-point sources of pollution are emerging as a major concern since pol-lution from point sources is being reduced through regulatory actions. As a result, pollution from non-point sources now contribute a larger propor-tion to the natiorìs water quality problem. Estimates indicate that as much as 50 percent of the US. polluted water comes from non-point sources. Arizona non-point pollution comes from various sources. Agricultural runoff includes salts and nutrients from fertilizers as well as pesticides. Areas heavily grazed by cattle also contribute non-point pollution. Mining and industrial sites are believed to be sources of non-point pollution. Also, Arizonas limited surface water attracts intensive recreational use; the many boaters, swimmers and other visitors who visit Oak Creek Canyon, Lake Powell and the Chain of Lakes along the Salt River are sources of non-point pollution. The 1987 amendments contain the following provìsions to control non-point sources of pollution: Within 18 months each state is re-quired to submit a program for managing its non-point-source pollu-tion to the Environmental Protection Agency for approval. EPA will approve or disapprove pro-grams within 180 days. States whose programs are disapproved will be noti-fied of changes needed to gain approval. EPA will draw up programs within 30 months fór states that do not submit plans. Also, local agencies can draw up their own programs with EPA assistance. EPA is authorized to provide grants of up to 37.5 percent of the total cost to states to implement approved non-point source management programs. EPA is authorized to make similar grants to states having approved plans to carry out groundwater quality pro-tection projects with a federal share of up to 33.3 percent of the total cost. Although applauding the emphasis on non-point sources of pollution, some critics fault certain aspects of the act. Some complain that the amendments do not call for mandatory controls on non-point sources; instead, states are directed to conduct planning studies to look into such controls. Others are dis-appointed that a statutory program is not set up that would record early re-sults to determine later progress. Arizona is ahead of the federal gov-ernment and most other states in its concern with non-point sources of poi-lution. The state's Environmental Quality Act, which became effective last summer, establishes authority for control of pollution from non- point sources. ADHS is now working to draw up EQA regulations. Final regulations on non-point-source pollution are ex-pected to satisfy EPA's requirement that states have a program to control this threat to water quality. y RESEARCH Each issue of Arroyo presents brief de-scriptions of water research projects relevant to Arizona. Presented in this issue are abstracts of some of the pa-pers presented in the hydrology section at the 31st annual meeting of the Arizona-Nevada Academy of Sci-ence on April 18, at Northern Arizona University. The complete proceedings will be published this summer and will be available from the Arizona Section, American Water Resources Association, 845 North Park Avenue, Tucson, AZ 85719, c/o Dale Wright. Simulating the Impacts of Fire: A Hydrologic Component Peter F. Ffolliott William O. Rasmussen D. Phillip Guertin University of Arizona Tucson, AZ 85721 To aid land managers in estimating the impacts of fire on ponderosa pine forest ecosystems, a computer simulation model has been developed to obtain es-timates of benefits and losses after a fire on vegetative components, wildlife components, and hydrologic compo-nents. Regarding the hydrologic components, annual streamflow and changes in water quality, if any, are es-timated through analyses of time-trend response functions. For simulation pur-poses, the time-trend response functions are translated into an index of benefits or losses by initially deter-mining streams of annual ratio values. The technique also converts the flows of benefits or losses (that is, the streams of annual ratios) to annuities, or equal annual returns from the re-source. While annuities are normally thought of in terms of dollars, the con-cept is equally applicable to non-monetary flows such as annual stream-flow and changes in water quality. N E\iVS Predicting Solar Radiation From Cloud Cover For Snowmelt Modeling Douglas P. McAda and Peter E Ffolliott University of Arizona Tucson, AZ 85721 Much of the water in Arizona origi-nates as snowmelt runoff. Improvement of techniques to predict the amount and timing of snowmelt runoff may increase the efficiency by which this water can be used. To im-prove the prediction techniques, efforts have been made to model snowmeit processes through computer simula-tion. Most snowmelt models require measurement of solar radiation, a pri-mary source of energy for snowmelt. Unfortunately, direct measurement of solar radiation is not routinely avail-able. To estimate solar radiation from readily available information, equa-tions have been developed to predict daily direct and diffuse solar radiation from knowledge of opaque and trans-parent cloud cover. Through use of these equations, a watershed manage. can apply snowmelt computer simulas tion models to areas without direct measurement of solar radiation by using daily cloud cover information ob-tained by on-site observations. Flood Routing in Broad Ephemeral Stream Channels Carl Urikrich Hebert Osborn Agricultural Research Service United States Department of Agriculture Tucson, AZ Flood modeling in broad, sandy chan-nels is complicated by the presence of transient, meandering sub channels. A simple functional relationship between flow rate and channel cross- section geometry was incorporated into an ex-isting computer model (KINERSO). Both the original and altered versions were used to route seven flows betwe; measuring stations (Walnut Gulch, Ar zona). The bed abstraction component was adjusted to match simulated and observed peak flow rates. Simulated and observed total flow volumes were compared- The altered model reduced the error in volume by an average of 35 percent. Perhaps more significant, the optimal bed abstractions were much more reasonable. Analysis of Natural Ground-Water Level Variations for Aquifer Conceptualization Richard Nevulis Ross Wolford Donald R. Davis Soroosh Sorooshian University of Arizona Tucson, AZ 85721 Statistical evaluations of time-series groundwater data can be used to infer groundwater flow concepts. Advan-tages of such passive methods of analysis may include relative sim-plicity, low cost, and avoidance of disturbances typically associated with stress testing of aquifers. In this anal-ysis, selected statistical methods were tised to draw inferences on the charac-teristics of an aquifer within the Columbia River basalts in the Pasco Basin of south-central Washington. This information will be used in de-veloping a conceptual model of groundwater flow and in the planning of future hydrologic field investigations. Among the types of conceptual in-formation derived from statistical methods are time-series relationships between the basalt aquifer and the Co-lumbia River and the probable roles of structural deformations (primarily anticlinal folding) for providing impedi-ments to lateral groundwater movement. Hydrographs recorded in observation wells straddling a known subsurface hydrologic barrier trans-verse to the Cold Creek Syncline were correlated to determine the effective-ness of the barrier in isolating hydraulic stresses. The conceptualiza-tions derived from statistical analyses were, in several cases, able to be corn-bared with interpretations derived on the bases of subsequent stress re-sponses. A Seasonal Analysis of Colorado River Flows Through the Grand Canyon, Arizona, 1914-1984 Charles C Avery Stanley S. Beus S. W. Carothers Northern Arizona University Flagstaff, AZ 86011 Seasonal and periodic variations in Colorado River flows through the Grand Canyon regulate the biological/ riparian communities that have be-come established in the area. Fluctuating flows also have a marked effect on the existing beaches formed as river terrace deposits in the Grand Canyon. Both the above features are considered critical resources to recrea-tionists in the Grand Canyon. The timing and magnitude of reservoir re-leases as well as other aspects of river regulation are thus important consid-erations in recreational resource management and in total systems man-agement of the Colorado River. Glen Canyon Dam has controlled flows through Grand Canyon since 1962; this study presents monthly sta-tistical data for both pre- and post-dam periods and demonstrates the re-lation of the 1983, 1984 high water releases to the historic record. Water Quality of the Upper San Pedro Basin, Arizona Oralynn T. Self Arizona State University Tempe, AZ 85281 Due to rapid population growth, quality of the limited water resources of the Upper San Pedro Basin (USPB) in southeast Arizona has become a ma-jor concern. Available data shows water quality is generally good except for sev-eral localized problems. An area near St. David is now on the EPA's super-fund priority list. High nitrate concentrations make surface and groundwater unpalatable and poten-tially harmful to infants younger than three months old. Coliform concentra-tions are the most frequently violated state surface water quality standard in the USPB. Probable sources include oc-casional releases of raw sewage from a wastewater treatment plant in Naco, Mexico; runoff from grazing land; leaky septic tanks; and ineffective sewage treatment plants. Reports indi-cate continuing occasional minor releases of acidic, heavy metal polluted water from the Cananea mine opera-tions in Mexica Several major mine water releases occurred during the 1970s that seriously affected water quality of the San Pedro River killing all aquatic life along 60 miles of its length. Other USPB water quality is-sues include mine waste spills and leaks, rainwater contamination by smelter emissions, spills of hazardous material in transport, and potential contamination from pesticide applica-tions, landfills, and underground storage tanks. A Risk Analysis Approach to Ground-water Quality Management in the Upper Santa Cruz Basin T Richardson, Donald Davis University of Arizona Tucson, AZ 85721 Potential groundwater contaminant sources in the upper Santa Cruz basin that pose risks to human health in-dude copper mines, irrigated agriculture, and urban wastewater. Analysis of these risks provides useful information for comparing groundwa-ter quality management alternatives. Alternatives include preventing the in-put of contaminants at their sources, preventing migration of contaminants in groundwater to withdrawal points, and removal of contaminants at the points of groundwater withdrawal. The framework for risk analysis is com-posed of hazard identification, hazard evaluation, risk evaluation, and identi-fication of risk response alternatives. Potential contaminants identified range from inorganic ions to complex organic molecules. Hazards have been evaluated in terms of fate of potential contaminants in the environment and their toxicity. Risks to groundwater quality and human health in time and space are described with the use of a groundwater contaminant transport model. Because information for the analysis is incomplete, the evaluation of risks is not without uncertainties. Major uncertainties remain in data on contaminant concentrations and tox-icology of contaminants. RESOURCES AND IN FORMATION Arroyo will feature in each issue a re-source or source of information of interest to people concerned with wa-ter issues.
