2. Introduction Data collection, analysis, and interpretation from all reservoirs and watersheds surrounding the Valley since 1999 makes this project the most comprehensive repository of information regarding conditions within all watersheds ever assembled.

3. Partnership with ADEQ Inter-agency service agreement means expanded opportunities for both the UA and ADEQ. Specifically trained (and occasionally audited) by ADEQ for data consistency, quality assurance and control. This pooling of resources allows optimal allocation of effort for both monitoring and research.

5. Partners/Sponsors/Collaborators in This or Previous Studies Arizona Game and Fish Dept. Central Arizona Project. Cities of Chandler, Mesa, Peoria, Phoenix, Scottsdale, and Tempe. Salt River Project. Tonto National Forest.

7. Analytes General chemistries Nutrients TOC/DOC Dissolved and total metals (sediment and aqueous) MIB/geosmin Perchlorate Physico-chemical Algal toxins (microcystin, anatoxin-a, cylindrospermopsin, saxitoxin) Chlorophyll a Algae counts and ID (periphyton and phytoplankton) Benthic macroinvertebrates Zooplankton

8. A Lot for a Little/Pooling of Resources ADEQ covering cost of most analyses since 2002. Latest sponsors: CAP and Peoria. Total project budget 2001-2004 was approximately $60,000/year.

9. Accomplishments Pre- and Post Rodeo-Chedeski Data from Watershed and Reservoirs

10. Algal Toxins The first to identify algal toxins in any of the reservoirs surrounding the Valley. Routine sampling for suites of toxins. Collaboration with both AzG&F and ADEQ to determine causes of recent fish kills in Salt River reservoirs.

11. Data Uses Ambient monitoring. Narrative nutrient criteria for Arizona lakes and reservoirs. Perchlorate task force. Impaired water identification (303(d) listing) Control of tastes and odors in the CAP

13. Mission Statements To inform resource management and regulatory agencies, utilities, and municipalities of long- and short-term trends in aquatic resources surrounding the Valley. To collect data and perform relevant research in a proactive and comprehensive, rather than piece-meal and reactive, manner.
