Introduction

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 everassembled.

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. 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. Algal Toxins

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

12. Multi-disciplinary Guest Speakers/Collaborators • Cheryl Pailzote, Hydrologist, White Mountain Apache Tribe – Effect of Rodeo-Chedeski Fire on Cultural and Natural Resources • Vince Lopes, UofA Watershed Dept.– Participatory Watershed Management. • Paul Sheppard, UofA Tree Ring Lab – Drought in the Southwest • Paul Gremillion, NAU – Paleolimnological Techniques in Reservoirs • Tim Kacerek, CAP – Release Strategies to Reduce T&O Complaints • Susan Fitch, ADEQ – Narrative Nutrient Criteria • Marc Dahlberg, AzG&F – Algal Toxins/Fish Kills • Ian Pepper, UA-WQC – Fund Leveraging • Clifton Bell, Malcolm-Pirnie – Narrative Nutrient Criteria • Fiona Jordan, UA, Microbiologist – Algal Toxins • Paul Zimba, USDA – Algal Toxins • JoAnn Burkholder, NCSU – Algal Toxins • Gregory Boyer, SUNY-CESF – Algal Toxins • Nikole Falls, ASU – Endocrine-Disrupting Compounds

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.
