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.

Page 3: Introduction

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.

Page 5: Introduction

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.

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.

Page 9: Introduction

Accomplishments

• Pre- and Post Rodeo-Chedeski Data from Watershed and Reservoirs

Page 10: Introduction

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.

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

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.
