  1. ANS & IPM in the Central Arizona and Salt River Projects Major conduit of ANS Critical partners in IPM

  2. CAP and SRP are major aquatic resources in Arizona • Include over 800 km of major aqueduct • Includes over 1,000 km of minor canals • CAP includes Lake Pleasant • SRP includes Roosevelt, Apache, Canyon, Saguaro, Horseshoe, and Bartlett Lakes

  3. Stakeholders • Governments • Urban water users • Farmers • Developers • Aquatic recreation • Fish and wildlife

  4. CAP ANS Issues • Source water from the Colorado River • Transport of exotic fishes, bivalves, aquatic weeds • Year-round water movement

  5. SRP ANS Issues • Source water from the Bradshaw and White Mountains • Multiple recreation lakes in close proximity to metro area • Transport of exotic fishes, bivalves, aquatic weeds • Year-round water movement

  6. ANS Management implicationsfor operations • Aquatic weeds impede flow • Concern over introduction of Zebra mussels and other bivalves • Taste and odor problems for potable water • Deposition of sediments

  7. Traditional methods of management • Algae and weeds - chemicals and physical • Exotic bivalves - molluscides • Taste and odor algae - chemicals and carbon filtration • Bar grates for large fish

  8. Integrated PestManagement • Education • Exclusion • Monitoring • Control • Eradication?

  9. Integrated PestManagement - Education • Operating Staff • Management • Recreation public • Other stakeholders

  10. Integrated PestManagement - Exclusion • Work with Task Force to avoid introduction • Control structures at inflow • Recreation public • Other stakeholders

  11. Integrated PestManagement - Monitoring • Collectors • Staff inspections • SCUBA inspections • Remote sensing • Other agencies staff and public

  12. Integrated PestManagement - Control • Algae and weeds - triploid grass carp • Exotic bivalves - triploid bighead carp? • Aquatic weeds - nutrient management • Dry down • Chemicals

  13. Additional Integrated PestManagement - Control • Watershed monitoring -(Colorado Basin, Salt River, Bill Williams River) • Limit transport of exotics - aquaculture, recreation • Use of water for recharge - basins ideal for exotic plants

  14. Future Management Issues • Further reduction in irrigation and more urban supply - better water quality • Large amounts for recharge projects - need to avoid plugging • Require more input to watershed management • Protection of native fish, control of exotics
