CVP Water Uses on Refuges

  • Irrigation of moist-soil plants
  • Flooded habitat
  • Food production
  • Decreased avian crowding

Exhibit GWD-3, p. 004

Wildlife Benefits of Refuge Water Use

  • Improved energetics
  • Increase in survival
  • Decrease in disease
  • Increased/stable populations

Potential Impacts of WaterFix Project

  • Habitat decline  decreased or unstable

avian populations

  • Reduced plant production  diminished

avian energetics and body condition

  • Reduced food supply and flooded habitat

 decreased survival and mating rates

  • Increased avian crowding  increased

instances of fatal avian disease outbreaks

  • Sandhill Crane
  • Black-necked Stilt
  • Peregrine Falcon
  • Loggerhead Shrike
  • Tri-colored Blackbird
