History of Protections for Central Valley Wetlands

1986 North American Waterfowl Management Plan  1989 Report on Water Supply Investigations  1990 Central Valley Joint Venture Implementation Plan  1992 Central Valley Project Improvement Act (CVPIA)

Exhibit GWD-3, p. 003

SLIDE 4

CVP Water Uses on Refuges

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

Exhibit GWD-3, p. 004

SLIDE 5

Wildlife Benefits of Refuge Water Use

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

SLIDE 9

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
