Comments:

Surveyed for 3 periods: spring migration, mid-breeding, and fall migration in 2003. Numbers here are just during mid-breeding season (June 12 to 23). Data is grouped by area and not broken down by lake/reservoir so some listed here may not be a breeding lake. Gerber/Willow Valley watershed includes Alkali Spring, Antelope Reservoir, Big Adobe Reservoir, Boggs Lake, Bumphead Reservoir, Copeland Reservoir, De Vaul Lake, Dog Hollow Reservoir, and Dry Prairie.
