Comments:

Surveyed for 3 periods: spring migration, mid-breeding, and fall migration in 2004. Numbers here are just during mid-breeding season (June 9 to 16). Data is grouped by area and not broken down by lake/reservoir so some listed here may not be a breeding lake. Yonna Valley area includes Alkali Lake (surveyed by shore and air), Short Lake (surveyed by air), and Yonna Valley in general (surveyed by shore).
