From the confluence of the Snake and Clearwater Rivers, this IBA stretches along the rivers for 5 miles in each direction.

Ornithological Summary

This site is important for its high concentration of wintering waterfowl, with 4,000-8,000 ducks and 500-2,000 geese each year. Regularly occurring waterfowl include Mallard, American Wigeon, Northern Pintail, Wood Duck, Scaup sp., Ring-necked Duck, American and Barrow?s Goldeneye, Bufflehead, Common Merganser, Long-tailed Duck, and Canada Goose. The concentration of Barrow's Goldeneyes, averaging well over 1,500 birds, may be the largest interior wintering population for this species.

Conservation Issues

Disturbance of birds is a minor problem in this area, although the confluence is currently protected by a hunting ban. There are also likely issues with water pollution, as well as potential problems with recreational overuse and residential/commercial development. However, no significant issues have been identified at this time.

Habitat
