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