Description: This stretch of the Snake River is part of an Important Bird Area. The IBA contains some 126 bird species, hosts the largest breeding population of Bald Eagle in Idaho, and was rated the most unique and biodiverse ecosystem in Idaho by the U.S. Fish and Wildlife Service. The South Fork of the Snake River stretches some 60 miles from Palisades Dam to its confluence with the Henrys Fork. This area may be one of the last strongholds for the rare Yellow-billed Cuckoo in Idaho.
