South Fork Snake River Fishery

The South Fork of the Snake River provides outstanding angling opportunity, making it one of the most popular fisheries in Idaho.

The South Fork Snake River in eastern Idaho supports the largest river population of native Yellowstone cutthroat trout in Idaho as well as other popular game fish including Rainbow trout and Brown trout. The exceptional trout population and scenic beauty of the South Fork make it one of the finest fisheries in the country. Anglers are encouraged to harvest all rainbow trout they encounter here, as they can compete with native cutthroat.
