Snake River (South Fork Snake River)

Tributary of the Snake River

  • Recommended Fishing Water

Snake River (South Fork Snake River) in Bonneville, Jefferson and Madison Counties is 128.9 miles in length.

The South Fork is widely regarded as one of the finest trout fishing rivers in the country. It's home to native Yellowstone cutthroat trout, which are noted as very willing to take a dry fly. The river also houses rainbow trout and brown trout. Anglers are encouraged to harvest all rainbow trout they encounter here, as they can compete with native cutthroat.

In this video, Trapper Bradshaw shares taking his son Hunter out for a day of float boat fishing on the South Fork of the Snake River. A perfect outdoor adventure for father and son.
