Middle Fork Boise River

Tributary of the Boise River

  • Recommended Fishing Water

Middle Fork Boise River in Elmore County is 72.6 miles in length.

This is a popular mountain river where anglers target a variety of salmonids within the mainstem and tributaries. Redband, bull trout, and whitefish are prized native sportfishes and may be caught readily. In addition, nonnative brook and cutthroat trout may be caught at times. This is a cold, relatively sterile river. Growth rates and maximum sizes are on the lower end of the spectrum, but catch rates can more than make up for it.
