South Fork Boise will stay at 300 cfs until June

Good news for waders, bad new for boaters and campers, the South Fork will stay at winter flows, and it's restricted to day-use only from Anderson Ranch Dam to Danskin Bridge. 

The river reopens for fishing on Saturday, May 24, and it's a popular area for anglers and campers. Typically the river is flowing higher for the opener, but according to Melissa Jayo, spokesperson for the Bureau of Reclamation, the agency is keeping flows at 300 cfs until around June 1. 

Repairs need to be done on the dam outlet, she said, so the bureau is trying to fill the reservoir enough to allow water to go over the spillway. The reservoir needs to be at about 4,174 elevation to spill; it's currently at 4,167. Full pool is 4,196.

The bureau plans to increase flows to between 1,600 and 2,000 cfs around June 1, but that depends on whether the reservoir fills enough to run over the spillway by that date. 

Camping remains closed in the South Fork between Anderson Ranch Dam and Danskin Bridge due to last summer's wildfires in the area, as well as mudslides in the canyon in September. There are lots of dead trees in the area that could fall and other hazards, so the Forest Service is restricting it to day-use until further notice. 

Below Danskin Bridge is open, but low flows will make floating difficult, and the river may have downed logs and other debris. The Forest Service closure also means boaters also can not leave vehicles at the Danskin parking lot overnight because it's day use only.
