BOISE, Idaho–To facilitate the completion of maintenance activities, the Bureau of Reclamation began reducing flows at Anderson Ranch Dam on Monday, July 29, 2019. By Thursday morning, August 1, 2019, the South Fork of the Boise River below Anderson Ranch Dam will be flowing at about 600 cubic feet per second.

“Managing our operations and maintenance program efficiently will aid in ensuring our infrastructure continues to perform as designed,” said Ryan Hedrick, Snake River Area Office hydrologist.

The reduction in flow is normal for this time of year, but the operation is occurring about 20 days early to allow for maintenance at Arrowrock Dam. A flow of 600 cfs will continue until mid-September. Flows will then be reduced to approximately 300 cfs, which is typical for the fall season.
