The Bureau of Reclamation and the U.S. Army Corps of Engineers will continue to increase flows through town. Currently, flows through town are 1,760 cubic-feet-per-second (cfs) and will stay at this rate through the weekend. Flows through town will increase by 500 cfs on Monday and on Tuesday, March 26-27, 2018. On Wednesday, March 28, 2018, flows through town will increase by an additional 200 cfs to approximately 3,000 cfs.

These increases are due to snowpack rising from 66 to 89 percent of the median value for the Boise basin. Precipitation in the basin has been above average for the month of March. The releases will help reduce the risk of flooding later in the spring, which can happen with rapidly melting snow and seasonal precipitation. Additional flow increases are possible in the coming weeks depending upon weather conditions.

Currently, the Boise River reservoirs are at approximately 84 percent of capacity. A full supply of irrigation water is anticipated this summer.

Officials are advising the public to be aware of the danger associated with increased Boise River flows. The water is deep, cold, and fast. Extreme caution should be used near the river banks.
