BOISE, Idaho – The Bureau of Reclamation and the U.S. Army Corps of Engineers plan an additional decrease in flow from Lucky Peak Dam by 250 cubic feet per second (cfs) Tuesday, June 13, 2017, at 10 am.
Rainfall over the past 24 hours in the city of Boise temporarily increased the flows at the Glenwood Bridge gauge overnight. As a result, the flows through the city of Boise are at approximately 8,800 cfs. The local inflows from the rain will continue to recede, and the decrease in discharges from Lucky Peak Dam will result in a flow of about 8,250 cfs this afternoon as measured at the Glenwood Bridge gauge.
The decrease in discharges from Lucky Peak is due to a decreasing trend in the long term forecasted inflows to the Boise system. The snowpack in the Boise basin is being depleted, and the current inflow forecast indicates that there is enough space available in the reservoir system to store the runoff. Further adjustments in flows could be necessary over the next week during this dynamic seasonal period.
A flow rate of 7,000 cfs is considered flood-stage level at the Glenwood Bridge gauge on the Boise River. The flow rate of 8,250 cfs is similar to the levels that occurred during mid-April.
Boise River reservoirs are at approximately 96 percent of capacity.
Residents of flood-prone areas in and near the greater-Boise area are encouraged to keep informed of changing river, stream, and weather conditions on the National Weather Service, Boise Office website at http://www.wrh.noaa.gov/boi/. The site offers flow data, weather forecasts, and flood alerts. Follow flood-response instructions issued by your local emergency management agency http://www.adacounty.id.gov/flood, and tune-in to local radio and television news stations. Ada County residents can sign up for CodeRED emergency alerts at https://public.coderedweb.com/cne/en-US/BF01DC4DD213, or download the CodeRED mobile app from your mobile device’s app store.

The Corps of Engineers and the Bureau of Reclamation operate three dams on the Boise River as a system to manage flood control and irrigation storage needs — Lucky Peak Dam, Arrowrock Dam and Anderson Ranch Dam. Storage capacity provided by Reclamation’s Arrowrock and Anderson Ranch dams, and the Corps’ Lucky Peak Dam, combined with well-planned water releases, help manage Boise River flows through the city of Boise.
