BOISE, Idaho – The Bureau of Reclamation and the U.S. Army Corps of Engineers plan to keep discharge from Lucky Peak steady as runoff into the reservoir system increases with above normal temperatures. Boise River reservoirs are at approximately 85 percent of capacity. Flow through town is expected to decrease slightly as irrigation demand takes additional water from the river downstream of Lucky Peak Dam. Flow in the Boise River at Glenwood Bridge is estimated to fall to near 8,400 cfs by the end of today, based on the United States Geological Survey (USGS) rating table that was updated on May 17. The river will be back to levels seen during the first half of May.
Although recent warm temperatures have increased inflows to the reservoirs from snowmelt, reservoir managers do not currently anticipate a need to increase flows from Lucky Peak Dam based on current weather forecasts, increased irrigation demand, and remaining space in the reservoir system. However, future weather and snowmelt conditions could necessitate changes to this operation.
Flooding will continue to be a concern as flows remain high. Residents of flood-prone areas in and near Ada County 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.
