BOISE, Idaho – The Bureau of Reclamation and the U.S. Army Corps of Engineers will again increase flows from Lucky Peak Dam on Friday, June 2, at 8 am. These increases are in addition to those changes completed earlier today and are necessary because of rapidly changing weather and runoff conditions.
Flows through the city of Boise will increase another 500 cubic feet per second (cfs) Friday morning, resulting in a flow of approximately 9,300 cfs at the Glenwood Bridge gauge. Boise River reservoirs are at approximately 90 percent of capacity. Further increases could be necessary over the next week during this active snowmelt 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 9,300 cfs will be the highest levels that have occurred this spring. At 9,500 cfs, additional sections of the Boise Greenbelt adjacent to the river will be submerged, and erosion of river banks will continue to be a significant problem. Flooding will continue to occur in areas in Eagle Island, Garden City, Star, and Caldwell. Water will cover portions of the Warm Springs Golf Course and Municipal Park in east Boise. The water may affect some residential property near the river but should stay below the level of most residential structures. The river will spill over its banks between 45th and 47th streets in Garden City into the warehouse district. Floating debris could become a problem if large quantities collect on bridges, impacting river flows.
