Boise River Greenbelt Flood Warning: River Flows Set to Increase Today
More flooding along the Boise Greenbelt could be seen over the Memorial day weekend as the U.S. Army Corps of Engineers and the Bureau of Reclamation are increasing flows from Lucky Peak Dam by 1,000 cubic feet per second (cfs) today (5/25)
Flows through Boise, as measured at the Glenwood Bridge gauge, will increase to approximately 6,500 cfs by Friday afternoon. The increase in flows is because of continued wet conditions forecasted for the coming week, especially in the mountain.
Treasure Valley residents can expect more changes in future flows through the Boise area as reservoir managers continue to operate the reservoir system for flood risk management.
A flow rate of approximately 7,000 cfs is considered flood-stage level. At 6,500 cfs, large sections of the Greenbelt path adjacent to the river will be submerged and minor flooding may be observed in portions of Eagle Island.
According to the US Army Corps of Engineers, the Boise River reservoirs are at approximately 98 percent of capacity. As the flood risk subsides in the coming weeks, Lucky Peak Reservoir will be filled to the normal summer operating level to accommodate recreational opportunities. A full supply of irrigation water is anticipated this summer.
Officials advise 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.
