Good stuff Sawtooth.

Looks like some of those mansion owners in the flood plains in Eagle need to get prepared.

February snow dump forces dam managers to raise Boise River again, to above flood stage
Quote:
The Boise Basin snowpack grew over the past month as mountain storms delivered 300 percent of normal February precipitation, forcing federal dam managers on the Boise River to prepare to raise the river above flood level with at least four months of runoff still ahead.

That means Treasure Valley residents should prepare for a long flooding season and consider buying flood insurance in low-lying areas. The basin’s snowpack was measured at 140 percent of average March 1, with the streamflow forecasts ranging from 150 percent to 190 percent of normal this year, reported the Idaho Natural Resources Conservation Service.

The U.S. Army Corps of Engineers reported Tuesday that 2.2 million acre-feet of water sits in the three Boise reservoirs and as snow in the mountains of the 2,680 square-mile watershed. That is despite increased flows below Lucky Peak since early February. The releases bought dam managers some capacity, with the three reservoirs at 52 percent, down from 61 percent a month ago.

Water managers from the Corps and the Bureau of Reclamation plan to raise the river to about 7,500 cubic feet per second by Friday. Flood stage is considered to be 7,000 cfs at the river gauge at the Glenwood Bridge in Garden City. Wednesday morning, the gauge showed about 7,200 cfs passing beneath the bridge — roughly 10 1/2 feet of water.
