Army Corps of Engineers: Small chance Boise River may increase to 10,000 cfs
BOISE, Idaho (KBOI) —
The Army Corps. of Engineers said Wednesday that there's a small chance that water managers may have to increase the Boise River to above 10,000 cfs.
Flows at that rate have only occurred two times in the past 100 years.
On Wednesday, local, state and federal officials joined Gov. Butch Otter to update the Treasure Valley on the ongoing threat of flooding along the Boise River after a historic winter that's caused $62 million in damages throughout state.
“I urge everyone to understand the dangers posed by floodwaters," Otter said. "Even when it looks shallow, the power of moving water can be deadly. "
In the Boise River Basin, the governor's office says "there is a small chance that Lucky Peak, Anderson Ranch and Arrow Rock reservoirs all could fill to capacity by the end of May. That likely would prompt increased flood-control releases downriver and exceptionally high flows through the cities of Boise, Garden City and Eagle."
On Sunday, the river measured at 8,840 cubic feet per second (11.09 feet) at the Glenwood Bridge in Garden City. Flood stage is 10.3 feet.
Local mayors relayed warning messages to the public and told stories about animals that have perished in the Boise River.
Tom Dale, former Nampa mayor and current Canyon County commissioner told of a story about a rancher who lost a bull that was washed away. And, earlier this month, a local resident lost her dog in the swift-moving current.
"If a bull can get washed a way, a kid can get washed away...," Dale said. "That river is powerful."
Also on Wednesday, Boise Police officers spent much of the day reminding local folks to stay off the Greenbelt.
