Boise River Continues To Rise As Reservoirs Are About 60%

Apr 11, 2019

The Boise river will be rising in the next few days as water managers react to recent spring rains.

Bureau of Reclamation engineer Chris Runyan says the river flow at the Glenwood bridge will be bumped up from the current 2,200 feet per second to 3,200 by Friday.

"We had a pretty large rain event and a lot of rain actually fell on the snow pack, so we went ahead and increased flows out of our system as well," Runyan says.

The Army Corps of Engineers and the Bureau of Reclamation share control of the Boise river system with the goal of managing river flows to prevent flooding, while leaving enough storage space behind the dams for runoff later this spring.

Reservoirs at Anderson, Arrowrock and Lucky Peak dams are now about 60% full. Runyan says the Boise river should remain at the 3,200-foot level for at least the next month, far below the near-record levels in the spring of 2017.
