Water managers at the U.S. Army Corps of Engineers, along with federal, tribal, and state fishery biologists, have determined that spring run-off conditions warrant the commencement of required flow augmentation at Libby Dam, Montana, for endangered Kootenai River white sturgeon downstream in Idaho. The flow augmentation operation includes increasing outflows to full powerhouse capacity for approximately two weeks to provide river conditions that may increase sturgeon spawning success in the lower Kootenai River.
