Kootenai River White Sturgeon Investigation, 1994 Annual Report.
The U.S. Army Corps of Engineers in concordance with Bonneville Power Administration provided a release of 1.48 billion cubic meters (1.2 MAF, million acre feet) of impounded water from Lake Koocanusa, Montana from June 1 to June 28, 1994. This release of water provided approximately 566 To/s (20 thousand cubic feet per second, kcfs) discharge in the Kootenai River at Bonners Ferry, Idaho. Between February and early April 1994, 15 adult sturgeon (10 females, 5 males) in late vitellogenic stage were captured and fitted with combinations of radio and sonic transmitters. A total of 31 sturgeon were monitored. Ten hatchery reared juvenile white sturgeon equipped with radio and sonic tags were released in pools down river of Kootenai Falls, Montana. All ten sturgeon had moved between 60 and 97 km (37.3 and 60.3 mi) down river of release sites within one month. Movements coincided with major flow peaking associated with hydropower production at Libby Dam, located upriver of the release site
