Sept. 29, 2016
Current Koocanusa Reservoir elevation: 2,445.1 feet
Current Koocanusa Reservoir inflow: ~5,000 cubic feet per second
Current Libby Dam outflow: 6,000 cfs
Current Kootenai River elevation at Bonners Ferry: 1,746.1 feet
Outflow from Libby Dam will remain at 6,000 cfs through Sept. 30. On Oct. 1, outflow will decrease over two hours to 5,000 cfs starting at 1 a.m. MST. On Oct. 2, the outflow will decrease further to 4,000 cfs starting at 1 a.m. MST.
The Northwest River Forecast Center creates daily forecasts for short term projections throughout the Kootenai and Columbia River Basins. These forecasts may be updated multiple times in a day and as conditions change. Links to those forecasts can be found below.
