The dam was completed in 1973 and was first filled in 1974, inundating the Kootenay River valley to form the 145 km long Koocanusa Reservoir (Lake Koocanusa). Canadian residents and water users are affected by changes in the Libby Dam operations that affect reservoir water levels, as nearly half (70 km) of the reservoir extends into southeastern British Columbia.

  • Spatial Distribution of Impacts to Channel Bed Mobility Due to Flow Regulation, Kootenai River, Usa
    SPATIAL DISTRIBUTION OF IMPACTS TO CHANNEL BED MOBILITY DUE TO FLOW REGULATION, KOOTENAI RIVER, USA Michael Burke1, Research Associate, University of Idaho ([email protected]); Klaus Jorde1, Professor, University of Idaho; John M. Buffington1,2, Research Geomorphologist, USDA Forest Service; Jeffrey H. Braatne3, Assistant Professor, University of Idaho; Rohan Benjankar1, Research Associate, University of Idaho. 1Center for Ecohydraulics Research, Boise, ID 2Rocky Mountain Research Station, Boise, ID 3College of Natural Resources, Moscow, ID Abstract The regulated hydrograph of the Kootenai River between Libby Dam and Kootenay Lake has altered the natural flow regime, resulting in a significant decrease in maximum flows (60% net reduction in median 1-day annual maximum, and 77%-84% net reductions in median monthly flows for the historic peak flow months of May and June, respectively). Other key hydrologic characteristics have also been affected, such as the timing of annual extremes, and the frequency and duration of flow pulses. Moreover, Libby Dam has impeded downstream delivery of sediment from the upper 23,300 km2 of a 50,000 km2 watershed. Since completion of the facility in 1974, observed impacts to downstream channel bed and bars in semi-confined and confined reaches of the Kootenai River have included coarsening of the active channel bed, homogenization of the channel bed, disappearance of relatively fine-grained beach bars, and invasion of bar surfaces by perennial vegetative species. These impacts have led to reduced aquatic habitat heterogeneity and reduced abundance of candidate recruitment sites for riparian tree species such as black cottonwood (Populus trichocarpa) and native willows (Salix spp.). Limited quantitative documentation of the pre-regulation substrate composition exists.

THE CANADA-UNITED STATES CONTROVERSY OVER THE COLUMBIA RIVERf RALPH W. JOHNSON* In a comprehensive study of the recent dispute between Canada and the United States over the Columbia River, Professor Johnson traces its history through the birth of the Harmon doctrine in 1898, the signing of the Boundary Waters Treaty in 1909, and the first Canadianclaim to downstream benefits in the early 1950's. Against this background, he analyzes the negotiations and events-particu- larly the Canadianproposals to divert the Columbia into the Fraser, and to develop the Peace River instead of the Columbia-that culmi- nated in the Columbia River Treaty in 1961. Before Canadian ratification of the Treaty, however, additional problems presented by the split between the Provincial and National governments had to be resolved. Their resolution brought about the signing of a Protocol with the United States in 1964, as well as ratification of the Treaty.

  • Changes in the Species Composition of the Fish Community in a Reach of the Kootenai River, Idaho, After Construction of Libby Dam Vaughn L
    Changes in the Species Composition of the Fish Community in a Reach of the Kootenai River, Idaho, after Construction of Libby Dam Vaughn L. Paragamian Idaho Department of Fish and Game 2750 Kathleen Avenue Coeur d'Alene, !D 83815 USA E-mail: [email protected] ABSTRACT I evaluated fish community structure and the density and growth of mountain whitefish (Prosopium williamsoni) downstream of Libby Dam in a 1.0-km reach of the Kootenai River, Idaho, in 1994 and compared the results with those of a similar study in 1980, after closure of the dam. In 1980 seven species of fish were collected; mountain whitefish comprised 70% of the sample (42% by weight), and largescale sucker (Catostomus macrocheilus) represented 19% of the sample (49% by weight). In 1994 of the eight species caught, mountain whitefish represented only 40% by number (19% by weight), and the largescale sucker was 65% of the sample (70% by weight). Growth of mountain whitefish was also slower in the early 1990s compared to the later 1970s. Reduced productivity because of the nutrient sink effect of Lake Koocanusa, river regulation, the lack of flushing flows, power peaking, and changes in river temperature may have led to the changes in the fish community structure. INTRODUCTION The aging process within reservoirs of the eastern USA is fairly well understood (Baxter 1977, Yurk and Ney 1989, Ney et al. 1990, Ney 1996); but less, is known of the process in reservoirs of the western USA and the main stem rivers downstream. Typically new reservoirs are not stable and are closer to riverine systems in productivity, but as they age the systems change because of nutrient binding in bottom sediments.

  • 1 International Kootenay Lake Board of Control 2018 Annual Report To
    International Kootenay Lake Board of Control 2018 Annual Report to the International Joint Commission This Annual Report covers the operations of Corra Linn Dam by the Applicant to the IJC Order (FortisBC) and the associated effects on the water level of Kootenay Lake in 2018. FortisBC operates Corra Linn Dam on the Kootenay River, approximately 22 kilometers upstream from its confluence with the Columbia River, and downstream from the West Arm of Kootenay Lake. FortisBC controls discharge through and around Corra Linn Dam in accordance with requirements of the Order of the International Joint Commission dated November 11, 1938. FortisBC co-operates with BC Hydro, which also manages a hydro-electric generating facility (the Kootenay Canal Project) which is hydraulically connected to the Corra Linn dam forebay on the Kootenay River through a constructed canal. Corra Linn Dam 1 Kootenay Lake 2018 Summary Throughout 2018, FortisBC operated Corra Linn Dam in a manner consistent with that prescribed by the 1938 Kootenay Lake Order. The minimum instantaneous water level was observed at 02:05:00 PDT on April 14th, 2018, at elevation 530.079 metres1 (1739.10 feet). Due to high lake inflow beyond the control of the Applicant, the lake level exceeded the IJC rule curve during the winter-spring drawdown period on March 17th, 2018, and the lake level did not reach the low elevation target of 530.145 metres (1739.32 feet) by the date required in the order (on or around April 1st). However, the Board determined that there was no violation of the IJC Order for Kootenay Lake because the Applicant responded by taking appropriate action of maintaining maximum flow through the natural flow constriction at Grohman Narrows, upstream of Corra Linn Dam.
