Kootenay System Operations
Columbia River Treaty Review – Technical Studies Appendix C Kootenay System Operations Operation of the Kootenay River system is complicated as it is administered by several different jurisdictions and the hydroelectric facilities are owned by different agencies/companies. As shown in Figure 1, the Kootenay River originates in the Rocky Mountains not far from Field, BC. The river flows south, within a few km of the source of the Columbia River at Canal Flats, and then continues south into Koocanusa Reservoir, formed behind Libby Dam in Montana, United States. From Libby, the Kootenay River turns west and north, and re-enters British Columbia near the community of Creston, flowing into the south arm of Kootenay Lake. In the northern part of the Kootenay basin, the Duncan River is joined by the Lardeau River just downstream from Duncan Dam, and then flows into the north arm of Kootenay Lake. Water from the north and south arms of Kootenay Lake then flows through the west arm of the lake and past the Corra Linn Dam near Nelson (as well as other dams) en route to the Columbia–Kootenay confluence at Castlegar. The components of this system and various agreements/orders that regulate flows are described in this Appendix.

The Scoping Study is guided by the Brilliant Headpond Stewardship Initiative Steering Committee, which includes leaders from the Brilliant Headpond communities of Tarrys, Thrums, Glade, Shoreacres, and South Slocan, representatives of the Ktunaxa First Nation and Okanagan Nation Alliance, and Regional District of Central Kootenay (RDCK) Area I Director, Andy Davidoff, and RDCK Area H Director, Walter Popoff. The Brilliant Headpond Reservoir (“BHPR”) was created by the damming of the Kootenay River at the Brilliant Canyon for the completion of the West Kootenay Power Corps. Brilliant Dam hydroelectric project completed in 1944. The BHPR area extends from Columbia Power Corporation’s (current owner) Brilliant Dam and Brilliant Expansion Project (2007) upstream to the Slocan Pool area just below BC Hydro’s Kootenay Canal (1975) and FortisBC’s South Slocan (1928) dams. FortisBC owns and operates the four dams on the Lower Kootenay, upstream of Brilliant Dam, and FortisBC operates Brilliant Dam and Brilliant Expansion facilities on behalf of Columbia Power Corporation.

International Kootenay Lake Board of Control
International Kootenay Lake Board of Control 2007 Annual Report to the International Joint Commission Grohman Narrows Viewed looking downstream from high above the City of Nelson, BC, Grohman Narrows (centre) throttles the West Arm of Kootenay Lake into the lower Kootenay River. The feature was named after William Adolph US Section: Baillie-Grohman, who, late in the 19th century, attempted to deepen the 4735 East Marginal Way South narrows in an early effort to reclaim the farmlands of the Creston Valley Seattle, Washington 98134-2385 U.S.A. and Kootenai Flats. With his attempt no match for river bed, the narrows remained relatively intact until the West Kootenay Power and Light Canadian Section: 201 – 401 Burrard Street Company dredged the constriction as a condition of the International Joint Vancouver, BC V6C 3S5 Commission’s 1938 Order for Kootenay Lake. For more information on Bill Canada Grohman, see the BC Historical Quarterly, Vol. XX, 1956. 1 Kootenay Lake 2007 Summary In general, throughout 2007, FortisBC regulated the level of Kootenay Lake below the maximum limits prescribed by the 1938 Kootenay Lake Order. However, for a considerable period prior to spring rise, the lake level exceeded the prescribed limit primarily due to extraordinary natural high inflow conditions. The maximum instantaneous water level for the lake at Queens Bay was observed at 07:00 PST on June 7th at elevation 533.481 metres1 (1750.27 feet). The minimum instantaneous water level was observed at 02:05 PST on March 12th at elevation 530.435 metres (1740.27 feet). Kootenay Lake discharged 25.5 cubic kilometres (20.7 million acre- feet) of water in 2007, with an average flow of 810 cubic metres per second (28,600 cubic feet per second).

Grohman Narrows Channel Improvement Project
GROHMAN NARROWS CHANNEL IMPROVEMENT PROJECT 12 Sept 2013 1 BACKGROUND AND PROJECT DRIVERS • Grohman Narrows is a natural hydraulic constriction on the Kootenay River, ~3 km downstream of Nelson • The constriction is primarily due to a naturally high river bed elevation through the reach • The river narrows to an approximate width of 175 m at the upstream end of the reach • Bed elevation through the reach varies between approximately El. 520 m (1706 ft) and El. 530 m (1739 ft). BACKGROUND AND PROJECT DRIVERS • The effects of the Grohman Narrows constriction include: • Higher peak flood levels on Kootenay Lake • Reduced ability to release water from Kootenay Lake, especially from March to June, to fully utilize the storage flexibility of the lake • Reduced head and generation at Corra Linn and Kootenay Canal and increased spill at Corra Linn and all of the downstream Kootenay River dams • Less operating flexibility at Kootenay Canal, Corra Linn, and the downstream Kootenay River plants • Channel improvements at Grohman Narrows would improve all these effects • In response to local government and community concerns, BC Hydro initiated the project to explore potential improvements to Grohman Narrows in late 2012 PROJECT AREA 4 PREVIOUS EXCAVATION EFFORTS • The benefits of channel improvements in the Grohman Narrows have been recognized since the 1890’s. 1890: • An estimated 18,000 cubic yards of blasted rock, boulder and gravel removed from the riverbed 1931: • Approximately 350,000 m3 of rock and 200,000 m3 of boulders and gravel • Material

Columbia River Treaty Frequently Asked Questions (Faqs) Spring 2012
Columbia River Treaty Frequently Asked Questions (FAQs) Spring 2012 Columbia River Treaty 1. What is the Columbia River Treaty? The Columbia River Treaty is a trans-boundary water management agreement between the United States and Canada signed in 1961 and ratified in 1964. The Treaty optimizes flood management and power generation, requiring coordinated operations of reservoirs and water flows for the Columbia River and Kootenay River on both sides of the border. It does not have a specified end date, however, the Treaty can be terminated on or after September 16, 2024 provided that either Canada or the United States has given at least 10 years notice of their intention to terminate. 2. What are the Canadian and U.S. Entities The U.S. Entity is made up of the Bonneville Power Administration and the United States Army Corps of Engineers. The Canadian Entity is BC Hydro. The Columbia River Treaty is implemented by the entities. Together, they work cooperatively and are responsible for the daily operations of the reservoirs and hydroelectric facilities. The Province of British Columbia is the Canadian Entity to manage the Canadian Entitlement, Canada’s half share of the downstream power benefits. 3. What are the benefits to British Columbia from the Columbia River Treaty? The Columbia River Treaty has brought significant flood control and power benefits to British Columbia. at-site electricity generation • Mica dam and Arrow Lakes Hydro plant Canadian Entitlement • average 1,320 megawatts capacity and 4,540 gigawatt hours of (Canada’s share of the
