	Dams of the Columbia Basin
		The dam operates in balance with the Mica reservoir but was not constructed under the terms of the1964 Columbia River Treaty with the U.S. Revelstoke Dam.
		The storage dams ensure the necessary amount of water will be in the riverbed to meet hydroelectric demands regardless of season within the basin and beyond its borders.
		Keenleyside is a earthfill and concrete gravity dam that has four spillways and eight low level ports.

	BC Hydro - Recreation Areas - Hugh Keenleyside Dam
		Hugh Keenleyside Dam, eight km (five miles) upstream from Castlegar, was the second of three Columbia River Treaty dams to be built by BC Hydro.
		The Columbia River Treaty allowed construction of dams to regulate the flow of the Columbia River and end the annual threat of flood damage in BC, Washington and Oregon.
		The dam is about 52 m (171 feet) high, with a crest length of 853.4 m (2,800 feet).

		Revelstoke Dam is Canada's second generating project on the Columbia River and one of four dams in B.C. that regulate the flow of the Columbia.
		Three of the dams, Mica, Hugh Keenleyside and Duncan, were built as a result of the Columbia River Treaty, signed by Canada and the United States in 1964.
		The hydroelectric complex comprises a 175 m high concrete gravity dam in Little Dalles Canyon, a 122 m high earthfill dam on the west bank of the river, and a powerhouse in the riverbed, immediately downstream of the concrete dam.

	Mica Dam - Wikipedia, the free encyclopedia
		Mica Dam is a hydroelectric dam spanning the Columbia River 135 km north of Revelstoke, British Columbia, Canada.
		The Mica Dam, aptly named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world.
		The dam's underground powerhouse was the largest in the world at the time of its construction, and was the first installation of SF

		The Hugh Keenleyside Dam is constructed, flooding the Upper and Lower Arrow two lakes to create one reservoir of water and eliminating an estimated 30% of spawning/rearing habitat.
		Revelstoke Dam is constructed, flooding 150 km of mainstem Columbia River and 200 km of tributaries, and significantly impacting fish stocks and habitat over a 11,560 hectare area.
		Cumulative impact of dams was the estimated loss of 66% of the bull trout population.

		The purpose of this socio-economic impact assessment is to update the 1995 Keenleyside socio-economic assessment (completed by McDaniels Research Ltd.), which evaluated a proposed 220 MW powerplant at Keenleyside and a transmission line to Selkirk substation.
		The undeveloped area upstream of the dam known as "Driftwood Beach", presently used as a recreation area by local residents, would be permanently closed at the beginning of construction.
		Shore angling at the rock promontory 400 metres downstream of the dam would be displaced during construction, but would re-open when the project is complete, with additional parking facilities and trail access to the river.

		Dams that most directly affect TDG at the border are located on the Columbia mainstem, the Kootenay River and the Pend Oreille River as shown in Figure 1.
		Currently, Keenleyside has no capability to generate power but there are plans to start construction of two turbines capable of generating a total of 150 MW of power.

	keenleyside powerhouse project
		The original Hugh Keenleyside Dam, completed in 1969, was one of three large dams constructed in Canada on the Columbia River during the 1960s and 1970s under the terms of the Columbia River Treaty.
		(1,400-ft.) section, downstream of the dam, consists of a concrete faced rock-filled dam that contains the south side of the channel, rock excavation that contains the north side of the channel and rock excavation that contains the powerhouse and tailrace channel.
		Reclaiming borrow locations from the previous construction of the Keenleyside Dam during the 1960s is another example of the construction team’s environmental efforts.

	AMBIENT WATER QUALITY OBJECTIVES FOR THE LOWER COLUMBIA RIVER - HUGH KEENLYSIDE DAM TO BIRCHBANK
		Streamflow regulation of this reach began in 1968 with the construction of the Hugh Keenleyside Dam.
		Installation of turbines in the Keenleyside Dam, as proposed by BC Hydro, would ameliorate gas supersaturation for most of the year when the sluiceway is not used.
		Provisional water quality objectives are set to protect a variety of designated water uses between the Keenleyside Dam and Birchbank including: aquatic life (and their habitats), wildlife consumption of aquatic life, recreational use, aesthetic values, and drinking water.

		The three dams in B.C. were developed to provide water storage for power generation in the U.S. Mica Dam, which forms Kinbasket Reservoir, is the only installation of the three to have a powerhouse.
		The Revelstoke Dam and Generating Stations, located 130 kilometres downstream from Mica, was not built under the terms of the Columbia River Treaty, but benefits from the storage in the Mica reservoir.

		The dam flooded 150 kilometers of the mainstem Columbia River and 200 kilometers of tributary streams.
		As well, prior to dam construction on the Columbia River in the United States, the Arrow Lakes systems supported anadromous - or river spawning - runs of chinook salmon and steelhead trout that fought their way a thousand miles from the Pacific Ocean to spawn and regenerate their species.
		Charged with compensating for the damage to species and habitats caused by the dams, we were also charged with building the Program based on public consultation to encourage understanding of the state of the environment and public involvement in identifying and delivering fish and wildlife projects.

		By 1935, Roosevelt was convinced that a high dam at the Grand Coulee could meet his administration's goals of providing relief to unemployed workers, cheap public power, and a planned relocation of farmers who were struggling to eke out a living on poor farm lands in other parts of the county.
		Since most of the Columbia River upstream of the Grand Coulee Dam is in Canada, the task of exploring possibilities for upstream storage fell to the International Joint Commission, which created an International Columbia River Engineering Board (composed of two members from each county) to analyse the situation.
		The Act requires that the Council's program for offsetting the effects of dams on salmon and other fish and wildlife populations be financed by BPA hydropower revenues and by the federal agencies controlling the dams producing hydropower.

	IUCN Red List of Threatened Species: Acipenser transmontanus (Upper Columbia River subpopulation)
		Construction of Keenleyside, Mica, and Revelstoke dams on the mainstem Columbia River, Brilliant Dam on the lower Kootenay River, and Waneta Dam on the lower Pend d'Oreille River further fragmented the population and altered the natural river regime.
		Dam construction effects were exacerbated by additional impacts such as pollution and waterfront developments.
		The abundance of white sturgeon from the Columbia River mainstem between Keenleyside Dam and the Canada-U.S. border was most recently assessed in 1995, when a population of 1,120 individuals (95% CI = 980 to 1,300) was estimated (RL&L 1996a).

	Abstract #: 951509852-62
		Prior to construction of Keenleyside Dam in 1968, white sturgeon (Acipenser transmontanus) populations in the upper Columbia River basin in Canada were contiguous.
		The dam resulted in two separate populations, one in the upstream reservoir and another in the 100km long riverine section between the dam and Lake Roosevelt, the next downstream reservoir.
		The riverine resident population spawns below Waneta Dam, a load-shaping facility with near-surface water withdrawals, situated at the confluence of the Pend d'Oreille and Columbia rivers.

		After the Grand Coulee dam was built in the 1940's salmon passage in the Columbia River to Canada was abruptly halted.
		Presently the Army Corps of Engineers in the US is developing a series of options on how to restore salmon, including removal of dams (4 dams on the lower Snake), status quo (barging of fish) and more of the status quo (barging more fish and flushing more water through the dams).
		In Canada new generating turbines are presently being installed by Columbia Basin Trust and associates at Keenleyside Dam just downstream of Revelstoke, where no power generating capability has previously existed, and at a location that has potential to impact further the floodplain and estuaries of the Upper Arrow Reservoir.
