Upper : Adult Passage Scenarios for Waneta, Brilliant and Keenleyside

Bill Green Canadian Columbia River Inter-tribal Fisheries Commission Key points

• Each of these dams is ‘next in line’ once salmon are restored to the transboundary reach (upstream of GCD) • Passage feasibility has been investigated at each of these dams through EA processes (1997 through 2005 • There are feasible passage technologies at each • Legally binding commitments are in place (ALGS and BRD) for generating station owners to provide upstream and downstream passage for salmon

Hugh and Generating Station

BC Hydro Columbia Power Corporation and Hugh Keenleyside Dam and Arrow Lakes Generating Station

Anadromous salmon Sockeye, steelhead, chinook (spring, species/runs summer and fall) Estimated run timing range July to November - upstream Estimated run timing range April to September – downstream Range of flows 140 to 3,870 m

Tailwater elevation 419.0 to 422.5 m. (3.5 m. range)

Reservoir elevations 420.0 to 440.7 m. (20.7 m. range)

Head (range) up to 21.7 m. Hugh Keenleyside Dam and Arrow Lakes Generating Station Configuration Earthfill embankment (south bank), concrete gravity structure with surface spill and low level outlet gates, navigation lock. Two turbine powerhouse on separate, north bank intake canal Upstream • Collection chamber with 2 entrances adjacent to passage powerhouse; pump from tailrace for additional elements attraction flow • Short ladder to channel along canal • Join proposed ladder from dam; egress to reservoir • Good attraction flow conditions in powerhouse tailrace Downstream • Surface attraction flow channel above turbine passage intakes elements • Block 30% of turbine intakes • SAF of 85 m3/s.; 76.5 m3/s. returned to intakes • Collection box then 8.5 m3/s. flow down pipe to tailrace • Unresolved challenges at dam/spill gates Arrow Lakes Generating Station: CPC/CBT Commitment

Legally binding commitment (pursuant to the request of Columbia Basin First Nations): “CPC has committed to install fish passage facilities at KPP150 to allow the passage of adult salmon upstream and the passage of smolt downstream in cooperation with the construction of complementary facilities by BC Hydro at the Keenleyside Dam, if all obstacles to the upstream and downstream migration of salmon have been removed from the main stem of the Columbia River in the US, and a consensus has been reached between MELP, DFO and CCRIFC about the desirability of these measures.” Brilliant Dam and Expansion Project Brilliant Dam and Expansion Project Brilliant Dam and Expansion Project

Anadromous salmon species/ Steelhead and chinook (spring, runs summer and fall)

Estimated run timing range - July to November upstream Estimated run timing range – April to September downstream Range of flows 450 to 2850 m

Tailwater elevation +/- 422 m.

Reservoir elevations 448 to 451 m. (run of river, limited storage) Head (range) 26 to 29 m.** Brilliant Dam and Expansion Project Configuration Concrete gravity dam with (old powerhouse) 8 power intakes/4 turbines and 8 gated surface spillways. New powerhouse has tunnel intake and two turbines Upstream • Collection chamber with 2 entrances downstream passage side of the new powerhouse elements • Ladder under new powerhouse service bay and up left side of intake tunnel • Alternative ladder layouts possible • Additional ladder MAY be required on north bank Downstream • Variety of passage technologies examined passage • Recommendation to select technology when elements downstream passage required • Initial suggest of turbine passage with (new) Kaplan turbines and (old) Francis turbines Brilliant Dam and Expansion Project Brilliant Expansion Project: CPC/CBT Commitment

The following is a legally binding project owners commitment under the BC Environmental Assessment Act (inserted at the request of Columbia Basin First Nations): ! "BEPC will install fish passage facilities at Brilliant if, in the future, salmon runs are re-established into the Canadian portion of the Columbia River, and if fisheries agencies permit the installation." Waneta Expansion Powerplant Project Waneta Expansion Powerplant Project Waneta Expansion Powerplant Project

The following is a legally binding project owners commitment under the BC Environmental Assessment Act (inserted at the request of Columbia Basin First Nations): ! “The WEP final Project Concept to be constructed will not preclude the ongoing potential for fish passage or fish resource use of concern to First Nations. ! (Not successful in securing a stronger commitment. Will need to rely on the relationships between First Nations and the Columbia Power Corporation and especially the Columbia Basin Trust.)
