Columbia River Treaty: Recommendations December 2013
L O CA L GOVERNMEN TS’ COMMI TTEE Columbia River Treaty: Recommendations December 2013 The BC Columbia River Treaty Local Governments’ Committee (the Committee) has prepared these Recommendations in response to the Columbia River Treaty-related interests and issues raised by Columbia River Basin residents in Canada. These Recommendations are based on currently-available information. They have been submitted to the provincial and federal governments for incorporation into current decisions regarding the future of the Columbia River Treaty (CRT). The Committee plans to monitor the BC, Canadian and U.S. CRT-related processes and be directly involved when appropriate. As new information becomes available, the Committee will review this information, seek input from Basin residents, and submit further recommendations to the provincial and federal governments, if needed. The CRT Local Governments’ Committee will post its recommendations and other documents at www.akblg.ca/content/columbia-river-treaty. For more information contact the Committee Chair, Deb Kozak ([email protected] 250 352-9383) or the Executive Director, Cindy Pearce ([email protected] 250 837-3966).

White Paper on COLUMBIA RIVER POST-2024 FLOOD RISK MANAGEMENT PROCEDURE
White Paper on COLUMBIA RIVER POST-2024 FLOOD RISK MANAGEMENT PROCEDURE U.S. Army Corps of Engineers Northwestern Division September 2011 This page intentionally left blank PREFACE The Columbia River, the fourth largest river on the continent as measured by average annual flow, provides more hydropower than any other river in North America. While its headwaters originate in British Columbia, only about 15 percent of the 259,500 square miles of the river’s basin is located in Canada. Yet the Canadian water accounts for about 38 percent of the average annual flow volume, and up to 50 percent of the peak flood waters, that flow on the lower Columbia River between Oregon and Washington. In the 1940s, officials from the United States and Canada began a long process to seek a collaborative solution to reduce the risks of flooding caused by the Columbia River and to meet the postwar demand for energy. That effort resulted in the implementation of the Columbia River Treaty in 1964. This agreement between Canada and the United States called for the cooperative development of water resource regulation in the upper Columbia River Basin. The Columbia River Treaty has provided significant flood control (also termed flood risk management) and hydropower generation benefiting both countries. The Treaty, and subsequent Protocol, include provisions that both expire on September 16, 2024, 60 years after the Treaty’s ratification, and continue throughout the life of the associated facilities whether the Treaty continues or is terminated by either country. This white paper focuses on the flood risk management changes that will occur on that milestone date and satisfies the following purposes: 1. -
The Columbia Basin Tribes and First Nations Jointly Developed This Paper To
Agenda Item E.2 Attachment 1 (Electronic Only) March 2021 a | EXECUTIVE SUMMARY he Columbia Basin tribes and First Nations jointly developed this paper to Tinform the U.S. and Canadian Entities, federal governments, and other re- gional sovereigns and stakeholders on how anadromous salmon and resident fish can be reintroduced into the upper Columbia River Basin. Reintroduction and res- toration of fish passage could be achieved through a variety of mechanisms, includ- ing the current effort to modernize the Columbia River Treaty (Treaty). Restoring fish passage and reintroducing anadromous fish should be investigated and imple- mented as a key element of integrating ecosystem-based function into the Treaty. Anadromous fish reintroduction is critical to restoring native peoples’ cultural, harvest, spiritual values, and First Foods taken through bilateral river development for power and flood risk management. Reintroduction is also an important facet of ecosystem adaptation to climate change as updated research indicates that only the Canadian portion of the basin may be snowmelt-dominated in the future, making it a critical refugium for fish as the Columbia River warms over time. This transboundary reintroduction proposal focuses on adult and juvenile fish pas- sage at Chief Joseph and Grand Coulee dams in the U.S. and at Hugh Keenleyside, Brilliant, Waneta and Seven Mile dams in Canada. Reintroduction would occur incrementally, beginning with a series of preliminary planning, research, and ex- perimental pilot studies designed to inform subsequent reintroduction and passage strategies. Long-term elements of salmon reintroduction would be adaptable and include permanent passage facilities, complemented by habitat improvement, ar- tificial propagation, monitoring, and evaluation. -

BC Hydro Climate Change Assessment Report 2012
POTENTIAL IMPACTS OF CLIMATE CHANGE ON BC HYDRO’S WATER RESOURCES Georg Jost: Ph.D., Senior Hydrologic Modeller, BC Hydro Frank Weber; M.Sc., P. Geo., Lead, Runoff Forecasting, BC Hydro 1 EXecutiVE Summary Global climate change is upon us. Both natural cycles and anthropogenic greenhouse gas emissions influence climate in British Columbia and the river flows that supply the vast majority of power that BC Hydro generates. BC Hydro’s climate action strategy addresses both the mitigation of climate change through reducing our greenhouse gas emissions, and adaptation to climate change by understanding the risks and magnitude of potential climatic changes to our business today and in the future. As part of its climate change adaptation strategy, BC Hydro has undertaken internal studies and worked with some of the world’s leading scientists in climatology, glaciology, and hydrology to determine how climate change affects water supply and the seasonal timing of reservoir inflows, and what we can expect in the future. While many questions remain unanswered, some trends are evident, which we will explore in this document. 2 IMPACTS OF CLIMATE CHANGE ON BC HYDRO-MANAGED WATER RESOURCES W HAT we haVE seen so far » Over the last century, all regions of British Columbia »F all and winter inflows have shown an increase in became warmer by an average of about 1.2°C. almost all regions, and there is weaker evidence »A nnual precipitation in British Columbia increased by for a modest decline in late-summer flows for those about 20 per cent over the last century (across Canada basins driven primarily by melt of glacial ice and/or the increases ranged from 5 to 35 per cent). -
Columbia Lake Quick Fact Sheet
COLUMBIA LAKE QUICK REFERENCE SHEET JUST A FEW AMAZING THINGS ABOUT OUR AMAZING LAKE! . Maximum length – 13.5 km (8.4 mi) . Maximum width – 2 km (1.2 mi) . Typical depth – 15 ft . Average July water temperature – 18 C – making it the largest warm water lake in East Kootenay . Surface Elevation – 808m (2,650 ft) .Area – 6,815 acres (2,758 hectares) . Freezing – last year, it was observed the lake froze on December 7, 2016 and thawed on March 29, 2017. Columbia Lake is fed by several small tributaries. East side tributaries include Warspite and Lansdown Creeks. West Side tributiaries include Dutch, Hardie, Marion and Sun Creeks. Columbia Lake also gets a considerable amount of water at the south end where water from the Kootenay river enters the lake as groundwater. The water balance of Columbia Lake is still not fully understood. The Columbia Lake Stewardship Society continues to do research in this area. Columbia Lake got its name from the Columbia River. The river was so named by American sea captain Robert Gray who navigated his privately owned ship The Columbia Rediviva through its waters in May 1792 trading fur pelts. Columbia Lake is the source of the mighty Columbia River, the largest river in the Pacific Northwest of North America. The Columbia River flows north from the lake while the neighbouring Kootenay flows south. For approximately 100 km (60 mi) the Columbia River and the Kootenay River run parallel and when they reach Canal Flats, the two rivers are less than 2 km (1.2 mi) apart. Historically the Baillie- Grohman Canal connected the two bodies of water to facilitate the navigation of steamboats (although only three trips were ever made through it). -

Proceedings, Canadian Geotechnical Conference Halifax, NS, pp 367-374. Why a Canadian geotechnical achievement? Photographs Downie Slide is located on the Columbia River within BC Hydro’s Revelstoke Reservoir. The slide is in mica schist/gneiss bedrock with multiple water levels. At nearly 10 km2 in area, 250 m deep and approximately 1.5 billion m3 in volume, this is the world’s largest known landslide stabilization project. Construction of the Revelstoke Dam was contingent on the stabilization of Downie Slide. Key safety issues were the potential for reservoir blockage, a landslide-generated wave, and upstream flooding of Mica Dam, approximately 70 km to the north. After a thorough site investigation by BC Hydro and many consultants, and an extensive public consultation, drainage was selected as the appropriate method for stabilization Aerial view of Downie Slide (outlined in red) looking up the Revelstoke Reservoir and Columbia The drainage included 2,450 m of adits, primarily located in the River valley.
