  • Chief Joseph Hatchery Program
    Chief Joseph Hatchery Program Draft Environmental Impact Statement DOE/EIS-0384 May 2007 Chief Joseph Hatchery Program Responsible Agency: U.S. Department of Energy, Bonneville Power Administration (BPA) Title of Proposed Project: Chief Joseph Hatchery Program Cooperating Tribe: Confederated Tribes of the Colville Reservation State Involved: Washington Abstract: The Draft Environmental Impact Statement (DEIS) describes a Chinook salmon hatchery production program sponsored by the Confederated Tribes of the Colville Reservation (Colville Tribes). BPA proposes to fund the construction, operation and maintenance of the program to help mitigate for anadromous fish affected by the Federal Columbia River Power System dams on the Columbia River. The Colville Tribes want to produce adequate salmon to sustain tribal ceremonial and subsistence fisheries and enhance the potential for a recreational fishery for the general public. The DEIS discloses the environmental effects expected from facility construction and program operations and a No Action alternative. The Proposed Action is to build a hatchery near the base of Chief Joseph Dam on the Columbia River for incubation, rearing and release of summer/fall and spring Chinook. Along the Okanogan River, three existing irrigation ponds, one existing salmon acclimation pond, and two new acclimation ponds (to be built) would be used for final rearing, imprinting and volitional release of chinook smolts. The Chief Joseph Dam Hatchery Program Master Plan (Master Plan, Northwest Power and Conservation Council, May 2004) provides voluminous information on program features. The US Army Corps of Engineers, Washington Department of Fish and Wildlife, Washington State Parks and Recreation Commission, Oroville-Tonasket Irrigation District, and others have cooperated on project design and siting.

  • Effects of Dams on Native Americans in the Columbia River Basin Elliott
    Dammed Societies: Effects of Dams on Native Americans in the Columbia River Basin Elliott McGill Senior Capstone Project Faculty Advisors: Dr. Jamie Dolan, Dr. Jeremy Johnson, and Dr. David McCanna McGill 1 Abstract Since dam construction began in the New Deal Era, it has represented a dominance of humankind over nature. These massive structures have harnessed, collected, and distributed electricity from the rivers they hold back and allow humans to reap the benefits of that cycle. One of the areas where dams are particularly apparent is in the Columbia River Basin in the Pacific Northwest region of the United States. While the dams in this region certainly have allowed the area to develop and build by using the electricity collected by these dams, they have also had several negative effects on the tribal people in the region who once fished the mighty Columbia during its populous salmon runs and relied on the salmon for nutritional, economic, and cultural reasons. This project seeks to examine the costs of human advancement when it comes to dams, and will do so by studying three dams located in the Columbia River Basin: The Bonneville Dam, The Dalles Dam, and The Grand Coulee Dam. These dams will be studied using Black’s Theory of Law as a framework to examine the manner in which law was applied to each case. The research finds that although the dams certainly provide a useful resource to the people of the region, it has had negative effects on the Native American people who depended on the river.

They are part of a coordinated water Columbia River system is a complex process. Decision-makers management system guided by the 1964 Columbia River Treaty must balance obligations under the CRT (flood control and (CRT) between Canada and the United States.

The ability to store water in reservoirs behind dams means water can be released when it’s needed for fisheries, flood control, hydroelectricity, irrigation, recreation and transportation. Managing the River Releasing water to meet these needs influences water levels throughout the year and explains why water levels The Columbia River system includes creeks, glaciers, lakes, change frequently.

    Bull Trout Final Critical Habitat Justification: Rationale for Why Habitat is Essential, and Documentation of Occupancy Chapter 22 Mid-Columbia Recovery Unit—Mainstem Upper Columbia River Critical Habitat Unit 575 Bull Trout Final Critical Habitat Justification Chapter 22 U.S. Fish and Wildlife Service September 2010 Chapter 22. Mainstem Upper Columbia River Critical Habitat Unit The Mainstem Upper Columbia River CHU is essential for maintaining bull trout distribution within this unique geographic region of the Mid-Columbia RU and conserving the fluvial migratory life history types exhibited by many of the populations from adjacent core areas. It is essential for conservation by maintaining broad distribution within the Mid-Columbia RU across Washington, Idaho, and Oregon. Its location between Chief Joseph Dam in the most northern geographical area and John Day Dam in the most southern area provides key connectivity for the Mid-Columbia River RU. It is essential for maintaining distribution and genetic contributions to the Lower Columbia and Snake River Mainstems and 13 CHUs. Bull trout are known to reside year-round as sub-adults and adults, but spawning adults may utilize the mainstem Columbia River for up to at least 9 months as well. Several studies in the upper Columbia and lower Snake Rivers indicate migration between the Mainstem Upper Columbia River CHU and core areas, generally during periods of cooler water temperatures. FMO habitat provided by the mainstem Columbia River is essential for conservation because it supports the expression of the fluvial migratory life history forms for multiple core areas. In addition, there are several accounts of amphidromous life history forms present between Yakima and John Day Rivers that may still have the potential to express anadromy (see Appendix 1 for more detailed information).
