Dams and Hydroelectricity in the Columbia
COLUMBIA RIVER BASIN: DAMS AND HYDROELECTRICITY The power of falling water can be converted to hydroelectricity A Powerful River Major mountain ranges and large volumes of river flows into the Pacific—make the Columbia precipitation are the foundation for the Columbia one of the most powerful rivers in North America. River Basin. The large volumes of annual runoff, The entire Columbia River on both sides of combined with changes in elevation—from the the border is one of the most hydroelectrically river’s headwaters at Canal Flats in BC’s Rocky developed river systems in the world, with more Mountain Trench, to Astoria, Oregon, where the than 470 dams on the main stem and tributaries. Two Countries: One River Changing Water Levels Most dams on the Columbia River system were built between Deciding how to release and store water in the Canadian the 1940s and 1980s. 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 CRT: power generation) with regional and provincial concerns such as ecosystems, recreation and cultural values. 1. coordinates flood control 2. optimizes hydroelectricity generation on both sides of the STORING AND RELEASING WATER border. 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. -
The Hells Canyon Dam Controversy
N 1956, AT THE TENDER AGE OF THIRTY-TWO, Frank Church made a bold bid for the United States Senate. After squeak- I ing out a victory in the hotly contested Idaho Democratic pri- mary, Church faced down incumbent Senator Herman Welker, re- ceiving nearly percent of the vote. One issue that loomed over the campaign was an emerging dis- pute over building dams in the Snake River’s Hells Canyon. While Church and other Democrats supported the construction of a high federal dam in the Idaho gorge, their Republican opponents favored developing the resource through private utility companies. Idaho EVOLUTION voters split on the issue, and so, seeking to avoid a divisive debate, Church downplayed his position during the general election “be- of an cause it was not a winning issue, politically.”1 Senator Frank Church Although Church won the election, he could not escape the is- sue. Indeed, his victory and subsequent assignment to the Senate Committee on Interior and Insular Affairs put him at the center of a growing controversy about damming Hells Canyon. Over the next eighteen years, Church wrestled with balancing Idaho’s demand for economic growth and his own pro-development beliefs with an emerging environmental movement’s demand for preservation of nature—in Idaho and across the nation. As he grappled with these competing interests, Church under- went a significant transformation. While Church often supported development early in his Senate career, he, like few others of his time, began to see the value of wild places and to believe that rivers offered more than power production opportunities and irrigation water. -

North Pacific Division DOEIEIS-O 1 70 November 1995 PUBLIC INVOLVEMENT IN THE SOR PROCESS The Bureau of Reclamation. Corps of Engineers. and Bonneville Power Administration wish to thank those who reviewed the Columbia River System Operation Review (SOR) Draft EIS and appendices for their comments. Your comments have provided valuable public, agency. and tribal input to the SOR NEPA process. Throughout the SORt we have made a continuing effort to keep the public informed and involved. Fourteen public scoping meetings were held in 1990. A series of public roundtables was conducted in November 1991 to provide an update on Lhe status of SOR studies. The lead agencies went back to most of the 14 communities in 1992 with 10 initial system operating strategies developed from the screening process. From those meetings and other consullalioDs, seven SOS a1ternatives (with options) were developed and subjected to full-scale analysis. The analysis results were presented in the Draft EIS released in July 1994. The lead agencies also developed alternatives for the other proposed SOR actions. including a Columbia River Regional Forum for assisting in the determination of future SOSs, Pacific Northwest Coordination Agreement alternatives for power coordination. and Canadian Entitlement Allocation Agreements alternatives. A series of nine public meetings was held in September and October 1994 to present the Draft EIS and appendices and solicit public input on the SOR. The lead agencies-received 282 fonna1 written comments. Your comments have been used to revise and shape the alternatives presented in the Final EIS.
