  • Idaho Power Company's Fall Chinook Salmon Hatchery
    IDAHO POWER COMPANY’S FALL CHINOOK SALMON HATCHERY PROGRAM Stuart Rosenberger, Paul Abbott, James Chandler 1221 W. Idaho St., Boise, Idaho Background The current Idaho Power Company (IPC) fall Chinook salmon program was established to provide mitigation for losses associated with the construction and operation of Brownlee, Oxbow, and Hells Canyon dams which together form the Hells Canyon Complex. IPC’s current mitigation goal is to produce 1 million fall Chinook salmon smolts annually (see Origination of Idaho Power Company’s Hatchery Mitigation Program section for more details). Oxbow Hatchery, funded by IPC and operated by the Idaho Department of Fish and Game, is responsible for the incubation and rearing of up to 200,000 subyearling fall Chinook salmon. The hatchery is located on the Snake River downstream of Oxbow Dam near the IPC village known as Oxbow, Oregon (Figure 1). IPC also contracts with the Oregon Department of Fish and Wildlife (ODFW) for the production of an additional 800,000 subyearling fall Chinook salmon that were originally reared at ODFW’s Umatilla Hatchery and are now reared at ODFWs’ Irrigon Hatchery, both of which are located near the town of Irrigon, Oregon. Fish reared at both Oxbow and Umatilla/Irrigon hatcheries are released into the Snake River directly below Hells Canyon Dam with the exception of brood years 2003 to 2005 in which some of the production was released at the Nez Perce Tribe’s Pittsburg Landing acclimation facility. Similar to other fall Chinook salmon programs in the Snake Basin, Oxbow and Umatilla/Irrigon hatcheries receive eyed eggs from Lyons Ferry Hatchery, as it is one of only two broodstock holding and spawning facilities for fall Chinook salmon in the Snake Basin.

  • 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.
