The Future of Chiloquin Dam

 

     The Chiloquin Dam has generated a number of negative ecological impacts for the Sprague River. This reality has led to the call by several different groups to have the dam removed from the river. Beginning in 2002, the Bureau of Indian Affairs, which is responsible for the dam, proposed to have the dam removed. In 2005, the U.S. Fish and wildlife service completed a biological opinion which supported the BIA’s call for removal, clearing the way for the planning phase of the project to begin. In the first phase of the removal, a pumping station will be installed on the nearby Williamson River that will replace the irrigation water provided by the dam. This phase is expected to be completed by late 2007. For the second phase, a contract has been awarded to a local company which will be in charge of breaching the actual dam. The Slayden Construction Group of Stayton, Oregon was awarded a multimillion contract by federal government which is solely responsible for funding the removal project. It’s expected that the removal process will be completed by December 2008.

    

 

     The removal of Chiloquin Dam will restore 80 miles of spawning habitat on the Sprague River. Opening up this habitat will allow the Lost River and shortnose suckers to migrate upstream towards their historical spawning habitat. Hopefully the restoration of this habitat will facilitate the recovery of these endangered species, ensuring that they will live and thrive for generations to come.
