June 2015 Prepared by Rocky Mountain Econometrics, Anthony Jones In early 2015 Idaho Rivers United asked Rocky Mountain Econometrics (RME) to bring its expertise to the subject and revisit the FREIS for the purpose of calculating the cost of replacing the energy produced by the LSRD in current (2015) dollars. To that end, the following […]
July 2015 Prepared by Jim Waddell and Linwood Laughy In its 2002 Lower SnakeRiver Juvenile Salmon Migration Feasibility Report, the Walla Walla District of the U.S. Army Corps of Engineers vastly understated the costs of maintaining and operating four dams on the lower Snake River in eastern Washington State. The report concluded that modifications to […]

February 2016 By Johnny Mojica, Research Analyst, Earth Economics Ken Cousins, PhD, Ecological Economist, Earth Economics Tania Briceno, PhD, Ecological Economist, Earth Economics This report presents a thorough analysis of the benefits and costs of the four Lower Snake River dams in both “keep dam” and “breach dam” scenarios. The dams were originally purposed for […]
In the 1960’s and 1970’s the U.S. Army Corps of Engineers constructed four dams on the lower Snake River without specific measures to allow juvenile salmon and steelhead to migrate downstream and out to the ocean. As a result, these dams killed millions and millions of juvenile salmon and steelhead every year. In the 1990’s […]

January 2017 By John Twa, Mechanical Engineer The four lower Snake River locks and dams were completed in the 1960’s and 1970’s after congressional authorization to provide river navigation to eastern Washington and Lewiston, Idaho. Each of the four, 100 foot high dams created flatwater reservoirs with sufficient depth to allow freight traffic by barge. […]
