Transportation Methods, Greenhouse Gas Emissions, and the Lower Snake River Reservoirs
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
Estimate of Greenhouse Gas Emissions for the Lower Snake River Dams and Reservoirs using the All-Res Modeling Tool
By Tell The Dam Truth, Inc. The four Lower Snake River dams, reservoirs, and their hydropower systems (“LSR dams”) – Lower Granite, Little Goose, Lower Monumental, and Ice Harbor – in the state of Washington have been at the center of national controversy in recent months. Because the dams block
