River Description


Congress authorized construction of the four dams on the Lower Snake River in 1945 and during the time period 1955 to 1975 the Army Corps of Engineers constructed Ice Harbor, Lower Monumental, Little Goose, and Lower Granite. The Corps documents 63 named rapids that were in existence prior to construction of these dams. Lewis and Clark encountered these rapids on their journey down the river in October 1805. Removing the dams would open up new opportunities for kayaking and rafting along 140 miles of restored river and would attract visitors from across the country.

In February 2002, the US Army Corps of Engineers released the Lower Snake River Juvenile Salmon Migration Feasibility Report/Environmental Impact Statement that includes a review of the economics of dam removal. In a study of potential river users, and not including recreational fishing, results showed that a large percentage of total general recreation visitation to a free flowing lower Snake River would originate from distant areas resulting in an annual contribution of $310.5 million (1998 dollars). The study found that current reservoirs are primarily local-use areas with visitors coming from 100 to 120 miles away. Reservoir users do not travel long distances as there are numerous reservoirs in the local area, including Lake Wallula downstream from Ice Harbor Dam very near the Tri-Cities area, Dworshak reservoir near Lewiston, Idaho, and three large lakes near Spokane, Washington. Those desiring a river- based recreation experience in contrast are willing to travel greater distances to visit free-flowing rivers. Demand for paddlesports would be for over 300,000 user days following dam removal.

Upper Grande Ronde Rapids

The Snake River along this section is the shadow of the river it once was. I will gladly pick up a shovel and help them remove the 4 Lower Snake River Dams, if we can have a free flowing Lower Snake. This would be an incredible multi-day float trip and can only hope that I am able to see it as the salmon used to. Please check out SOS's website, get involved and bring the salmon and the Snake River back.

Public Process for Snake River Dams Underway

9/30/2016
Thomas O'Keefe

Public Scoping Hearings have been scheduled this fall in Washington State, Oregon, Idaho and Montana to discuss the fate of Snake River Dams and their impact on salmon resources in the Snake River Watershed. We are encouraging the paddling community to engage in this public process which has implications for the overall health of the Snake River ecosystem and tributaries like the Lochsa, Selway, and Salmon River.
