DAMS	The Snake River serves an important function in the Palouse region as it provides the means to transport significant amounts of grain and other commodities that are produced in the region. The construction of four major dams on the Snake River in the 1950’s to 1970’s, complete with lock facilities, enables ocean going vessels to travel inland as far as Lewiston , Idaho. Three of these dams serve the Palouse Region: Lower Monumental Dam, Little Goose Dam and Lower Granite Dam. There are four port Districts in the region: the Ports of Clarkston, Columbia, Garfield and Whitman. The Port of Whitman ’s three industrial port sites are the Ports of Wilma, Central Ferry and Almota. Outbound shipments consist primarily of agricultural commodities and lumber. Port facilities located along the Snake River are operated by Port Districts in each county. Specific ports include the following: Port of Clarkston Port of Columbia Port of Garfield Port of Whitman County : Port of Almota Port of Central Ferry Port of Wilma The following shows the volume of commodities shipped through area locks. Grain shipments are a major part of the port's activities. Grain shipments are a major part of the ports’ freight activities, accounting for 80% of the total commodities shipped from the Port of Clarkston and Wilma (Port of Whitman County) and 85% to 90% of the total shipment from the Ports of Garfield and other Port of Whitman County on-water sites (Central Ferry and Almota).
