1 map : 27 x 40 cm.<br>Before the creation of the Walla Walla District on November 1, 1948, all work done by the War Department's Corp of Engineers on waterways in the west was handled by the district headquarters in Portland, Oregon. Most jobs done under this district pertained to navigational concerns. However, by the 1930s, the Corps would involve themselves in all types of water uses--including the erection of dams for hydropower. The Walla Walla District built eight dams on the Columbia and Snake River systems. During the time this map was rendered (1955), the Walla Walla District was busy constructing four dams on the Snake River, as part of the Lower Snake River Project (authorized in 1945). The Corps had just completed the McNary Dam and Locks on the Columbia River in 1954 and were working on other projects within their district boundary--as shown here. The Walla Walla District is nearly the same as the boundaries of the Snake River watershed--infiltrating six states (Washington, Oregon and parts of Idaho, Wyoming, Nevada and Utah) and 107,000 square miles.
