Map outlining Gravity Plan
Subject
Irrigation -- Washington (State) -- Columbia River Valley.
Description
This map taken from a 1925 brochure illustrates the series of tunnels and dams designed to channel water from the Pend Oreille River to the Columbia Basin. By maintaining a path that moved water downhill, the Gravity Plan proposed to irrigate the Columbia Basin without the use of pumps. This brochure was created by the Columbia Basin Irrigation League, who championed this plan throughout the 1920s.
