The Platte River valley in central Nebraska is defined here by a sophisticated network of irrigation and water management infrastructure, most notably the Tri County Supply Canal and the Thirtymile Canal. This 2011 survey documents a landscape of engineered waterways feeding into a series of reservoirs including West Midway Lake, Central Midway Lake, and East Midway Lake. These water bodies are secured by a chain of earth dams, such as Earth Dam- Canal Mile 515 Dam, which support the regional agricultural economy.
