==History==
The need for storage reservoirs in the Kitakami River valley for irrigation purposes was recognized by the Meiji government at the start of the 20th century, due to repeated crop failures and conflicts between various communities over water rights. The river also suffered from severe environmental problems with acidic runoff from upstream mining operations. Plans for a series of dams was initiated in 1941 by the Ministry of Agriculture and Forestry, but all work was halted during World War II. The plan was revived after the war, and the Toyosawa Dam was the third to be constructed (after the Sannōkai Dam and the Gandō Dam). Construction was begun in 1949, and completed in 1961 by the Kajima Corporation.
