Green Valley State Park

The area used to be filled with tallgrass prairie, but much of that was gone by the time the Iowa Department of Natural Resources (IDNR) bought the land in 1950. Due to a drought in the 1930s, Summit Lake in Creston had no water in 1934 which led to Green Valley Lake being constructed in 1950. The man-made lake was meant to be used for recreation and for the Southwestern Federal Power Cooperative. The recreation area and Green Valley Lake was dedicated as a state park on September 20, 1953. The lake was renovated in 1974 with bluegills, crappies, channel catfish, and largemouth bass being added to it. In the 1980s, a causeway was constructed over the northernmost part of Green Valley Lake to help improve the water's quality. the IDNR started a departmental committee in 1994 to create a framework for all Iowa state parks, with Green Valley State Park being chosen as the first one to implement the changes. A 1994 plan by the Natural Resources Conservation Service, private individuals, and park visitors created nine separate areas for management to protect the state park as well as its lake. ==Resources==
