After the Great Flood of 1913, citizens of the Dayton region were determined to put an end to flooding in the city once and for all. They hired Arthur Morgan to design a flood protection system and worked with Governor James Cox, owner of the Dayton Daily News, to develop a law that would allow for the formation of the Miami Conservancy District (MCD). Morgan and his staff developed an innovative, integrated system that includes five dams that work in conjunction with levees, modified channels, preserved floodplains, and other components to protect the main cities along the Great Miami River between Piqua and Hamilton from flooding. Today, the system has grown to include 55 miles of levee. Together, the dams have stored floodwaters more than 1,770 times since their completion in 1922. After many years of providing flood protection to the region, MCD developed a reputation for its successful projects. Communities started to ask MCD to help with other water-related projects. MCD’s work to improve water quality pre-dates the Clean Water Act by almost 20 years. Today, MCD monitors and studies groundwater (our primary source of drinking water) and surface water to help protect the Great Miami River Watershed’s water resources. In the 1970s, MCD built an 8-mile loop of paved bike trail on or along its river levees in downtown Dayton. Today, MCD owns or maintains 34 miles of paved trails for biking, running, and other recreational activities. The Great Miami, Stillwater, and Mad River Recreation Trails are part of a 300-mile system of paved trails in southwest Ohio. This Dayton Original’s regional model has been replicated all over the country (Tennessee Valley Authority and in the states of Minnesota, Colorado, Michigan and Florida) and in many parts of the world!
