Miami Conservancy District
From Wikipedia, the free encyclopedia
The Miami Conservancy District is a river management agency operating in Southwest Ohio to control flooding of the Great Miami River and its tributaries. It was organized in 1914 following the catastrophic flood of the Great Miami River in March of 1913, which hit Dayton, Ohio particularly hard, known as the Great Dayton Flood of 1913. Designed by Arthur Ernest Morgan, the Miami Conservancy District built levees, straightened the river channel throughout the Miami Valley, and built five dry dams on various tributaries to control flooding. The district and its projects are unusual in that they were funded almost entirely by local tax initiatives, unlike similar projects elsewhere which were funded by the federal government and coordinated by the U.S. Army Corps of Engineers.

The district manages five dry dams. They are hydraulic fill dams constructed from 1919 to 1921 using fill trestles.
Located near Englewood, Ohio, Englewood dam is the largest of the dams maintained by the district. It regulates the flow of the Stillwater River into the Great Miami River. It consists of 3.5 million cubic yards (2.7 million m³) of earth, is 110 feet (34 m) high and stretches 4,716 feet (1,437 m). The straight road across the top is said to be exactly 1 statute mile long. The dam can contain 209,000 acre-feet (258 million m³) of flood water over 6350 acres (26 km²). It was constructed in 1919 and consists of as much earth as the Great Pyramid of Giza.
Located near Germantown, Ohio, Germantown Dam regulates the flow of Twin Creek into the Great Miami River. It consists of 865 thousand cubic yards (661,000 m³) of earth, is 100 feet (30 m) high and 1210 feet (369 m) wide. The dam can contain 73 thousand acre-feet (90 million m³) of flood water over 2950 acres (12 km²). It was constructed in 1920.
Located near Fairborn, Ohio, Huffman Dam regulates the flow of the Mad River into the Great Miami River. It consists of 1,665,000 cubic yards (1,273,000 m³) of earth, is 65 feet (20 m) high and spans 3,340 feet (1,020 m). The dam can contain 124 thousand acre-feet (153 million m³) of flood water over 7,300 acres (30 km²).
Located north of Piqua, Ohio outside the village of Lockington, Ohio, Lockington dam regulates the flow of Loramie Creek into the Great Miami River. It consists of 1,135,000 cubic yards (868 thousand m³) of earth, is 69 feet (21 m) high and spans 6,400 feet (1,950 m). The dam can contain 63 thousand acre-feet (78 million m³) of flood water over 3,600 acres (15 km²). It was constructed in 1919.
Located near Vandalia, Ohio, Taylorsville Dam regulates the Great Miami River. It consists of 1,235,000 cubic yards (944 thousand m³) of earth, is 67 feet (20 m) high and spans 2,980 feet (908 m). When full, the dam would inundate 9,650 acres (39 km²). It was constructed in 1919.
The Miami Conservancy District builds and plans a system of bikeways along the Miami corridor. Currently, bike trails follow the Great Miami River much of the way through Montgomery and Warren Counties. The current northern trail terminus is Taylorsville MetroPark, between Vandalia and Huber Heights. Construction is planned in the near future to extend the trail north through Miami County to Tipp City, Troy, and Piqua.
