Why is our watershed so special?
Twin Creek drains into the Great Miami River. The name Miami was originally the designation of the tribe who bore the name of "Tewightewee." In the Ottawa language, it signified "mother" and the Shawanoese called the river Shi,me,a,mee,sepe or "Big Miami River." The settlers who constructed flatboats in Piqua knew the dangerously swift and crooked channels downstream from Troy as the "Ninety-nine Islands." The Miami Valley was also known for its lush vegetation, abundant water resources, Ohio-Erie canal, and rich archeological past. Today, the valley is known for its water supply, recreation, industries, productive farmland, and high quality tributaries. Originating upstream from Indian Lake, the Great Miami River flows southwest to its confluence with the Ohio River west of Cincinnati, OH. The Great Miami is one the 10 major rivers in Ohio. In the state, it is one of six major rivers that drain to the Ohio River (the other four major rivers drain to Lake Erie).
Twin Creek watershed is 46.2 miles long with the drainage of 316 square miles and is of special interest because the quality of its fish and macroinvertebrate communities and physical habitat are among the highest of any Ohio stream. Ohio Environmental Protection Agency described Twin Creek as "home to the most exceptionsl macroinvertebrate community and the second most exceptional fish community in Ohio and one the top 25 streams in the U.S. in terms of biota and water quality".
