About the Mill Creek Watershed
The Mill Creek Watershed is defined as the land area that drains to the Mill Creek and its tributaries. Located in southwest Ohio, it contains all or part of 36 cities, villages, and townships. The Mill Creek starts in Liberty Township and flows 28 miles southward to its mouth at the Ohio River. Major concerns in the Watershed include flooding, storm water runoff, water quality and stream habitat disruptions. All of these factor into our quality of life and the economic well-being of our communities.
The watershed covers 106 square miles in Southwest Ohio. About a half of the city of Cincinnati, a third of Hamilton County and a tenth of Butler County lie in it. More than 450,000 people are estimated to live within the watershed's natural boundaries. Many international companies operate plants along the banks of the creek, including Procter & Gamble, General Electric, Ford, Ralston-Purina, Formica and Henkel. The Mill Creek Valley has been the heart, soul and industrial center of the Cincinnati region.
