Lower Great Miami Watershed

Most of the Lower Great Miami Watershed is in Ohio, but it does extend into two small disjunct parts of southeastern Indiana. The northern part drains the eastern fourth or so of Union County as well as a tiny bit of the southeastern corner of Waybe County and a small part of northeastern Franklin County, mostly via Little Four Mile Creek and Indian Creek. The southern part drains a small portion of the eastern part of Dearborn County. The watershed drains about 41,000 acres of Indiana.
