Watershed Description

The Upper Great Miami Watershed flows through Indiana and Ohio and ultimately drains into the Ohio River.  Approximately 79 percent of the land area is in agriculture.  Developed land covers approximately 16 percent of the watershed.

Rivers originate in the upper reaches of the basins in agricultural areas consisting of rolling hills and steep-walled but shallow valleys. Large streams are usually underlain by buried valleys filled with sand and gravel deposited by glacial meltwaters. A significant component of baseflow in some streams is provided by ground-water discharge from glacial and shallow bedrock aquifers. The area contains many lakes and small reservoirs that are used for flood control, water supply, and recreation.  Drainage is toward the south-southwest; all streams in the watershed ultimately drain into the Ohio River.

The Upper Great Miami watershed is in the Till Plains section of the Central Lowlands Physiographic Province. Glaciation and subsequent erosion produced a flat to gently rolling land surface that is cut by steep-walled river valleys of low to moderate relief. In the southernmost areas, glacial cover is thin and erosion of the less resistant shales has produced a more dissected, hilly terrain of higher stream density. Average annual precipitation in the study unit ranges from 35 to 43 inches and increases towards the south; about one-third of the precipitation becomes surface runoff. Average annual air temperature ranges from 51° Fahrenheit in the north to 54° in the south. Average snowfall in the study unit is 20 to 30 inches per year.

Polluted runoff from both rural and urban land, development close to stream channels and modifications to the stream channel contribute to the majority of water quality concerns in the watershed.
