THE MAD RIVER WATERSHED

THE MIAMI VALLEY BURIED AQUIFER

The largest ground water source in Clark County is the Mad River Buried Valley Aquifer. This aquifer contains outwash sediments deposited by water rushing from the melting glacial ice. Well-sorted sand and gravel deposits help make buried valley aquifers the most productive aquifers of the basin and some of the most productive in the world.
