Harrison Spring: One of the Largest in the Midwest (GM-13)
The amount of water the spring discharges varies greatly, but its minimum flow is more than 3 million gallons a day and increases to about 10 times that amount following heavy rains. Much of the spring water is diverted from 4 miles to the northeast; from the spring these waters flow southward about half a mile into the Blue River.
William Henry Harrison, governor of Indiana Territory from 1800 to 1812, constructed a gristmill and a sawmill just downstream from the spring in 1807. Harrison maintained a farm at the spring, and the area became known as Harrison Valley.
