The dam and old generating station once provided a source of power for the city of Mammoth Spring. Early nineteenth century settlers in the Mammoth Spring area formed a village known as "Head of the River." The town prospered due to an early grist mill powered by the spring's water. In 1886, the Frisco Railroad built lines into the area and constructed one of its first train depots in the town, now called Mammoth Spring. With the coming of the rail-road and the addition of the dam by the Mammoth Spring Milling Company (wheat mill) in the 1880's, the town flourished. The Arkansas-Missouri Power Company bought rights to the dam in 1925 and constructed a hydroelectric plant which provided electricity to the area until 1972. In 1957, legislation established Mammoth Spring State Park.
Mammoth Spring flows at an average rate of 9.78 million gallons per hour with a constant water temperature of 58x Fahrenheit.
