About this city
Mammoth Spring is a unique coastal-style scenic river city located on the Missouri border in far northern Arkansas, famous for housing one of the world's largest water springs. The town formed directly around this massive subterranean geological wonder, which flows at an astonishing average rate of 9.78 million gallons per hour, creating a giant 10-acre lake. Mammoth Spring expertly preserves its turn-of-the-century railroad heritage and historic mills, serving as a primary subarctic-temperature cold-water trout fishing paradise.
