The 9.5 acre pond at Mammoth Spring. 70 feet below
the pond is the opening of the underground water passage. This tubular
cavern in the limestone is 15 feet high and 34 feet wide.
Mammoth Spring flows as much as nine million gallons of water per
hour. It is the tenth largest spring in the world.
Most water from Mammoth Spring originates in the rolling hills
of southern Missouri. Scientists have used dyes to trace the movement
of this underground water from points in southern Missouri to the
spring. Look how much comes via West Plains!
