Nearly 36 miles of the Withlacoochee River’s 110-mile length are protected as an Outstanding Florida Water within the Green Swamp Wilderness Preserve.

Rainwater drains across the surface to create the headwaters of four major rivers: the Withlacoochee, the Ocklawaha, the Hillsborough and the Peace.
Rainwater also percolates down through the soil to replenish the Floridan aquifer system, the primary source of drinking water for most Floridians.
