The Wacissa River is a large, spring-fed stream located in south-central Jefferson County, Florida. Its headwaters are located about a mile south of the town of Wacissa, where the river emerges crystal clear from a group of large limestone springs. From its headsprings, the river flows approximately south through a broad cypress swamp before breaking into numerous braided channels which join the Aucilla River a few miles further south. The river is managed by the Florida Fish & Wildlife Conservation Commission as part of the Aucilla Wildlife Management Area, and has been declared an Outstanding Florida Waterway by the Florida Department of Environmental Protection.
