High Quality Content by WIKIPEDIA articles! 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 12 miles (19 km) 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.
