SPringsWatch: Rainbow River

This group is accepting new volunteers. Volunteers must have their own kayak, canoe, or paddleboard to participate.

Rainbow Springs consists of twelve named vents that discharge groundwater from the Floridan Aquifer System at a combined historic average discharge of more than 485 million gallons per day (MGD), making it one of the largest first magnitude spring systems in Florida. Rainbow Springs forms the headwaters of the Rainbow River, which is nearly 6 miles long and merges with the Withlacoochee River in Dunnellon, Marion County.
