The St. Johns River is part of one of the most extensive river systems in Florida. It is a major waterway in the northeastern part of the state and stretches for 310 miles from its headwaters at the St. Johns Marsh to its mouth at the Atlantic Ocean. The river is navigable for about 160 miles, making it an important transportation route for commercial vessels and recreational boaters.

The St. Johns River flows north, which is unusual for a river in the United States. This unique characteristic is due to the underground Floridan Aquifer, which acts as a natural conduit for water flow. The river receives water from various tributaries, including the Econlockhatchee River, the Wekiva River, and the Ocklawaha River.

The water flow in the St. Johns River is influenced by natural factors such as rainfall and tides. The river’s flow is typically slow, averaging about 3.4 cubic feet per second, but can increase significantly during periods of heavy rain. Tidal influences are more pronounced in the lower reaches of the river, where saltwater intrusion occurs during high tides.

The St. Johns River is also an important source of freshwater for local communities and serves as a habitat for various species of fish, birds, and wildlife. Efforts have been made to protect and restore the river’s ecosystem, including the implementation of water quality monitoring programs and the establishment of wildlife management areas along its banks.
