boasts a unique and vibrant network of waterways, where freshwater from the St. Johns River meets the saltwater of the Atlantic Ocean. This mixing of waters creates brackish environments, which are vital to the health of the ecosystem.
Jacksonville The St. Johns River is the longest river in Florida, flowing north for over 300 miles. As it nears the Atlantic Ocean, the river’s freshwater mixes with the saltwater, creating a brackish environment. This brackish water extends throughout the river’s estuary, which includes Jacksonville’s downtown waterfront and its surrounding areas.
Jacksonville The brackish waters of Jacksonville are home to a diverse array of plant and animal life. The salt marshes that line the riverbanks provide habitat for many species of fish, shelfish, and birds. The underwater grasses provide food and shelter for manatees, dolphins, and sea turtles.
The brackish waters also play an important role in Jacksonville’s economy. The city’s port is a major hub for international trade, and the river is used for commercial fishing and recreational boating.

However, the brackish waters of JackSonville face a number of challenges. Pollution from urban runoff and industrial discharge can harm aquatic life. Dredging and development can destroy important habitats. And climate change is causing sea levels to rise, which can inundate coastal areas and alter the salinity of the water. Despite these challenges, the city of Jacksonville and its partners are working to protect and restore the health of the brackish waters. Efforts are underway to reduce pollution, restore habitats, and plan for the impacts of climate change.
