The. St. Johns River is Florida’s longest river at 310 miles long. It is one of only a few rivers in the US that flow north and is one of the laziest rivers in the world.
With headwaters in saw grass marshes south of Melbourne in Indian River County, the St. Johns River flows into the Atlantic Ocean near Mayport in Duval County. The Wekiva River, the Econlockhatchee River, and the Ocklawaha River along with other tributaries flow into the St Johns River.
Twice a day, the incoming tide from the Atlantic Ocean causes the St.Johns River to reverse its current. When the water is low and/or the wind is blowing from the northeast, the reverse flow can extend 161 miles upstream and last for several days.
The reverse flow makes the St. John’s River more vulnerable to pollutants since they are not easily filtered.
For the St. Johns River and all rivers in Florida:
– Reduce fertilizers.
– Plant Florida native trees, shrubs, and wildflowers.
– Make sure your septic system is working properly
– Pick up dog poop. Don’t let it run down the storm drains.
Can you think of any other ways you can do your part to keep Florida’s water sources clean and safe for humans and wildlife?
