At just over 300 miles from its headwaters in the Upper Basin marsh to its mouth northeast of
Jacksonville, the St. Johns is Florida’s longest river entirely within its borders. It is an amazing
river that literally defies description for depending on where one encounters this serpentine
waterway, it may be accurately characterized as an elongated estuary, a vast inland sea, an
intimate blackwater creek, a braided puzzle-like marsh or an engineered drainage canal. Of all
its myriad characteristics, it is this diversity that makes the St. Johns a paddling destination that,
in a more reasonable world, would certainly eclipse Orlando’s Walt Disney World as a Florida
attraction.
The St. Johns River originates in the Upper Basin Marsh in Indian River County. The
marsh drains northward via sheet flow and through numerous man-made channels constructed
for flood control purposes and maintained by the St. Johns River Water Management District. The river flows through a number of lakes along its entire course, and the Upper Basin reach is
no exception. Once the river forms a channel, the lakes are connected by this well-defined
riverbed. The river channel is typically shallow and meandering, and the banks are heavily
vegetated with marsh grasses, often too high to see over from the seat of a paddle craft. North of
Lake Poinsett, where the river forms the boundary between Brevard County to the east and
Orange County to the west, the river divides into a braided channel that changes with stage and
flow, and while it can be navigationally challenging, this portion of the river provides paddlers
with some of the most interesting and rewarding paddling available on the St. Johns. The
floodplain in this area is used for grazing cattle and horses, and it is not unusual to paddle
through herds of both standing knee-deep in the river channel or grazing the low shoreline
vegetation. The pasture-like floodplain vegetation and low elevation provide the paddler with
open uninterrupted vistas with outstanding viewing of wildlife and seasonal wildflowers. The
low floodplain soil provides solid footing and paddlers can often save time and distance or
remedy a wrong turn by portaging a short distance across the open marsh from one channel to
another before continuing to navigate the winding river.
