Coastal plain estuary
Drowned river mouth
Land reclamation
Salinity vacillates with the tides as water incessantly circulates into and out of the estuary.
“Jasper bordered the northeast side of the basin where dolphins, gators, minks, otters, and every manner of waterfowl and shore bird prospered from the daily six-foot inflow and outflow of saltwater, freshwater, and brackish water that rose and fell on cue like the sun itself.” – Beth Webb Hart
