Gee Creek

Map it!

A part of the Lake Jesup Watershed

Gee Creek flows northeasterly from Lake Kathryn to Lake Jesup, a distance of a little over 3.75 miles. It is heavily vegetated and access is very limited. This stream winds through a number of residential areas. Hardwood swamps are located in selected locations and hydric hammock wetlands are found in portions towards Lake Jesup.

The macroinvertebrate community found in Gee Creek reflects a healthy environment. The bioassessment tool employed to reveal this condition was FDEP's BioRecon. Despite the waterbody's urban setting, it has remained natural in most areas. There are many variables such as habitat, flow, and excess sand or silt smothering that contribute to the health of the macroinvertebrates here. Gee Creek provides the much needed habitats; aquatic vegetation, fallen tree branches, slightly undercut banks with delicate hair-like roots, and partially decayed leaf debris. These diverse substrates aid in protective cover and help supply food sources to these small organisms. More than 25% of the stream contains these desirable habitats. Another important factor aiding in food supply is water velocity. Gee Creek provides sufficient flow for these small invertebrates. This group of crustaceans, worms, mollusks, juvenile and adult insects thrives in this water body that contains shallow pools and minimal silt and sand smothering. Overall, the ecosystem in Gee Creek grants these macroinvertebrates, or water quality indicators, a favorable place to call home.
