C losed oxbows within the Hendry County boundaries are being studied in this project. According to the study that was conducted in the fall of 1996, closed oxbows tend to have many differences from the open oxbows as noted by the observations. One difference is that the closed oxbows have quite a bit more vegetation located within them. Another is that there appears to be more decaying sediment within the oxbow causing bubbles that present a fowl sulfur aroma due to hydrogen sulfide rising to the surface of the water. The first, Udifluvents, consists of spoil material that was piled up along the Caloosahatchee River when the waterway was dredged.
Udifluvent soil has very dark gray fine sand.
Its surface layer is about 25 inches thick. Udifluvent's composition will vary from place to place and from layer to layer because it is not natural soil. Udifluvent soil could be useful for one cause in one location but in another location it may not be useful for the same purpose. Udifluvent soil is a common type of soil to build homes on and other buildings. The other type of soil near this oxbow is Chobee.
