Jacksonville
System Information
System Description
Most of the community's supply comes from groundwater, but Mauvaise Terre Lake supplies water during higher demand periods. Lake Jacksonville is used only to increase levels in Mauvaise Terre Lake during emergencies. A valve at the 11 mgd treatment plant lets in additional water from Mauvaise Terre Lake as needed.

Developments since 1989:
The city is considering dredging Mauvaise Terre Lake. The newly formed North Morgan County RWD connected to the system in 2007. Although groundwater access buffers the community from drought hardships, storage from Lake Jacksonville had to be released into Mauvaise Terre Lake during the 2005 drought.
