About Palmetto Settling Area No 6

It impounds the Little Payne Creek near Fort Meade.
The dam stands 45 feet tall and stretches 15,840 feet across, creates a reservoir covering 278 acres, and has a maximum storage capacity of 12,500 acre-feet. Completed in 1973, the structure is well into its service life at over 50 years old.
