I think some are confused between retention pond (man made) and natural pond spring feed or sinkhole depression that fills up with water.

Retention ponds hold water over flow and may or may not have water all time, most likely they go dry every 4 or 5 years or so due to drought conditions. If developers made pond it’s retention pond.
You can bet they are thinking right now about raising water rated like they did 5 or years ago when like this year it didn’t hardly rain till June. After about 3 weeks of elevated water rates it started to rain and by end all July all ponds was over flowing. But higher rated didn’t come back down till end of October.
