Drought hits Briar Creek

Algae and icky ooze clog what little flow remains in Briar Creek near Merry Oaks on Aug. 18.
It's unclear whether the lowness and slowness of the creek are just from the drought. It's possible Charlotte Country Club is using creek water for irrigation; the club built a retaining pond after another recent dry summer, and it's working on renovations for a future event.
Are there any rules or laws about how much water private enterprises can take from public waters? Should there be?
