When I pump creek water into my pond, I direct the flow at an angle, so it circulates all the way around the 1/4 acre oval pond. I get about 55 to 60 GPM, so it creates a gentle current in most of the pond, and a fast current near the discharge. The CC seem to congregate a way out from the discharge, where the current is mild, while the FHM like to almost swim right into the discharge.
