It sounds like it might be pretty nutrient-poor water. IF there is a high flow-through rate, it may be hard to fertilize effectively and maintain a good algal bloom. Feeding would still help to increase the volume of fish in the pond if this is true.

If you can swing it, maybe bringing in a trackhoe, etc. to deepen the water near the outside of the pond would increase the amount of deep water in reserve for when the level drops a lot.

Any wise Southern experience & advice, guys?
