sullpond - Yes my numbers for fish production were based on feeding the fish pelleted food. Basically you are turning your pond into an aquaculture pond. Feeding fish in a captive situation for increased production. Fish numbers need to me monitored and adjusted according to your goals.

Get that second opinion reagarding your springs. The Soil & Water guy didn't give you an answer because he didn't know the answer. Get a person experienced with hydrology.
