My feed rates vary from 1 lb/acre in cold weather up to as much as 5/acre in warm weather. For most of the year 2-4 lbs/acre is what I feed, so we're in the same ballpark.

Of course, it also depends on the size of the pond and what's in it. A small, strictly catfish lake would get higher feed rates than a large lake feeding suppl. for bluegill.
