Texas715,
This pond should be in the range of 1/2 acre give or take. It is about 5 feet deep so that is one reason I think we would have a hard time with any fish making it through the winter.
Plus as that depth it may be reasonable to drain it toward the end of year to get Tilapia out.
If I were to make it a Tilapia pond how many should be stocked in this size pond?
