Tracy,
Did you guys discuss flushing your water, or trying to add water shed to the pond? Is it time to think about a different area to build a pond where you do have better water prospects?
Seems to me that even if you get your pond corrected this year, it is going to be a battle. Rinse repeat, year after year with that pond location.
All that said, That is an interesting plan. How much food are you planning to throw each day?
