Buy a minnow trap or 2. Place them in various places in the pond, from shallow water to deeper water. Use the fish food as bait in the traps. Leave them in one place for at least 4 hrs before moving/checking them.

Only panic if you don't find anything in the traps.

I second sending the water to TAMU.
