Wow those are some steep sides, I can see the clay sloughing off. I have a pond with some sides that are nearly 1:1, and when I drained and seined it the same thing happened.

If you are convinced your fish are all dead, I'd refill and if your turbidity persists contact Rex or Rainman from the forum and have him come down and perform an alum treatment. If there is any water left I'd treat it all with Hydrated Lime to spike the PH to 11 and ensure all fish are dead before refilling.

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
