I found one more cc, about 2 lbs. floating this morning. I fished the bottom and also with a bobber (I only had worms), but there was only meager interest. I do see dozens of little fish following my hook with the worm on it, so the pond is not "empty". Where are the big fish? Did they all die? Or are they still down below?

Does anybody know where in Denton I could take a water sample to be tested properly and give suggestions on whether I should do anything? I worry that the rest of the fish are sick and if I don't do something, I'll be scooping up fish every day until they are all gone.

I know I'm obsessed at this point. I love the pretty pond, but healthy fish are more important!
