You guys certainly know your stuff. I got out their this weekend and starting raking it to the shore and using a pitchfork and scooping it up and putting it in the boat. Guess what, after about an hour of scooping I saw a yellow bloom sticking up out of the water. I spent 4 hours raking and getting this muck to shore and only saw 2 blooms. You guys nailed it as Bladderwort! I promise I couldn't believe my eyes as I have never seen a bloom anywhere before. Thanks for all the responses and dedication to my posting and helping me identify what I have in the pond. I believe I am going to leave a little for the fish to hide in.
