"Maybe Ill spray myself with gaotr repellant and go snorkeling to pull out a bunch of the debris."
I can't recall if you have a boat? If so, you can clear a lot of debris while you remain on the surface using a grass rake (or similar item) lashed to an extra pole.
As I recall, you also have heavy vegetation on your banks. My advice would be to clear some spots on the banks for your casting stations. Then clear some channels in the pond for a few casting directions from each station. If your casting accuracy is a 5' target width at the end of the cast, then clear 6' wide channels.
As you get better with your Texas rig, you can throw one up the middle of the channel. If you don't get a bite, then start tickling through the sticks at the edges of your channels on your subsequent casts.
Even better will be the times the LMB are hitting your topwater lures. You can cast into the channels for little kids, and then let them do the retrieve. Hopefully, the result will be huge grins!
