I like the idea of variable cover. Any suggestions I could practically execute without too much time and money invested?
I was just thinking of fluffy cover that would grab your fish hooks like cedar trees or your tubing trees with some weed fabric to enhance periphyton growth.
Do you have a small boat at your pond? I was speculating that you could put on just enough ballast to sink your variable cover, and then pull it up when it became fishing season.
If you don't have a boat, then you could drag it to shore (or to very shallow water) when you wanted it out of the way. However, re-installing cover that you dragged out would be difficult unless you had a boat, or sufficient ice cover to walk it back out to its correct location during winter.
