liquidsquid, sounds like a plan except for the big bass. They'll just slurp up my desired forage fish by the thousands. Ducks will visit briefly on their migration south and won't be a problem. The turtles are manageable. The crawfish have gone into full burrowing mode since the water temps have fallen and I'm thinking I will pour an ounce or two of ag strength vinegar into each burrow I can find and then, along the bank of the dam, pour Sacrete into each burrow to counteract the effects the burrowing has had on the structural integrity of the dam. I think this burrow treatment will throw a real kink into the reproduction of the crawfish and I'll start trapping them out again in the spring.
The part of your reply I'm most interested in and completely clueless about is what and how and when to plant when I've reached a good condition for plants to grow. Never planted a plant in water in my life. Are there resources available where I can find out what are desirable plants and how to propagate them?
Coincidentally, I just saw a very thin layer of pond scum in the shallow water where I've placed brush piles for cover for the forage fish. Is this algae? Should I be concerned or encouraged that some plant life is appearing?
