Help, I have a 1 acre lake that has some shore erosion, 'rats, and muddy water. I was hoping to clear up all three problems with one solution. I was thinking of putting gravel along the shore. I've been trapping the 'rats for the last year and a half but they keep coming back. Any suggestions on whether gravel is a good idea, what size of gravel, how thick, and how far down into the pond should it go?
