Pat,
I agree with Bill, Rainman and others. Willows won't die underwater unless they are helped along. I love the idea of them being living, underwater structure for the fish. So long as they don't spread too much to the banks and dam. I kill my willows and use alternate structure. To be clear, I have no experience with willows rooted in more than a few inches of water. My fear of invasion is what motivates me
