Thanks for the quick response and welcome to the forum. I have not checked the entire pond for depth but did put a tape measure close to the dam and the depth was similar to when it was built. I haven't treated the water shield ever and it has pretty much taken over along with the cattails. I'm thinking on using navigate to kill the water shield in the next week or 2 and clearcast for the cattails. Any +/- to that strategy? It was basically cow pasture 35 years ago and a dozer was used mostly for the dam and sheeps foot roller. Any and all advice is appreciated. Thanks for your time.
