My pond was finished May of 2005. As of today, the deepest place at the dam is about 6 feet, there is about another 12 feet to go before the pond will be completely full. This past weekend I noticed what I am sure is small cattails coming up all around the pond, they are about 12 to 24 inches long. I was very dissapointed as I am not a fan of cattails because I have seen them take a pond over. My questions is; should I try and spray the cattails now with some kind of chemical or will they die out when the pond eventually fills with another 12 feet of water
over them?
