SK63, you're dead on with DNR. Same with any DFW in our area. Trees near a dam will cause havoc as the head pressure mount, finding a leaching potential area/areas via the roots, and the dam is compromised.
Trees/brushes must be removed at minimal of 100ft from any dam structure.
However, when you are removing trees, make sure to remove everything..I mean everything, especially the roots. Jwann is right about posting the photos. We need to make sure we give you proper advice before you start removing trees, or you'll lose more than just a dam and some trees.
