The emergency overflow is grass covered with taller field grasses that grow in a shallow layer of topsoil, and beneath that is clay and rock. It is not near as steep as the back side of the dam. The dam is about 30 to 40 feet thick at the full pool water level and the e. overflow is closer to 60 foot thick. The e.overflow can easily be mowed in any direction with a zero-turn, but only gets mowed once a year. I'd say it has a very strong chance of withstanding occasional use.
RAH, it sounds like we have a similar thing going on, except my near complete lack of vegetation...I'm still working on that. Thanks for joining the thread!
