Back side of dam suggestions

[Dragonslayr]

I used to use a Cub Cadet gt1554 for the back side of the dam. I had weights rigged on back and front to heavily lean to one side. Worked better than you might imagine..

However, my house burned down with everything else I owned. Thought I'd ask how others might do it..
BTW, I might mention the neighbors fence is at the bottom, so going up or down the dam doesn't work..
