I used danforth to tie up at the sandbar in wisconsin. worked great. sandy bottom. just have to get out and step on it a little with feet to get it to set properly but when anchoring at the sandbar we were only in 4ft of water at most.
back home we never anchored as the reservoir banks were too steep to get anything to hold. have not tried at mead as no anchor on current boat and not really a fan of some of the desert dwellers that live off the beach so we just find a wide open spot and drift
