I am going to say the opposite. Fill it full of water and then use a flexable syphon pipe to suction the muck over the dam and down to a place you can deal with it.

Water can move just about anything. I would use it like a vacuum. Just know you need a place below the dam to settle the muck out and then it can be dealt with on your schedule.
