Doubtful the lake level changes rapidly.. If it's not too deep how about attaching 3 or four adjustable stifflegs and deploy them when needed (ie extend them to the bottom to support the 'float' for the time of use.. retract them when you're away. You could adjust to suit the depth at the time (again, assuming it's not too deep)
