Help Please!!!

I ride on Smith Lake and the water rises and falls a lot since they use the water to generate power. I was wondering if anyone has any ideas/plans for a slider that will go up and down with the water and stay stable enough to hit.

Thanks

Floating slider with a chain. If the water goes up and down 10 feet the put a 15 lbs weight 10 feet up the chain with a normal HUGE ancor to hold it.

When the water goes down the 15 lbs weight will hit the ground and hold it there
