Take a kayaking trip on the lake. Just be sure to not use a whitewater kayak to do that. I had a wonderful idea to paddle down the whitewater river until it dumped into the lake. Only one problem, I didn't realize that I was going to be paddling 2 miles in the flat lake water with a flat bottom white water kayak. I believe I completed an Olympic workout after I made it back to the truck.
Did you know the best enders are located in the smallest looking of rushing white water? I find the place where the water is rushing between the rocks without many air bubbles and drop the nose of my kayak in where the water is rushing through that space. When I do this almost always the pressure of the water will push the boat down to where I go from sitting in the boat to standing on the foot pegs or bulk head foot rest. Once the kayak is vertical in the water, I take my paddle and make a sweep through the water to make the boat spin.
