The one thing missing is a way to drain it. Easily solved with a pump\hose on it. But that looks like it would be a too heavy to pick up and dump. This is a tank that would probably work well as is in cooler rivers but for a lake you would want to hold cool water, keep it cool (insulate it), treat the water (salt) and add an air pump.
