Yes, the swirl cage is a shaped concrete cage with curved walls, having small steel sliding windows around the periphery. These windows, many many feet below the surface, hold back the whole damn lake. When they open the water enters at an angle with great force, driving the vertical water turbine and the generator above it. If those widows opened when you were in there, even without a turbine in place, you wouldn't stand a snowball's chance it hell.
Everything is interesting... look closer.
