We are now standing on the grating above the sump. The sump runs the length of the generation plant. This is so far down that those stairs lead UP to the underside of the turbine wheel.At the head of the stairs, Brian Congiardo stands at an access hatch to the underside of the runner (turbine wheel).This shot is looking straight up inside the hatch, seeing the bottom edges of the curved blades where the water exits them. Note the metal is at least 1/2" thick! In the lower left section, you can see the "snout" of the hub. A top view of this was shown here.
