A color photo of the main penstock - From Wikipedia:
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills.
This photo shows the cast iron pipes, the wheels used to open/close the pipes, and two pieces of equipment shaped like partial wheels with a large, ridged bolt that appears to raise and lower a piece of equipment.
