machine hall ![click to hear](/images/speaker.jpg)
Area that houses the generator units used to produce electricity.
power plant ![click to hear](/images/speaker.jpg)
Plant that uses an energy source, here water, and converts it into electricity.
diversion tunnel ![click to hear](/images/speaker.jpg)
Underground conduit that diverts water during construction.
training wall ![click to hear](/images/speaker.jpg)
Wall that separates the spillway chutes; it is used to direct the water flow.

Inclined surface along which discharged water flows out.
afterbay ![click to hear](/images/speaker.jpg)
Area of the watercourse where water is discharged after passing through the turbines.
bushing ![click to hear](/images/speaker.jpg)
Device that allows the conductor to pass through the wall of the transformer and separates it from the latter.

Channel that discharges excess water from the reservoir during flooding to avoid submerging the dam.
top of dam ![click to hear](/images/speaker.jpg)
Upper part of the dam; it rises above the water level of the reservoir by several yards.
headbay ![click to hear](/images/speaker.jpg)
Part of the reservoir immediately in front of the dam where the current originates.
penstock ![click to hear](/images/speaker.jpg)
