Today tillyjane and I went hiking at White River Falls State Park, on the advice of ramblin_phyl. It's a beautiful little park in a small canyon, which features an electric power plant built in 1901, expanded in 1910-1911, and abandoned probably sometime after WWII. The walk down to the power plant is a short, steepish trail with good footing in dry weather.
The impoundment pond is barely visible as a rectangular structure on the left edge of the aerial photo linked to above

More detail of the impoundment pond.
The control valve of the impoundment pond.
The powerhouse as seen from near the impoundment pond above the top of the falls.
This is part of the pipe which brought water down from the impoundment pond to the turbines.
Flood Control Structure and Valve Station
The spillway of the flood control structure is clearly visible in the upper third of the aerial photo linked to above
A flood control structure built in 1910 to keep the water pipe system from being overwhelmed by water coming down the ravine to the north. Visible in the right hand side of the picture is a valve station for controlling the main water feed to the turbines.
The powerhouse seen from atop the spillaway of the flood control structure. The valve station is on the right again.

Gear wheels atop the valve station.

The powerhouse is visible in the lower right section of the aerial photo linked to above
Another section of pipe, in the drop to the powerhouse. For reference, it's about 30 inches in diameter.
Just above the powerhouse.
More views of the powerhouse from above. The substantial hole in the roof at the north end was caused by a boulder dropping from above.
Detail from the same angle. Note the turbine bulking within.
Detail of the round windows.
The south end of the powerhouse, next to the White River.

As usual, more at the Flickr set.
