Snoqualmie Falls

An old waterwheel

Metering panels

The generator room, notice the lit up "1898" display at the end of the room


These meter displays were hand drawn

Powerhouse #1, is completely underground

The turbine design




Communication wiring

The dam, which is really a retaining wall to keep the water level above the intakes

The edge of the falls

The original machine shop building

2000 V bus, much lower than modern installations

230 kV Transmission Switch and Line Intersections

Starting from the left: 115 kV with 12.5 kV underbuilt, 2-230 kV lines on the steel poles, and old 55 kV lines used as 12.5 kV distribution

One of the 230 kV lines dead-ends, the other heads into this switch

Up close of the switch, old style 230 kV

From the switch, the line intersects the line running across the photo

Heading along steel lattice towers
