| Water enters a collection box a few hundred feet upstream from the generator. The collection box reduces the sediment load and regulates the amount of water collected. The box is designed to insure that diversions remain well within environmentally allowable limits. | |

Water flows from the collection box through nearly 400 feet of 4-inch pipe. This pipe has taps for domestic water to the caretaker's cabin and to a hydrant for fire protection. The head is about 90 feet, so the pressure at the cabin and at the powerhouse is quite similar to most domestic water supplies provide. All the pipe was laid by hand, including digging all the trenches with hand tools. Engineering students sometimes envy forestry students for the amount of time that the latter spend in beautiful places, but when the forestry students carried pick and shovel and the engineers carried calculator and plans, the envy vanished. |
