Here are a few shots from the Nisqually dam taken in 1927.

This excerpt is taken from the book Upper Nisqually Valley:

“The flow that was to be used for power generation was divereted into a 1,3000 foot settling canal, which removed silt from the water. Then the water flowed into a tunnel that was more than 2 miles long.

The gatehouse allowed the settling cannel to be flushed of the built-up silt. The flow then entered a nearly 2-mile-long tunnel on the south side of the Nisqually River.  The tunnel was from 10 to 12 feet tall and had cement lining on the floor and partially up the sides. 

Welsh coal miners were the contractors for the tunnel portion of the project.”

  1. Diane. Great job your doing with the History of the Eatonville Area.
    We just got a calender that you done at Ohop Grange the other day and are sure enjoying it with family, your doing it for a great cause, good job and keep up the good work.
    I sure enjoy your articles in the Dispatch also. History is sure more interesting to me then what is going on these days. Thank Rich

    1. Thanks so much! The website has been fun. I figured I’d put some information online each day, since that’s where most people go to find out things now. And people have shared some incredible pictures with me. My husband Chris laid out the calendar though. I’ll tell him you liked it. I thought it turned out pretty good too.

      I know you probably have a few interesting stories of days past yourself. 🙂 If you want to share, I’m all ears!
