**This post is text heavy. I won't be offended if you don't read it, I journaled it just as much for my own memory keeping as for sharing. **
On Monday, Memorial Day, we had a family day. We like to do things educational of sorts together as a family. We'd been hearing that tours for the season were beginning at Chief Joseph Dam Memorial Day. We decided it was just the thing for us.
Chief Joseph Dam (named after the famous Indain chief, Chief Joseph), is the second highest producer of hydroelectric power in our nation. It is second behind only Grand Coulee Dam (also in our backyard of sorts, both are less than 50 miles away). I know, you might be thinking "what about Hoover?" While it's true that Hoover Dam is a more graceful and beautiful dam, it is not the top producer of electricity. In fact, approx. 31% of all our nations hydroelectric power is generated in WA state.
We were the first people to arrive and after going through all the security. And as the time progressed, we proved to be the ONLY ones on the tour. Yeah!
I did a digital LO of the event. I wasn't able to take any pictures, so I had to get creative to remember all the details for the kids.

And because the kids were very well behaved and we are uber dorks....we got a very special (IMO) tour that lasted just short of 2 hours.
We've toured both Grand Coulee and Hoover Dams and this was by far the best tour we've ever had. Not because of the facts and figures give to us, but because we were able to get up close and personal. It was incredible!
First we took an electric cart past the powerhouse. It is over 2,000 feet long. Amazing. And because of the treaties with the Native Americans, they are allowed to fish from the overhang. It was pretty neat, although no one was fishing at the time.
We went to the spillway and were able to get right to the edge. Very rarely is water passed over the spillway because it is a "run of the river" dam. Meaning it isn't built to hold back a reservior, just to use the power of the water for electricity. The volume of the water coming through rarely exceeds the capabilities of the generators, thus vary rarely is water spilled over. It would be like throwing away money.
Then we went into the spillway structure and took an elevator to the bridge. We were able to stand at the spillway gates. They are AMAZINGLY huge. The whole structure is so big you just don't realize how big each piece is until you stand by it. They are close to 4 stories tall. Amazing.
We went back to the powerhouse then for the best part of the tour. First we watched a video. Nothing special there. But then, then we put on our hardhats and the excitement began!
They are replacing the turbines at the dam. And the process had just begun, but because it was Memorial Day, no one was working, so we were able to go onto the work floor. Once normal work resumes, it will be closed again to the public. We stood on top of an operating generator and felt the vibrations. It was really neat.
Then we went to the bottom of the generator and were able to touch the spinning shaft. Now, this isn't really the bottom, but it was the lowest part we could see. But then we went down more stairs and saw right above the turbine where the levers and gates control the amount of water coming through (thus controlling the amount of power produced).
We also went to one of the generators that was having the turbine replaced. The housing was open so we were able to see the stators. (That is the part that actually generates the electricity - it is very tightly wound copper wires that are on the outside of the casing. As the shaft spins rotor, somehow the electricity is created between the rotor and the stator coils - sorry I'm not good enough with all the terminology to explain it).
We were also able to touch the new turbine going in. We were the first (and maybe only) general public to touch it. And to think that it will soon be put in the generator for 25 or so years with no other general public being able to touch it).
We were able to walk farther into the belly of the powerhouse. It was louder and colder the farther down we went. The dam was built with beautiful 40s and 50s architecture and finishes. But it was interesting that every set of stairs we went down, the structure was less decorative and more utility.
The lowest level we went to was the level of the scroll casing. We were able to look into one of the empty scrollcasings where the turbine was being replaced. The old turbine was already out, so we couldn't see that, but it was really neat to see the empty circular shape that the water is ultimately funned through to power the turbine.
All in all, it was a fantastic tour. We greatly enjoyed it!
The worst part was that I wasn't able to take my camera into the buildings. I took a couple pictures of the outside, but even at that, I wasn't supposed to even have my camera. So it sat lonely on the cart while we toured. The only thing that would have made the day better was to take pictures.
The kids were both troopers. Cody soaked up every detail. He LOVEs this kind of thing. He's my little engineer. Aly was tough. It was lots of walking, lots of up and down stairs. We had no idea it'd be so physical. It was so different than any other dam tour we'd taken, but it was incredible!
Next time though, I'm wearing my running shoes, not my heels! LOL!!
