There were another 120 negatives in the Liberty Dam collection. I scanned all of those. The file drawer also contained about 250 negatives, building the Ashburton Filtration Plant. Fortunately I had previously scanned these from photo albums – all but 22 that were missing from those albums. I hope when and if they get someone to take my place doing this archiving, they will be able to put all like albums/negatives/photos together in proper groups. I am not sure I will have the time. As it has been, I just scanned and documented them as I pulled them from shelves, dusted them off, documented and then packed them back up for storage.
Here are some more from Liberty Dam 9/1/1952 – 10/6/1953 (The next drawer has a bunch of negatives from building the bridges across the reservoir).
Another accident. A truck went off the bridge and is being hoisted out by crane.
Man, I wish I was there with my kayak! This is the relief opening so the contractor can start building on the opposite side of the river.
Images 125 through about 180, the negatives all have this overexposed spot on the left hand side. Some I trimmed but others I was not able to.
This one was strong enough to wipe out the coffer dam, but the men are steadily working on the right, placing forms for this portion of the dam.
While one crew is placing the foundation to the west, the east gang continues to raise the elevation of the dam.
Still working against the floods and snow.
Meanwhile, upstream a ways, the intake structure is almost done. A couple things about this photo – how tall the structure is and how deep the water will be at this point of the reservoir. Also, I’m not sure why they didn’t grub, remove the plant growth that will eventually be underwater?
After a few months, the base areas of the dam are completed. Not seen here, underwater, is a relief opening (Kayak hole). Another flood has happened and the water has risen.
Wow – kind of looks like Conowingo Dam on a small scale. I wonder how much sediment is in this reservoir, against the face of this dam?? Since 1956??
The water just rages through. eventually the relief opening will be closed and water will either go over the top of the dam or through the intake structure and head to the Ashburton Filters.
Putting the finishing touches on the intake structure.
Almost done. I have posted on another blog (or Facebook) the finished dam and that engineers were wagering on when the reservoir would fill and the dam would crest? The Liberty Reservoir reached the crest point of four hundred and twenty feet on February 6, 1956, approximately nineteen months after the filling of the reservoir began on July 22, 1954
