| Andy Michel posted Borrowing McNary Navigation Lock Stoplogs at Ice Harbor Tri-City Herald February 27th, 1968 Jim Duffus: On the original locks at the Panama Canal all miter gates were interchangeable with the exception of the sea gates at Miraflores which were longer because of the Pacific tides. Caissons were sunk for locks overhaul and they were moored in the freshwater lake and taken to the locks by tug when ever needed. Andy Michel: Jim Duffus Flexibility is the key! |
I didn't know about "nitrogen supersaturation." This article is old. I wonder how much of these modifications had been done.

| Andy Michel posted Flip Lips & Slotted Gates Tri-City Herald March 12th, 1972 Neil Jacobson: They installed aggressive flip lips on the spillway at CJ and it did make a difference plus a spectacular display when spilling. [Unfortunately, I don't know which dam "CJ" stand for.] |

This article applies to all of the big Northwest dams, so I'll put it in this in my news-only notes.

| Andy Michel posted Luck important in power generation Tri-City Herald June 13th, 1975 Delta Mike: Could be a sectional view of my dam also. Big Bend in South Dakota. Mike Kluth: Delta Mike I thought that the Missouri river Dams had Francis turbines. Delta Mike: Mike Kluth Big Bend is 3 blade, fixed pitch Kaplan turbines. We are very low head, typically 70' max. Mike Kluth: At the time of the article the 600 & 700mw Grand Coulee Third powerhouse units were being built. Jake Silverdale: Back when visitors were allowed at the locks I had someone ask me, “How come all of the electricity is used out of the water at the next dam upstream?” 😟🤔 Leon Powell: Jake Silverdale had a guy at Broken Bow had a whole story to go with that. Said there was still some electricity left in it and that was why a chain link fence ran part way down to the state park. He could tell it with a straight face too! |
If they did install slotted gates, it was only temporary because they used the generation bays for generation in 1975.

Gordon Gann said that "Value Engineering Savings Ideas, did not take into consideration the long-term maintenance costs. |

Andy Michel posted two images with the comment: "Barging the Snake The Spokesman-Review January 3rd, 1999"
Dennis DeBruler: So why can the salmon get past the four dams on the Columbia River but not the four dams on the Snake River? They get too tired going up the ladders on the Columbia River dams?
Andy Michel: Dennis DeBruler We’ve really improved our fish passage. People have resorted to saying we’re killing whales because of the Snake River Dams now.
Neil Jacobson: It’s not about how many get thru it’s the leftist communist democrats that want them removed just because it’s their agenda.
