    So great that in the USA you are removing so many dams.

    I saw the barge and dredge crane docked on the south shore of the reservoir back in October or November. I wondered what is was there for,
    now I know. Thanks! I'm looking forward to more of these interesting videos.

    Thank you, very interesting. Good explanation of the downward angled drain and extension. This deconstruction project is very interesting and it sure seems well thought out from afar. I wonder if the Army Corps of Engineers is watching this with great interest. That would be funny if the tip clogged and the vent stayed open. That sediment dump inside the curtain should add a little silty soil to the old Ward ranch there on that bench. That bench extends south from the headlands just west of Beaver Creek towards the big cove on Patricia Ave. The people who live there will have the river right in front of them, with a meadow on the other side, on the inside of a U-Bend rising up into that bench.
    I think the part of this deconstruction that naturally seems the most interesting is the blowing itself. I'm sure that the pros know what they're doing but idiots like me wonder how that last blast can be done safely and with confidence of success at the same time. Prior blasting was by predrill and filling the holes with explosive apparently, and those blasts took out 6-10 feet of material per drill-blast cycle. So who gets to drill the last 10-12 feet that's left and how can you be sure that it will remove that much material, that the material will not clog the pipe, that the railroad-rail rebar won't still require cutting, etc.? I have done enough demo to know that one stupid nail will hold a whole huge structure together, and John Boyle (or whoever made decisions like using RR rail for rebar--it was before Engineer Schussler) seemed like the kind of guy to use screws in place of nails. Because presumably if it doesn't succeed it won't be safe to go back in there again. I guess they're going to do a much larger blast for the last one, and maybe the pre-drilling will be done by robot? I sure hope they have a cold beer ready for the guys who go in there for the final prep work.

      Gotta say, I'd be real nervous going in that tunnel for the last few drill and blasts cycles before they stop at the last 10 feet. Also kept thinking about that movie, "The Dambusters." Has the final blast to open the tunnel taken place yet?

    What was done with all the trash fish in the lake ? Just dump them down the river to feast on small trout and salmon fry ?

      @@thehornetsnestforge1269 those upper lakes are full of bass, perch, crappie, sunfish, catfish.
      I called the game department in Sacramento 3 years ago and asked what is going to be done with those fish.
      They will be flushed into the lower river.
      They will eat small salmon and steelhead fry.
      Example: the Columbia River is infested with bass and walleye and pike minnow, squaw fish. They devastate any small migratory fish. In the Columbia, they barge the fish down past Bonneville dam.
      I frequently fish the upper Klamath below Iron Gate. I already have caught perch in the river while trout fishing.
      Nobody took this into account.

      @@jesse75 yes they have . I worked on the watershed crews and salmon surveys many times . Squa fish yes very bad but haven't seen a report o but I haven't seen any data saying they are in the lake . I understand how detrimental this can be but your forgetting how warm the damn reservoir water is

      @@thehornetsnestforge1269 it would be great if the cold water of winter would kill off the spiny ray fish if they get into the river. But it won't.
      I've caught the squaw fish in the Shasta Lake, but never caught any in the lake behind Iron Gate. Columbia River is infested with them and so is the lower Yakima River. Lake Chelan is also infested.
      Never caught any squaw in the Klamath since fishing the river since 1977.
      Hope they never get in there.
      I have caught perch and catfish in the river. Caught a catfish down near Weitchpec. Wondered what the hell is that fish doing down here.
      So far only Perch in the upper river.
      Can't explain why, but the half pounders have always been in good supply.
      This last summer and fall especially.
      When people are counting redds and spawning fish, what are the meanings of the different plastic tapes and colors and stripes hanging in trees ?

      Most of those fish will be washed into the ocean during high flows. They do not have the strength to overcome the current. The Columbia River above Bonneville dam is very slow moving. Basically all of the river is lakes.@@jesse75
