It's amazing what can be done when the .gov let's people get to it and do their job. I can believe it's been seven months, if a read every response and have shown the albums full of pics to others. I still become amazed at the true size of this project, I would love to visit this site one day and see the true size in person. On that bottom photo in my last post, those little black dots on the lower spillway are work men. The bottom to top is 1000 yd, and north to south, or wall to wall, is 180ft / 60 yards wide, wider than a 6 lane in each direction interstate, or the max effective/accurate range of a bespoke handgun in a great shooter's hand. I dearly hope that once they are finished-finshed next year, that their emergency funds allotted for a GPR unit that is going to be towed over every square inch of concrete each spring when things dry off. I also hope the logs for the new sub-spillway drainage system are networked for remote monitoring. I can sadly see them falling back to old lazy and cheap habits in 3 years, once the microscope is no longer on them, either the governor won't fund them fully, or the director isn't using all the money for emergencies instead of preventative maintenance. |

They are getting rain and predicting more rain. For the first time since "drought", all the other dams are going into the wet season at a reasonable level as well.
11/05/2017 09:00692.17 ft elevation, 1195855 Acre Feet Stored, 4463kcfs Outflow, with only 1773 kcfs inflow currently. Flood control reservoirs should go into wet season at 2/3 to 3/4 of capacity (depending on long term forecast) with 5% for 'didn't expect that, ever'. In the past, they've all gone in at 80%+, so the lowering of Shasta and all the others is a good sign that heads are being removed at least partially from asses. Spillway Structure to be rebuilt in spring (base concrete, anyway) is at 813ft Elevation, ideally, they should stay dry instead of waiting a month for area to dry, since there is a LOT of water between 1.2m AF and 2.3m AF, with the ability to use 25k AF/day with all turbines running. Here's the quick table again since it was lost on earlier pages: 1006922 665.00 1040004 670.00 1073826 675.00 1108408 680.00 1179916 690.00 <current elevation is 692'> 1216871 695.00 1254630 700.00 1293191 705.00 1332544 710.00 1372704 715.00 1413683 720.00 1455498 725.00 1498161 730.00 1541693 735.00 <-- 736 ft "Drought, Never be full again!" level on 11/5/2016 1 year ago, leading to this spring's showing symptoms of no maintenance 1586084 740.00 1631365 745.00 1677549 750.00 1724650 755.00 50% Full 1772690 760.00 1821617 765.00 1871510 770.00 1922375 775.00 1974236 780.00 2027099 785.00 2080968 790.00 66% Full 2135848 795.00 2191746 800.00 2248665 805.00 2306612 810.00 <Spillway Structure is at 813ft, hopefully keep dry this season> 2365592 815.00 2425570 820.00 2486672 825.00 2548846 830.00 75% Full 2612099 835.00 2676450 840.00 2741845 845.00 2808351 850.00 2875981 855.00 2944749 860.00 3014668 865.00 3085752 870.00 3158015 875.00 3231450 880.00 3306128 885.00 3382033 890.00 3459177 895.00 3537580 900.00 ft <Overflow at 901ft - February 2017 > |

There's absolutely no reason to fill it up just so they can dump it over the spillway instead of having used it to generate power. It sort of defeats the purpose of the dam when they do that, since the springs when they use the spillway (almost half) end up causing large downstream fluctuations, vs. the steady outflow they can get by using it as it was designed to be used. The wanting it full all year, every drop of water is precious way of management puts the dams under undue stress. Combine that extra stress with only the simplest/cheapest maintenance done for decades, and anything will fail, no matter how it was designed. |

From looking at the lower spillway live cam, it appears that the lower access bridge across the canyon is already starting to collapse. That would be the one that is mid way up the reinforced concrete section on the right. I suspected that the temp roads over the canyon may get damaged or washed out by the rain, but didn't expect it to happen so fast. Looks like they finished up on the spillway just in time.
Rather curious about the plans as the roads collapse and material washes into the river. Perhaps dredge as necessary during the winter months so they can keep river water levels low enough to use the power plant and bypass line for level control? |

I think this is the remaining gorge that the emergency spillway carved. Weren't there plans to have it filled in or something in Phase I / This year? Seems to just be the common runoff point for the spillway hillside outside the spillway ramp itself.

My only guess for that would have been to give a bit more clearance so a crane could lift a large/clumsy item over the wall easier, but since there's no road on the other side of the gap, I have no clue. It's an interetsing thing to have noted though, so kudos to whoever found it! |

At some point they built a different form.
From Oct 26th I believe  Attached FileThat part of the old diffuser (or what ever it is called) was pretty heavily damaged. Maybe they decided that there was not a good way to tie into it and just left a gap. Any water that overflowed through there would bypass the end of the spillway and to directly to the river.

I've seen the same thing happen at other work sites where remote monitoring is being used. There will always be someone being very vocal, commenting on every action, and deciding that everyone on the project is a doing something wrong. They're also the ones submitting their "coaching reports" and saying how much everyone appreciated their advice. It's one of the times when you just smile, nod your head, and move on. |
