The sidewall drains were never meant to flow at the rates that apparently became common and expected.
Significant flows from the service spillway outfalls were observed at the time of the first discharge
through the spillway, in 1969, as described in DSOD notes and a DWR report [10, 13, and 14]. The same report states that the high flows from the outfall are related to spillway discharge and that the “high flows from the spillway drains are mystifying but probably not dangerous as the chute is anchored.” The report also states that “inquiry to the designers regarding this aspect of performance would be in order.” The IFT was not able to locate any documents indicating that the designer(s) were consulted at that time. From the design documents, the IFT is confident that the intent of the underdrain system was to collect seepage from groundwater beneath the slab, and not to collect large amounts of leakage from flows in the spillway chute. Reports of flows from the spillway underdrain outfalls were sporadic and limited. From an evaluation of the available reports (see Appendix F1), there appear to have been several factors that affected drain flows when the gates were not discharging, and there were no clear patterns of how and why drain flows vary under these conditions. However, when the spillway was discharging, high drain flows consistently occurred, and the data indicate that the drain flows increased with increasing chute flow, though not necessarily proportionally. The IFT agrees with the initial 1969 conclusion that the high drain flows are principally attributable to leakage through cracks and joints in the service spillway chute slab. This was dramatically demonstrated during post-incident repair work in 2017, when water was observed flowing on the spillway chute from leakage with the gates closed. To facilitate repair work, sand bags were placed on the spillway chute to direct the leakage flow toward a narrow area near the left chute wall. When the sand bags were placed, drain outfalls on the right side, which had been flowing significantly, stopped flowing. |

Always good to see a new update by Juan. There are some other new videos out there but putting up with 20 minutes of video from the start of the failure to get a minute or less of new video or some photos isn't worth it. Not to mention he hideous music they'll have as soundtrack.

I'm cross posting from the impending Washington Landslide thread.
Quoted:
Update: We're starting to see some time lapse animations... (holy shit that's a big fucking bunch of material) https://www.seattletimes.com/seattle-news/science/dramatic-new-images-show-rattlesnake-ridge-slide-moving-over-time/ We know there's more than enough continual data since they made 3d prints of it at different stages. A compilation would make a knock your socks off animation and timetable of both the erosion, cleanup, and rebuilding. I wonder if somebody like Juan could give them a nudge to get their PR department on that.

Washington >>
While it has been assumed the federal government will pay 75 percent of the now-$870 million cost for repairing the Oroville Dam spillways, the agency that actually would allocate the money has been hedging on whether that is the case, according to two north state congressmen. A joint press release from Doug LaMalfa, R-Richvale, and John Garamendi, D-Fairfield, said the Federal Emergency Management Agency has been telling Congress it's uncertain whether FEMA has the authority to pay for the types of repairs being made. FEMA has stated it can't fund a project where the agency determines there was a "lack of maintenance," and can only provide reimbursements for work to bring facilities back to their "pre-disaster design," according to the release. "The Independent Forensic Team determined that Oroville Dam spillway's original design and inadequate maintenance contributed to the spillway failure nearly a year ago," said LaMalfa in the release. "Knowing that, what good would it do for FEMA to reimburse the state only to return the spillways to the same condition that played a role in causing the disaster in the first place?" More Here |

There were somewhat similar issues after Katrina. Buildings were destroyed, but were also completely substandard to begin with. The government would only rebuild to original, but original could never be built again since it was completely inadequate. Sort of like wrecking your 30 year old beater car and expecting to be reimbursed with a completely new car.
It was inadequate to begin with, you didn't take care of it, let it go to shit, and now expect us to get you a new one? Sorry, ain't gonna' happen. |
