PAVEWAY-

I sent your twitter images to the Cahills to ask for any comment and am hoping to hear back. They were so nice at answering questions back during the dam crisis. I don't know if the addy is still current or if government goons got to them they way they got to Weiryone, alas. But I will let you know if I hear.

I did find this Cahill interview at PeakProsperity back in 2017. The thing is, I assume nothing at all has been done on this so it is still 100% relevant, and your two twitter images should be regarded as very alarming.

I think it was Bea who said you can't know what exactly is going on without piezometers measuring the flow of groundwater, and the Oroville ones all over that wet area are non functional. Were they ever replaced? The only way to understand that wet area is piezometers....so do we have new ones? I would think it would have been talked about if we did. Maybe they actually do work fine and DWR is lying to say they don't function now, to avoid dealing with it? Who knows.

There are additional issues involving the unwanted moving of water through the dam — the so-called "green spots". These are areas where water is migrating through the dam, probably through the indigenous soils adjacent to it. I've walked on these [at Oroville] and you can stick your foot down, and like your backyard after a torrential rain, water actually comes up into the footprint after you remove your foot. This is not a good situation. I believe there is a lot of movement of water through that dam, including at the structure itself that houses the gates that control the flow down the principal spillway.

There's nothing wrong with embankment dams in general, they're wonderful dams. But they rely on the mass of the earthen embankment itself to offset the forces that try to slide or rotate it into failure. When we see water migrating through a dam, it can potentially cause failure of the dam because it offsets the mass all that earth. Plus, there's a lot of river rock and sand in this embankment. River rock, as we all know, is round. Anyone can understand how a pile of round rocks, if the fines have been washed out from between them by water and the rocks then vibrated, for instance, by seismic activity, weakens the system. These concerns are very, very serious. I believe that this situation is occurring in multiple places across the Oroville dam — and yet this is simply not being discussed.

People are not happy with how CA runs the water systems. Surprise surprise. Interesting article.

[link to www.zerohedge.com (secure)]
 Quoting: Prayandprepare000


Some will be happy that they had the foresight to build rain water retention systems.

As Californians tally the damage from recent storms, some are taking stock of the rainwater captured by cisterns, catches, wells and underground basins — many built in recent years to provide relief to a state locked in decades of drought.

The banked rainwater is a rare bright spot from downpours that killed at least 20 people, crumbled hillsides and damaged thousands of homes.

Los Angeles County, which has 88 cities and 10 million people, collected enough water from the storms to supply roughly 800,000 people for a year, said Mark Pestrella, director of the Los Angeles County Public Works department.

In the four years since Californians approved a measure to invest hundreds of millions of dollars each year to build small and medium-sized infrastructure projects that collect rainwater, experts say progress has been gradual, but not insignificant.

Sometimes, these small projects don't have positive results.

This happened the day my wife was born. Her mother was in labor a few miles away in San Fernando.

They do.

Normally, they spin up a turbine for a few hours in the evenings. Likely to facilitate pumping demands.

2K outflow is more than one turbine, and 10 hours is longer than the norm. Trying to limit the elevation to 800?

Elevation 795. This is normally about where we would see the seepage beginning on the left side of the upper portion of the spillway.

Of course, the camera is unavailable.

 Quoting: Prayandprepare000


To be honest, P&P, the recent imagery isn't much different than Sentinel imagery from 2016. Minor changes in the green spot, but it's always been there - even at low reservoir levels - and has always been a concern by dam safety people.

DWR has consistently dismissed ANY concern about it as unwarranted and something to do with drainage from the left shoulder 'natural spring' on the dam face. They are convinced that 1) the Zone 2 fill next to the clayey core is dry (based on the few remaining piezometers), therefore 2) nothing is leaking through the impervious clayey core anywhere on the dam, including and especially at the green spot, and 3) nothing is leaking past the drain curtain into the Zone 3 fill of the downstream face, therefore 4) the green spot is superficial and does not indicate ANY internal seepage through the clayey core or past the drain curtain.

See slide 6 of their piezometer presentation from 2019 for those dam details:
[link to water.ca.gov (secure)]

DWR did install some additional piezometers in 2019-2020, but these had to do with concern about leakage through the (fractured/rotten) bedrock and grout curtain under the dam core and/or some of that leakage bypassing the drain and seepage collection system. They indicated that these piezometers showed nothing unusual and increased flow in the drain curtain/seepage collection system was normal (10 gallons per minute) and only increased during periods of significant precipitation on the dam irrespective of reservoir levels.

I think the Cahills were aware of the new piezometer project and results. That project addressed core/bedrock seepage but it didn't explain the geometry or uniformity of the phreatic surface on the downstream side of the dam during periods of high precipitation. So I imagine they would still have concerns, but nobody can do anything if DWR isn't interested in measuring those specific things.

Worse yet, there will be another earthquake in that region eventually that seriously rattles the dam. I'm not talking about a M2.1 during refilling, but a real California earthquake. Without a proper sensor network on the downstream side, DWR will not be able to explain why or where damage may have occurred if it does. They can only say that damage did occur by observing increased flows in the drainage and seepage collection system. Big deal - that won't be of much help if you have no idea where the damage is located. They'll be forced to install even more piezometers or drill new inspection borings... providing they have the ability and resources after a significant earthquake. I seriously doubt that - DWR will be paralyzed if they have to deal with multiple dam/canal/levee emergencies all over the state at once, and Kiewit isn't going to chopper in to fix anything on time or under budget. The immediate cure is to drain the reservoir if damage occurs, but below 815' they'll have to rely entirely on the hydro plant or the tiny river outlet to drain it, which will take weeks. And good luck with that if the hydro plant is damaged or the downstream channel is plugged. Or if that happens during winter/spring rainy season.

Point is DWR is winging it and repeatedly saying the green spot poses no immediate danger (which is probably true). But it exposes their general ineptitude for operating and maintaining that dam - and their proclivity for doing it on the cheap or delaying it as long as possible AND doing it in secret - because 200K downstream victims are disposable people that don't need to know DWR's critical infrastructure secrets. You might be terrorists! The 'experts' said everything is OK. Trust the government - they got your back.

One earthquake is all it will take to dissolve their PR-fueled illusion of a "perfectly safe and well-maintained dam." Hell, another swipe of an atmospheric river this year might do the trick, too. It really doesn't matter - DWR will cry that it's a one-in-ten-billion year event that nobody on earth could have possibly predicted. Nothing will ever be their fault. Fukushima/TEPCO all over again. Oh, and could FEMA please send another $50 billion federal clown-bucks so they can rebuild all their crappy water infrastructure. This is so... predictable.
