California's Lake Oroville Main Spillway Severely Damaged/Eroded. Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed

Excellent. Bullet dodged, carry on.

I would say "duh" but that would just be crass.

How about we have never "deconed" a flooded area before????

all flood waters have sewerage in it. since when do
the authorities tell the People?

Why did you use two? Did you do this in two locations i.e. one for main panel and one for sub panel? or two in same location i.e. daisy chained together to main panel?

Uhhhhh totally missed the point. Sorry dudette. They have never deconed a flood. I have been through many. No decon.

Again what the others asked and it begs to answered sooo badly: why the fuck are they having to decon the flood zone?

Due to the recommendations in the latest NEC up to that point. NEC stated two 1/2" rods 6' apart for a main service. I did two 5/8" rods, bonded together, even though the county had not yet adopted the regs. I just didn't want to get into a 'he said, she said' with the inspector.

Sometimes, people get caught up in the process, due to the cost of a few $$. I didn't want that to be an issue.

But likely accurate.

I did not know they wanted two, interesting..... I see a lot of people adding a ground rod to there system and not have them bonded together..... i.e. by the hot tub in back yard..... ground loop issues can happen.

Thank you.

BUMP...Storms in UK, my internet keeps going zero :(

I was under 6 foot of water last year..thousands of homes flooded, seems its being controled

bastids ..but sadly..nothing we can do :(

Beyond accurate. Who would care about the rules at this point? They all know they are either going to jail or going to ummmm sued to death by someone's living relatives. :) bring the lawyers

The FCC is very picky about that.
Call and report them.
The FCC will jump at the chance to fine someone.
Have you checked the local Volunteer frequency's?
In my area they have a channel for in department and another channel for what they call mutual aid. that is used when several departments or agencies are operating in the area. During the Gatlinburg fires I heard more on those frequencies than all other channels all the police and state people used them.

DO you have a scanner that has a limit search? If you do set it up to scan a range and listen for 5 mins and if nothing then go to the next range.

Considering the measures which they have already gone to, to keep the public in the dark, I think that it's only reasonable to assume that they will continue to do so.

It's possible they're running blue dot or similar frequencies at lawful levels (1 watt and under IIRC) to surpass licensing regs on 2 meter frequencies. These power levels may be why they had signal issues not too long ago...

Military and Government comms. are probably out of this World by now.
they're probly working in the Tera Hertz Bands for all we know.

I had a ground loop issue on my 10 meter radio antenna that took almost two months to troubleshoot... turned out to be a bad solder connection on a transformer ground connection

Very true... bit when they were having signal issues under half a mile... they're not using that technology.

I would not be at all surprised, especially if the assigned frequencies are dead air. Or could they be borrowing the frequency of another agency, say FEMA?

yes. i'm wrong Tera Hertz Radio Waves are fascinating,
but their characteristics don't make them conducive to
voice com.

Not sure why it's mashing them all together like that.

That is a weird jump.

Something for diagramtards,
what was normal operation last year,
and where we are this year:

No new pics yet???

They DID lose another section of the spillway earlier this week.

The 'original' crater edge was three side drain sections down from the electric towers when they cut the flow a few weeks back for inspection. A couple of weeks ago another section went an they were only two side-drain sections away from the towers.

The latest DWR pictures include this one uploaded on Friday, the 24th of Feb., although the filename seems to suggest it was from Thursday, the 23rd. There is only one whole section remaining from the tower drain if you look at the picture. I would guess it dropped earlier this week when everyone noticed the plume changing (and DWR stopped publishing any other incriminating photos).

No idea if drain-to-drain section corresponds to any kind of real engineered section - I'm simply using them as a reference. The current edge is not straight across like it might be at a joint. The left side wall (looking down the spillway) is longer than the right side and the spillway floor on the left side has a longer, jagged edge jutting out maybe 20' or 30' further out than the right side.

There's probably better pictures out there showing the two- and three-drain sections intact, but this is one from the DWR site from back on Feb. 8th that kind of shows three full drain sections back to the tower. The fourth visible drain is higher than the tower.

The reservoir is getting low enough that they can cut the spillway flow way back (or completely stop it) by next week.

TropicalTidbits' GFS forecast model shows an inch or two of rain/snow on Monday night, but clear for the week otherwise. No need to panic... yet.

Maybe this picture was published here before,
maybe I missed it,

Nice to asses what is leaking.

Well, that theory didn't last long.

Mick West at Metabunk has a clear aerial shot of the spillway from overhead on Feb. 14th here:

The orange fence, portable lights and road are all in the same place as the DWR picture posted yesterday. If that was actually taken on the 23rd, then nothing has changed much as far as the spillway edge itself since the 14th. The perspective and the drains locations were confusing me, but the overhead shot on Metabunk looks like the DWR picture, so no further erosion of the spillway itself. Anything that's changed has been at the bottom or sides of the waterfall, not the spillway concrete itself.
