Over the last 10 hours the reported increase in AF stored has been just 610 AF:

[link to cdec.water.ca.gov]

YET...if we calculate the difference between CFS inflows and CFS outflows during that same period, each hour by hour as follows:

OUT-------IN--Difference

9,522 10,668 +1146
9,448 10,417 +969
9,367 11,340 +1983
9,552 10,852 +1300
9,439 9,752 +313
9,591 9,752 +161
9,543 10,679 +1136
9,850 10,777 +927
9,724 9,660 -64
9,828 10,643 +825

That is an average hourly CFS differential of +869.6. That means a net increase of 869.6x60x60 cubic feet of water flowed in every hour for ten hours= 31,305,600 cubic feet added the past ten hours.

1 acre foot = 43,560 CF

31,305,600/43,560 = 719 acre feet (AF)

119 AF are thus leaking UNREPORTED, every ten hours, through other places...the main spillway gates, seeping under the spillway, etc... or about 12 acre feet per hour.

That's a LOT of leakage.

That was tremendous. Hadn't seen that one.

If anybody thinks it might be out of date and not worth watching or listening, think again. The majority of it is very pertinent.

Two things that struck me.....

One is that Cahill says the gates are so bad they probably can't handle outflows higher than 40,000. Now Folsom dam had the same exact kind of radial Tainter gates, and the gate failed at 40,000. A big part of that was corroded trunnion pins.
[link to www.usbr.gov (secure)]

Oroville had the same kind of corrosion in the past and I don't know what got fixed. Maybe aging gates like this are not safe past 40,000?

The other thing was that Cahill said they should have closed up the gates and taken a chunk out the Emergency SW weir and rebuilt a brand new spillway there. The only way to make it safe. They had two years and maybe it could have been done, but too late now. It was an interesting part of the presentation.

A lot more, give it a listen.

Now we all watch and wait.

719 acre feet when you are talking 3,150,000 acre feet is like a few drops in bucket.

A wind shift in a lake that size will move the measuring gauge up or down more than that amount of water added into the lake.

The surface area of Oroville Lake at the level it is now is somewhat over 16,000 acres. Adding 719 acre feet of wter to that amount of surface area raises the lake by .0449 of a foot, or about 1/2 inch. (719/16,000 = .0449 .... 12" x .0449 = .54 of an inch)

Even on a small farm pond with NO WIND pushing water from one end of the pond to the other end I doubt you could accurately measure the lake level to 1/2 of an inch.

Hey science guys...

could this be the source of the vibrations? Not the water flowing down?

[link to www.catholic.org (secure)]

Today's modern Radial Gate designs have revealed a new and powerful force dynamic that was not well known years ago. Up to 60 ton Radial Gates have experienced a powerful "vibration" oscillation condition from critical flow levels in the gate openings. A standing wave of high and low pressure oscillation develops on the lower skin plates of the radial gate that transfers a complex set of distortions and movements to the massive steel gate structure. Indeed, experts are now attributing this powerful resonant oscillation vibration condition as a key component to the catastrophic failure of the Folsom Radial Tainter Gate in 1995 [11]. The power of this multi-mode form of oscillation in the massive trunnion gate structure would be dominant in forces applied to the Oroville Spillway Radial Gate design to these weakly coupled side seal assemblies.

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

719 acre feet when you are talking 3,150,000 acre feet is like a few drops in bucket.

A wind shift in a lake that size will move the measuring gauge up or down more than that amount of water added into the lake.

The surface area of Oroville Lake at the level it is now is somewhat over 16,000 acres. Adding 719 acre feet of wter to that amount of surface area raises the lake by .0449 of a foot, or about 1/2 inch. (719/16,000 = .0449 .... 12" x .0449 = .54 of an inch)

Even on a small farm pond with NO WIND pushing water from one end of the pond to the other end I doubt you could accurately measure the lake level to 1/2 of an inch.

Yeah but if I understood the calculations, this is per hour. So at 1/2" per hour, that is a rise of over a foot a day. And this is with normal conditions. Now factor in the coming rainfall and the increased snow melt that will accompany...it's not an insignificant number.

I know a bad angle when I see one. The gate that is below the orange tarp above, that gate is leaning to the left.

Nevermind....I stand corrected. This was a calculated number over a period greater than one hour...But I also noticed that this calculation is of water that is "missing" from apparent leaks. The concern being that this is a lot of water just leaking out of the lake.

What could they be doing with the gates?
 Quoting: Anonymous Coward 77410359


Are they using those as jacks of some sort to put pressure on a failing or cracking section?

They don't appear to have buckets attached to lift anyone.

Trying to open them.
 Quoting: CleverCreator


Maybe trying to prevent them from bursting open. I know it's not much force but on a bearing that is barely holding, every bit counts.

Just a theory though

CAN ANY ONE OF YOU REFUTE THESE NUMBERS?

Emergency spillway overtops at 901. If gates closed & inflows high, emerg could get to 908 or more. Dam itself would not overtop till 922.

That's what I was thinking, but those wouldn't support much pressure/weight.
 Quoting: Anonymous Coward 77650159


If the thing is on the edge of bursting, 50 lbs of pressure can help.

But if that is what they are doing, dear lord its bad!
