I have made multiple posts about the condition of California’s Oroville Dam and the threat it poses to people living downstream. The basics are this dam, due to massive amounts of rain overtopped at 901 feet, caused a near disaster when the “emergency release channel” nearly collapsed and nearly sent a massive wave of water roaring downstream. “The powers that be,” managed, barely managed, to prevent an historic dam collapse disaster. They then spent nearly one billion dollars doing the kind of basic dam maintenance they had not done for DECADES. The result was no disaster and people went back to their lives, assuming any future danger had been dealt with. This assumption is wrong, if the following link to an article is correct. The link is below.
Collapse of Oroville Dam Has Become a Distinct Possibility
The Oroville Dam is in crisis. In the past several weeks, I have spoken to Paul Preston multiple times about the continuing crisis. This morning, April 18, 2019, Preston is in court attempting to file an injunction against the Department of Water Resources.of California. Consequently, Preston is not able to speak with me on this topic. However, I do have access to other sources and I have obtained direct evidence which strongly indicates that the Oroville Dam is in imminent danger. Here is what we know as the early morning hours on April 18, 2019.
Within the Past Six Days the Dam Has Begun Periodic Over-topping
The Oroville Dam is the biggest earthen dam in the United States, standing at a height of 901 feet. The dam is experiencing threats to its existence from a number of sources. Here was a recent story which indicated that over-topping was a looming threat. This alone, could collapse the dam.
From Agenda 21 Radio:
Many New Californians in the Butte, Sutter and Yuba counties have expressed great concern over what they have been seeing error codes from the Oroville dam data exchange center’s hourly charts from the Department of Water Resources. The error codes (N) started showing up on the charts April 12, 2019 at 3:00 pm PST. when the last reported elevation of the water in the reservoir was at 860.83 feet. By 4:00 pm PST the elevation was reported at 533.22 a drop of 327 feet in the water level. Noted alongside the measurement is letter (N) which indicates there is an error in the reporting.
Of big concern for people was after 44 hours without a proper reading from the Oroville Dam what was the real level of the reservoir since the last reading that was produced without an error code (N) was Friday April 12, 2019 at 3:00 pm PST that report showed an elv. at 860.83 ft
As of Sunday at 12:00 pm pst 44 hours after the error code showed there was only minimal data that could be used such as the inches per hour which was not reliable but the Inflows were 19,559 vs Out flows of 8,002 at 12:00 pm PST April 14, 2019 with the main spillway is NOT in use.
“We don’t know the levels. What are the exact numbers?” stated one Butte County resident.
The dam max reservoir is 899.9. Over topping starts at 901 many people were thinking there was an over topping threat as they saw on February 11, 2017. The February 11, 2017 incident was the led to the February 12 dam failure that forced the Sheriff to call for an emergency evacuation of 190,000 people from the inundation zone.
From Bad to Worse
Noted dam expert, Scott Cahill’s material on the Oroville Dam’s condition was forwarded to me. Here is what I have at this point in time..
On the right side of the spillway the plates are leaking. There should be NO water leaking from the seams.
The leaks are obvious in all IMG pictures. Spillway is suppose to be smooth. Evidence in all IMG pictures. Notable plate buckling in IMG 8027b, IMG 8026B, IMG 8025b and IMG 8034 From Dam specialist Scott Cahill Watershed Services. I am being sent these photos later today. I am not sure about the delay in doing so and they will be published as soon as they are received. I suspect that the early is due to the fact that that photos are going to be used in court this morning in order to gain an injunctions against the Department of Water Resources who are using dynamite in the vicinity of the dam in order clear debris. The fear among local experts is that the dynamite could trigger a catastrophic collapse of the dam. This constitutes the main legal argument against DWS in court as per the filed documents.
Eyewitnesses have told me that the spillway is collapsing. There is buckling in the middle of the dam. It is estimated that if the top of the dam fails, the dam will lose about 30-40% of its height. This would lead to massive over-topping of the 600 feet that would be left and eventually it is expected that the dam would collapse.
ADDENDUM TO THE ARTICLE 9AM Pacific April 18, 2019
These pictures originated with Scott Cahill. These photos show clear cracks and damage to the spillway, mentioned earlier in the article. Once can see the bulges forming as well. This dam is a critical state.
