OROVILLE, Calif. (KCRA)
Crews are beginning to make repairs to the spillways at Lake Oroville, the California Department of Water Resources said.
Efforts are underway to make repairs to both the primary and auxiliary spillways at Lake Oroville, officials tweeted.
Military-grade helicopters are picking up 1-ton containers of rocks from a parking lot near Lake Oroville, flying them to the erosion scar at the emergency spillway and dropping the containers into the hole.

Wouldn’t filling the hole with large, heavy boulders just provide more ammunition that will be sent downhill when the thing comes apart?
The 'oh so vile ones' in the MSM are impressed with large noisy helicopters... "If it bleeds it leads..."
“Additionally, the report states that although the employees were instructed to open the valves at a 100 percent water flow rate of 5,400 cubic feet per second, river valves have “historically failed when operated at 100 percent” and “employees expressed safety concerns with operation of the river valves to 100 percent.””
From 2009 incident. Hope the river valves hold up...http://www.chicoer.com/article/zz/20100223/NEWS/100227917
That emergency spillway/weir erosion, combined with the water flowing backwards (from the ground into spillway) through the vents on the sides of the main spillway’s sluice, means there’s serious water in that soil. And, what’s happening right now above and below the main spillway sluice’s failure edge?
But but but, they’re using “military grade” helicopters!
Since that phrasing was used, I’m sure everything will be Alright.
A while back I read Paul Johnson’s “The Johnstown Flood,” which describes the 1889 flood caused by the failure of an earthen dam after many days of heavy rain. Like the Oroville Dam, it had shown signs of erosion and cracks for several months, but the engineer who urged that it be repaired was ignored. The water roared down a narrow gorge for 15 miles and and wiped out several towns along the way. It reached Johnstown in the late afternoon, and people who saw it coming said they couldn’t see any water. All they could see was a 23’-high rolling wall of trees, railroad cars, buildings, dead animals, and other debris. I’ll never forget that description.
Up to eight inches of rain between now and Monday for the mountains around Oroville.
Drop the illegals in there, that’ll plug it up fast
And save $$$ overall in the process
Wow. The water is always The Boss.
In the experimental dam fail video I posted, one of the engineers can be heard saying, “Something different happens every time...the previous dam failed on this side of it.” When you take that into consideration, the unpredictability factor is most frightening.
What must be remembered about the terrible situation of the Johnstown flood compared to the Oroville Dam is that the Oroville Dam is literally an order of magnitude (10x) larger than the South Fork dam above Johnstown.
Possible concern: Large Bubbles in water in front of Emergency Spillway - may indicate water flowing under/through the Emergency Spillway.
Sorry for any large image inconvenience. However these rising air bubbles are huge. I’ve circled the large bubbles breaking the surface in the image. These significant bubbles may indicate water is flowing under/through the Emergency spillway foundation. See the youtube at the 40 second mark as the helicopter camera/pilot zoomed in on these. It caught their eye for them to zoom in on it.

Fox10 Oroville dame update Feb 13, 2017
Thanks again for sharing your knowledge and expertise.
That station seems to be doing a better job than our N. Cali stations are.

Why hasn’t [Dem gov.] fixed the dam? Brown has been in office since 2011. Republican Schwartzenagger was in from late 2003 to late 2011. According to the article below, the issue of earth and rock fill rather than a concrete cover for the emergency spillway was raised in Oct. 2005 by those pesky environmentalists Sierra Club and others. They went to the Federal Energy Regulatory Commission with the issue who then went back to the state Department of Water Resources who conferred with the local water agencies who said they were unnecessary (since they would be the ones paying most of the bill). So the buck was passed in 2005, by those who will now probably have to pay much bigger bills unless the Trump government decides to help out, which may not be likely.
I read the book several decades ago, but if I remember correctly, the glitterati who owned shore front real estate were very much against the idea of drawing down the water level for safety because it would have made for an ugly shore line.
Per LA times:
— The FAA has issued a temporary ban on flights around the Oroville Dam. Stated reason: to allow emergency aircraft to operate safely.
This ban goes to May 17. Yet today there is no helicopters operating.
The ban includes drones.
I understand a flight safety concern, but this cuts off a valuable source of news video images. If it weren’t for the Fox 10 copter video the “bubbles” in the water near the emergency spillway would not have been captured (& be public).
I guess we’ll have to “trust” our government to keep us accurately appraised..
Talk about poor planning. Maybe if it was up on one of the river banks.
