are they opening dams downstream? they really could truck in a bunch of 4 foot tile to siphon over the banks and direct the flow past the work areas, close the dam gates and initiate the repairs. I dont think I would want to be working the boats placing the tile topside though On Mon, Feb 13, 2017 at 1:20 PM, Robert Andrews <i...@avantwireless.com <mailto:i...@avantwireless.com>> wrote: Putting plates into a waterflow of that volume will pretty much be certain to rip out of the concrete or create erosion of the concrete around the attachment points. Cavitation is a bitch... Right now they can't stop the flow. Also pretty much most of the spillway below the hole is gone, so there isn't a lot to attach it to. The turbines are shut down right now because the erosion has created a dam in the stream that has raised the water levels upstream to the point they cannot operate the turbines. The turbines were maxed out at 15K cfs up to that point. Yeah, I have been pretty much obsessing over this... My inlaws were stuck going nowhere in Yuba city last night for 4 hours in gridlock ( at one point not moving for 2 hours. ) before deciding it was safer at the house on the second floor...

At least until they take some inches off the reservoir. I wonder if there is a way they can set the angle on the turbines to waste more water there too. -----Original Message----- From: Robert Andrews Sent: Monday, February 13, 2017 11:28 AM To: af@afmug.com <mailto:af@afmug.com> Subject: Re: [AFMUG] OT - Oroville dam As of this morning they are saying the regular spillway is supporting the 100K cfs without further damage. If that it true, then there is the ability to deal with what's happening over the next couple of weeks, which looks like 4-5 sequential storms. We got a 4-5 day break in weather this week but if it goes back to last months pattern we are in serious trouble throughout the west. That spillway needs to do 100K cfs for weeks to keep pressure off the hillside below the emergency spillway. Californa and the Feds were sued over in 2005 to put concrete down on that hillside by the Sierra Club. The worse case situation is that the lake goes over the emergency spillway, it erodes below, the spillway fails and the hill below what was the spillway just keeps going away. Moving water, and it would be a lot, would grand canyon the hill... It would be enough water to destroy most of the feather river and Sacramento levee system below the dam.. That would be really really bad... ( Inlaws in Yuba city )... On 02/13/2017 08:47 AM, Jason Wilson wrote: 100,000cfs is correct. That spillway will support 250,000cfs, but the Feather River channel will only support about 216,000cfs. It has been 10 years since the Channel has been stressed to this point, last time there were levee breaches. Their hope is to drawdown the reservoir 50 feet below the rim to do a couple things, one is to take pressure off of the presumed damaged emergency spillway. The other is to make room for precip that is coming into california towards the end of the week. Of course they cannot do any repairs to the facility until after the rainy season is over, and the snowmelt had finished.
