And then there's Oroville dam, about 25 miles upriver from me.
The dam is 900' feet tall. Oroville is the tallest dam made out of piled-up-dirt and stuff (it's
not a concrete dam, folks) in the United States. Current water level in the dam - 894.19 feet. And rising. . . (this data posted as of about 6:33 p.m. 05/28/19):
http://cdec.water.ca.gov/dynamicapp/QueryF?s=OROLet's see. I'm not a math whiz, but let's run some numbers here, just for fun: 900 minus 894.19 = 5.81 feet between the current water level and the top of the dam.
Current water releases (water being released from the lake): 6,902 cfs (cubic feet per second).
Current inflows (water coming in to the lake): 8,950 cfs (cubic feet per second)
Current amount of water in lake: 3,446,596 acre feet (yes, that's
millions of acre-feet)
Maximum amount of water the lake can theoretically hold: 3,537,577 acre feet
The floodgates remain closed. Current (limited) water releases are via the electricity generating station at the dam - water comes through a
really big pipe that comes through the bottom of the dam to turn the electrical turbines at the foot of the dam.
Is the dam safe with this much water in it? California Department of Water Resources assures everyone that, yes, it is absolutely, perfectly, 100% big-time safe.
Oh, yes. Almost forgot. It was the California Department of Water Resources that assured everyone that the emergency spillway was absolutely, perfectly, 100%, big-time safe. That is, until they gave 200,000 +/- people in the immediate area of the dam the message that the spillway could fail within the next hour, so "this is not a drill" get outta Dodge. Everyone - including me - grabbed their shorts and headed out the door.
Do I think I'm safe? Do I personally feel comfortable with the current messaging from DWR? Of course, absolutely, perfectly, 100%, big-time.
Which is exactly why I have a "get outta town" bag packed and ready, currently sitting at my front door. Also, my fingernails are getting kinda short. Maybe I should just quit chewing on them. . .
