I used 900', so 1700' would explain the difference and get you to 12000 cfs neighborhood.
Interesting that Mannings (friction) is not a factor in the weir equation. I guess it just changes the shape of the water surface as it flows over the weir and does impact flow in a meaningful way. |

Seriously ProFryan, Thank you for your time, money and effort for keeping us abreast on the dam. I've been following along since the beginning and your hard work made this the best thread for natural disasters.

Yesterday afternoon one of the reports said around 12000 cfs at the level then. I've seen a few differing reports of the weir width which did you use for the calculations? 1730 ft seems to be the right number. View Quote View All Quotes View All Quotes Quoted:

At 902.5' I calculate the wier's flow at 5100 cfs, which probably makes sense when comparing the OPs pics of the muddy outflows. To cope with flows we saw Friday, the reservoir would be around 911' (assuming 55k output of the normal spillway). That's a 10' wall of water.

With even more flooding and the wet season extending it, how do farmers even get into their fields? The lower lying areas in the Valley are not going to be worth much except for rice. Nobody is looking out 6 weeks/6 months in the media, it's all about the daily news cycle which is why it's been ignored up to now. The salmon fingerlings being rescued rated higher. The last time I checked the world radar and panned west into the Pacific it looked like rain for thousands of miles moving toward California - a Pineapple Express - and that is not going to facilitate getting crops in and worked in the early part of the growing season. Back here farmers aware of it would just write off even trying and wait until summer to go for one crop before winter. For big commercial farms it's already not looking good. For legal migrant pickers it's not looking good. I won't be surprised to see lettuce from Guatemala at double the price in stores. It's happened before with rain or frost. We have that problem right now, it's already too warm, but our pattern shows we can get 6-7" of snow and freezing temps late in the spring killing most of the fruit buds and damaging the early wheat. Farming is no bed of roses. We're concerned about a dam collapse but the potential long term impact of a wet spring and early summer means that ag will suffer considerably. During the '87 drought farmers switched up crops and tried pumping the acquifer but the frost in 90-91 was the major issue. It's always somethin'. View Quote My Aunt is in the agri-seed business and the wet weather has killed her season. Fields are too soggy to get into and no end in sight. Seed business is different than produce because, as I understand it, the plants take a bit longer to go to seed and the time needed for maturity is flying out the window. |

I'd be out there anyway, you guys bring more knowledge to the table which is nice. I'm kind of shocked actually at the lack of people out where i was. Once I got back to my truck and driving back, no joke I drove by hundreds and hundreds of people looking at maps trying to figure out how to get a good view. Hundreds. |

So with a name like Oroville, and the erosion taking place, a bit of prospecting might be profitable in a few months.
If that is still legal in Ca. |

Is the guy doing the live feed posted yesterday (pseudojd) the OP of this thread? If so, get back out there!

I read about a few things on here and two days later it makes the news. This is true. ARMCOM founders should take this a step further and actually develop this into a business plan and start a "NO FAKE NEWS" network using members as reporters. That would be helpful to the MAGA movement IMO. ProFryan could be the first reporter! Cheers & MAGA! Go ARF ![]() |

hmm... Lake levels peaked at 902.59 at 3am. It's down to 902.52 Now.
Outflow from the regular spillway has remained at 55k and inflows have dropped. Inflow is now at 52K... Found this pic probably taken yesterday... still looking for new pictures from today. ![]() http://www.parks.ca.gov/?page_id=29411 Remains the only live cam up I know about. |

View Quote Hopefully the chopper will go over again. Until then, those numbers could be made up since they've managed to shut down all non-state approved media, while getting the state-approved media's attention in a bunch of different places. I can't believe they shut off access to any vantage points. I understand closing the close areas for safety reasons, but closing down all of them to prevent looking seems... odd. |
