For those following the Oroville spillway situation, there are new posts on the big thread that may be of interest. (links below)

DWR's 1960's Split spillway "engineering political solution" coming back to haunt the future? (new Failure mode of the entire dam)

Unexpected waterflow observed in places in upper spillway - Why?

Expert Board of Consultants swizzled flow number specifications for the New Main Spillway and the New Emergency Spillway. Why?

A "flip bucket" temporary fix proposal to "jump" spillway flow over the damaged section "plunge pool"

Thanks for the excellent way for us non engineers, non rock people as Seldon calls geologists and non physic majors to decide what to look at and keep up to date on this boon doggle.

March 27 - they are see-sawing between full spillway / closed power plant, and full on power plant / closed spillway to try to maintain levels and avoid scouring

New information on an unusual situation: A well known long term "leakage" or "wet area" on the backside of the big main dam. Dam Inspectors have noted this in 2014 and 2015 reports and have recommended "investigations" and "actions" to be taken. So far, no evidence this has been investigated. See more at post links to the big thread below.

2014/2015 Dam Inspection Reports: "Long Standing..Wet Area" - midslope dam backside seepage (being ignored?)

More Info: Mid-slope Main Dam Erosion channels from unaddressed "Weepage" inside of dam
