Are we experiencing the "WATCH THE WATER" scenario that Q speaks of? Kansas, Oklahoma, Missouri, Arkansas, Texas,California plus how many more having major flooding situations/risks going on right now? See US map water levels. And WTF is going on in Oklahoma with the Keystone Dam and the Arkansas River?
As of 10 am, the Keystone dam is within 3.35 inches of overtopping. Overtopping is the number 1 causes of dam failure. Water elevation is at 759.65 ft and it will overtop at 757.00 ft. Inflow into the dam is 303815cfs and outflow is 275000cfs and expected to be reduced to 266858cfs at 1 pm. (See chart). This appears to me to be a recipe for overflooding as more is coming in than going out.
To make matters worse, there is both a News on 6 and a Tulsa World article from 2011 with headlines: "Corps Says Keystone Very High Risk Dam".
"According to a news release from the Corps office in Tulsa, the reason is the potential consequences from
seepage through the foundation and the abutments of the dam
and
potential overtopping of the dam
during a probable maximum flood."
Both stories have a link to the USACE report. However, the link goes to a 404 Error File or Page not found which I find suspicious.

As far as I can tell, since these 2011 stories, the seepage through the foundation and abutments has not been addressed or repaired. I found a USACE News Release from 2015 where they are "studying" the situation: "The Tulsa District, U.S. Army Corps of Engineers will close traffic to the State Highway 151 bridge over Keystone Dam August 22 to September 1 to study the rock abutments and materials used to construct the dam. Keystone Dam was constructed between 1957 to 1964."
https://www.swt.usace.army.mil/Media/News-Releases/Article/916162/temporary-closure-of-state-highway-151-over-keystone-dam/ I can find nothing mentioning the actual repair of it. Furthermore, the bridge over the dam has never been closed for dam repairs.
All of the dams along the Arkansas River - from Kansas, Oklahoma, Arkansas are over flood levels. Missouri Rivers are over flood levels. We had rain this morning and a lot more is expected starting tomorrow and into next week.
I found this from 2009: https://www.ussdams.org/wp-content/uploads/2016/05/Abstracts_2009.pdf
SEEPAGE CONCERNS AT KEYSTONE DAM, OKLAHOMA

ABSTRACT
Keystone Dam is located on the Arkansas River just upstream of Tulsa, OK. Failure of
this dam would lead to catastrophic loss of life and significant economic loss in the Tulsa,
OK area.
Through on-going inspections, new seepage has been observed during flood pool
operations in each abutment of Keystone Dam. In addition, a recent assessment of
foundation materials and construction documentation for Keystone Dam indicate that a
filter was not installed in a cutoff trench in the foundation during construction of the dam.
A Screening Portfolio Risk Assessment (SPRA) conducted in 2006 identified seepage
through the abutments in the sandstone and limestone bedrock, and potential piping of
embankment material as a deficiency.
Recent investigations have included a geophysical survey to further identify seepage
locations, installation of piezometers in the left abutment, and the use of sonic drilling
through the embankment core and foundation to investigate the areas of concern. In
addition, an external panel of experts were engaged to review and assist in planning
further investigations and studies.
None of this is being mentioned at all to the public in our current extremely dangerous flooding situation to even give people an opportunity to make their own decisions as to whether to get the hell out of the way until this situation resolves.
