Arkansas, Oklahoma Prepare for 'Worst Flood in Our History' with More Rain Forecast

"Engineers are trying to prevent the even more catastrophic flooding that could come if Keystone Lake overflows its floodgates, the Tulsa World reports."

Keystone Dam was overtopped at midnight last night. It is now overtopping by almost 2". Keystone dam is at PMF (probable maximum flood).

"Overtopping is a common failure mode for earthen embankment dams. Currently, numerous dams cannot pass the Probable Maximum Flood (PMF) without overtopping. Many of these embankment dams would have a high probability of failure if subjected to a sustained overtopping of a foot or more." (http://watershedgeo.com/civil/dam-overtopping/)

TULSA, Oklahoma – The U.S. Army Corps of Engineers says the Keystone Dam in Tulsa County is considered a 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."

Keystone Lake is a huge lake. Keystone Lake is about 23,600 acres in area and 73 feet deep. A breach would not only be catastrophic for Tulsa but for everyone living along the River downstream. This is an extremely serious situation.

Who would benefit if Little Rock,Arkansas got wiped off the map? Watch the water.
