Lake Don Pedro...

Mosul Dam. The standard outlet is plugged with debris, and the spillway gate is hopelessly jammed. Last I heard it had about a year to expected failure; that news was about a year ago. There’s a million or so people downstream with no hope of evacuation when it breaches. Worth looking up.

Seven, seven, seven, seven...

We must have gotten several inches in a couple of hours today it was nuts - still raining its been raining since 5:30 this morning - torrential deluge for about six hours.

We sure got doused here in the South Bay / Peninsula area the last 12 hours. It was coming down nonstop for hours. Normally we get short squeals blowing through, not the steady drenching.

Last 24 hours (to 9:00 PM PST 2/17/17). Crimson is 3"; dark blue/indigo in LA is 5". Scale keeps getting chopped off.

The lake is beyond full! What’s funny is I was reading this thread while you pinged me.

Flood Control Dam #3 (FCD#3) was constructed in year 783 of the Great Underground Empire to harness the destructive power of the Frigid River. This work was supported by a grant of 37 million zorkmids from the Central Bureaucracy and your omnipotent local tyrant Lord Dimwit Flathead the Excessive. This impressive structure is composed of 3.7 cubic feet of concrete, is 256 feet tall at the center, and 193 feet wide at the top. The reservoir created behind the dam has a volume of 37 billion cubic feet, an area of 12 million square feet, and a shore line of 36 thousand feet.

The construction of FCD#3 took 112 days from ground breaking to the dedication. It required a work force of 384 slaves, 34 slave drivers, 12 engineers, 2 turtle doves, and a partridge in a pear tree. The work was managed by a command team composed of 2345 bureaucrats, 2347 secretaries (at least two of whom can type), 12,256 paper shufflers, 52,469 rubber stampers, 245,193 red tape processors, and nearly one million dead trees.

Someone out there will know where this came from.. ;-)

Mosul dam was built on soft and porous rock. Hydraulic pressure forces water through the limestone? dissolving a bit over time. Have been treating the symptoms with grouting since it was built, until ISIS gained control of the area, and maintenance ceased.
