I thought this might happen....

Big storm overnight....  1.38" of rain fell in one hour starting about 2:30AM.  The storm tracked north right through one of the watersheds that feeds my pond.  Went out at daylight and saw the high water mark but no water way north of the dam.  Oops.  Looks like it slowly blew out each side of the dam and drained out.  Still have 8' of water in the pond but most of the dam is gone now.  Water was still running into the pond NW of the dam 12 hours after it stopped raining.  My contractor is coming out when the roads dry to assess the damage and to talk about a scaled down repair.  Think I will just have to settle on small pond instead of a lake.  Just wish there was light to get a photo of the full fill before the failure.  GoogleEarth image shows just how much water was backed up before the blowout based on what I saw this morning.  Since this was an experiment, I was mentally prepared for this eventuality so I'm not entirely surprised, only mildly disappointed and rather amazed at the power of nature.  Nothing ventured - nothing gained.  78,94,63, 1.38",B
