RE: Papers on Dam Failures Jeff:

Thanks so much for the information. Jake Philip, ETB/DRAIRES just attended a National Academy of Sciences meeting on this topic.

Papers on Dam Failures Joe and Tom, I also found the discussion on Thursday very useful. Attached are some papers on dam failures and failure rates that we've found. They might be of interest. I'll keep you informed of the Jocassee issue as much as I can.

Hi Jeff, I learned a lot from our discussion yesterday. When the Utah PRA study comes in, I'd be curious to see if they discuss the plausibility/probability of failure mode similar to that which occurred at the Taum Sauk pumped storage facility in the Ozarks back in 2005. There the dam failed due to overtopping when pumps failed to turn off due to faulty level sensors. It might not be relevant since I don't think Taum Sauk had a spillway.
