Lesson’s Learned District and technical team reacted well

Anticipate the unexpected Project challenges Performance may change Resources will be thin Plan for backup DSO

Dam safety training is critical It works – project personnel noted the distress

Page 28: Corps of Engineers BUILDING STRONG ® TABLE ROCK DAM SLIDE – CASE STUDY Dave Paul, P.E. Lead Civil Engineer U.S. Army Corps of Engineers Risk Management.

Lesson’s Learned Communication

Project Personnel to DSO DSO to Engineers/DSPM Engineers on Site to DSO/DSPM DSO/DSPM to MSC and HQ OPM/Lake Manager and PAO to Public and Media

Constantly educate the public Purpose and Value of Projects Consequences without Projects

Consult regional dam safety engineers
