This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life.

Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 09/21/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
