Dam, Reservoir Owners, Operators Should Begin Lowering Water Levels

Columbia, SC (WLTX) If you own or operate a dam the DHEC is asking that you begin to lower water levels, especially if you live in an area that could be impacted by Hurricane Matthew.  

Hurricane force winds can topple trees causing large voids where trees are uprooted. Loss of soil from a dam can impact its structural integrity and can provide a path for water from the pond to exit in an uncontrolled manner. This condition may lead to failure of the dam.

 "Owners of reservoirs with functional gates or flashboards should considering operating them to provide additional storage for the anticipated rainfall," said Jill Stewart with DHEC’s dam safety program. "If there is a dam downstream of your dam and you are lowering your water level, please call the owner of that dam and advise him or her about what you are doing. Before and after the storm has passed, any accumulated trash and debris should be cleared from spillways."


DHEC has implemented the CodeRED system to automatically notify dam owners via voice call, text messages and email to take steps in preparation for the potential significant rainfall. 


"Dam owners should be aware of the conditions at their dams during such events," Stewart said. "If problems develop and failure of the dam might be imminent, the owner or operator of the dam should contact local public safety officials and downstream property owners.
