A new large bulkhead was installed on the Red Rock Dam this winter. Assistant Operations Manager John Holt says that the installation went well, and ahead of schedule. But the bulkhead won’t be tested until it is commissioned by the contractor who handled the installation. The bulkhead will be able to isolate individual gates for maintenance projects without the need to do a draw down on lake levels. Holt says the only difference that people using the lake for recreation will notice is that lake levels will stay the same during maintenance work.
