U.S. awards headgate rehab contract for Dry Falls Dam in Washington

The U.S. Bureau of Reclamation has awarded Washington-based Knight Construction & Supply Inc. a $1.39 million contract for rehabilitation and replacement of headgates at Dry Falls Dam in Washington.

Dry Falls Dam and North Dam impound Banks Lake in Grand Coulee, which feeds Columbia River water into the main canal of the 6,809-MW Grand Coulee hydropower project.

Reclamation seeks installation of six new government-furnished bulkhead gates with underwater inspection required. The contractor also is to remove bulkhead gates after completion of gate rehabilitation work and clean, prepare and coat six radial gates. Related peripheral work is required.
