Starting as soon as Monday, December 7, 2020 the Contra Costa Loop Canal will be shut down for approximately four months while we conduct the annual cleaning. The work will begin at the Naval Weapons Station and proceed along the Loop Canal through Clyde, Concord, Walnut Creek, Pleasant Hill, and Martinez. See the map below.
At times, sections of the Contra Costa Canal Trail will also be closed to ensure public safety while heavy equipment is in use. Signs will be posted along the trail ahead of any closures. We expect the Loop Canal to be back in service by early April 2021.
Each winter, the District conducts a full cleaning of 21 miles of the Contra Costa Loop Canal from Clyde to the Martinez Reservoir. The annual cleaning is performed during the winter months when water usage is low and customer impacts can be minimized. The cleaning is safely managed by District crews by utilizing equipment to push the accumulated sediment from the sides and bottom of the Canal. The sediment is then removed with a crane for final disposal.
