Los Angeles County Public Works is pleased to announce that sediment removal at Devil’s Gate Reservoir was completed on August 10. By September 15, and September 30, the County will finish final construction work at Devil’s Gate Reservoir and Manning Pit, respectively. The County extends our thanks to the community for its input, support and patience since the project’s start in November 2018. We are pleased that we were able to complete the sediment removal in an expedient and timely manner without creating major disruptions.
The planned four-year effort to remove 1.7 million cubic yards of sediment from Devil’s Gate Reservoir was accelerated by efficient sediment removal and favorable weather conditions. The project restored the facility’s flood control capacity to protect communities downstream while establishing a new permanent maintenance area.
Los Angeles Public Works will continue work on the habitat restoration project, restoring native habitat on the surrounding 70 acres. Almost 60% of the native vegetation planted is being obtained from the Hahamongna Native Plant Nursery.
Los Angeles County Public Works expresses special appreciation to the local residents, the Community Advisory Committee, local stakeholders, neighbors and businesses in the communities of Altadena, La Cañada, Pasadena, Irwindale, and Sun Valley for their continued collaboration in our efforts.
