Devil’s Gate Reservoir Restoration Work to Resume

LA County Public Works will resume sediment removal at Devil’s Gate Reservoir as early as May 3 and continue these operations through November.

LA County Public Works, in coordination with the contractor Griffith Company, began preparations on April 19 to resume sediment excavation and removal inside the reservoir and are farther along in excavation and removal quantity from the reservoir than originally predicted. Therefore, the project may very likely be completed by the end of November 2021.

To date, the project team successfully removed more than 980,000 cubic yards of sediment. Meanwhile, habitat restoration activities continue in the project natural areas. To protect hikers, cyclist and workers during construction, a number of trails within the reservoir, including the tunnel to the Lower Arroyo Seco Trail, will be closed during project work hours, Monday through Friday, from 7 a.m. – 3:30 p.m. The Rose Bowl Loop and recreational trails within Hahamongna Park and along the north side of the reservoir will remain open to visitors. Please refer to the trail closure map for details.
