Sediment Management

Devils Gate Dam
Since 2011, the Los Angeles Flood Control District (LACFCD) has implemented interim measures at Devil's Gate Dam and Reservoir which consisted removing sediment from the area immediately in front of the dam and placing it in Johnson Field.
This fall, LACFCD is once again planning to remove accumulated sediment near the face of Devil's Gate Dam. Due to the extremely dry storm season this past year, the anticipated amount of sediment to be removed is less than 5,000 cubic yards. As with previous years, sediment will be stockpiled at Johnson Field to be removed when the larger Devil's Gate Sediment Removal and Management Project takes place. Additionally, any green waste such as tree branches and other vegetative matter that is removed will be trucked to the Scholl Canyon Landfill in Glendale at a rate of no more than 10 trucks per day to avoid traffic impacts to the surrounding neighborhood. Attached is an informational flyer that will also be posted at the Dam near the surrounding trails. Work on this year’s interim measures is expected to start September 15, 2014 and be completed in approximately two months.
LACFCD is also working with our consultant, Chambers Group Inc., to finalize the Environmental Impact Report (FEIR) for the future Devil's Gate Reservoir Sediment Removal and Management Project. The FEIR is expected to be released by the end of this year. Prior to taking the FEIR to the County of Los Angeles Board of Supervisors for certification, three community presentations will be held to present the findings and results of the FEIR. When the dates and locations of the public meetings are finalized a "Save the Date" notice will be sent out to interested stakeholders on our project mailing list and posted on this website.
