News Release


Pasadena Now


The state has granted the Los Angeles County Flood Control District $28 million for the construction of a five-mile pipeline that will connect Devil’s Gate Dam in northwest Pasadena and Eaton Canyon Wash in east Pasadena.

Under the plan, stress on Devil’s Fate Dam will be reduced as water is transferred to Eaton Canyon Wash, where “spreading grounds” will be constructed to allow the water to soak into the ground and add to to the water basin.

The grant was awarded under the Disaster Preparedness and Flood Prevention Bond Act of 2006. The construction is expected to begin in 2016, Principal Engineer Keith Lilley told the Pasadena Star-News.

Meanwhile, the Los Angeles County Flood Control District is planning to remove an estimated 5,000 cubic yards of accumulated sediment near the face of Devil’s Gate Dam to reduce the flood risk to the communities downstream of the reservoir adjacent to the Arroyo Seco.

Two public meetings will be held on the dam sediment removal project: on Wednesday, November 6 from 6:00 p.m. to 8:00 p.m. at the Rose Bowl Stadium, 1001 Rose Bowl Drive and on Saturday, November 16 from 2:00 to 4:00 p.m. at Community Center, 4469 Chevy Chase Drive, La Cañada Flintridge.

The 2013 Interim Measures was expected to start last September 16 and be completed within a month. The draft of the Environmental Impact Report will be presented to the public as a part of the 60-day comment period and public hearings. A final report will be prepared after the meetings, which will be followed by a certification process and a notice of determination.
