LOS ANGELES DEPARTMENT OF WATER AND POWER OWENS LAKE DUST MITIGATION PHASES 7A, 9, AND 10

Owens Lake is a mostly dry lake bed located within Owens Valley. Owens Lake held a considerable amount of water until 1913, when water sources were diverted to the Los Angeles Aqueduct, causing it to gradually desiccate. Today, the Owens lakebed produces windblown dust that exceeds federal air pollution standards for particulate matter, which is harmful when inhaled and can lead to a variety of health problems. To address this issue, the Los Angeles Department of Water and Power (LADWP) is implementing control measures to curtail dust plums on 6.1 square miles of lake playa with this dust mitigation project. CWE provided civil design services for dust control measures, including irrigation, vegetation, gravel placement, and soil tillage.
