November 2020 Lunch Presentation

A Tale of Three Dams

ASCE Geo-Institute Seattle Section & AEG Joint Meeting
Thursday, November 19, 2020 at 12:00 PM – 1:00 PM

Three dams (Tinemaha, North Haiwee, and South Haiwee) in the Owens Valley are located on or adjacent to active faults, including the Owens Valley fault zone that produced a large surface-rupturing earthquake in 1872 (about 40 years prior to the construction of these facilities). These aging dams are being reassessed and replaced or rehabilitated by the Los Angeles Department of Water and Power to improve their resilience to the hazards of ground shaking, liquefaction, and fault displacement. This presentation will provide a brief overview of the aqueduct system and summarize the fault investigations performed for these three dams.
