Approximate locations of faults crossing the California Aqueduct, Coastal Branch, North Bay Aqueduct, and South Bay Aqueduct. Note: Mile Post locations in 1965 documents do not agree with actual Aqueduct Mile Posts in San Joaquin Section due to 1965 offset at ~MP 174.8 and subsequent changes to Aqueduct alignment after MP 174.8.

For the California Aqueduct Fault Crossings, San Gabriel, North Bay, and South Castaic data sets: Data was digitized from scanned mylar map and georeferenced using landmarks and the Public Land Survey System (PLSS) grid/coordinates from the scanned map. Faults were digitized from the faults on the scanned map. No additional interpretation conducted.
2015-11-01
For the Features identified during construction: Data were plotted along the Aqueduct centerline by locating the referenced milepost in the report and plotting a point on the centerline. Fault crossing data was then added to the feature class. Fault details from the construction reports were input as notes. No additional interpretation conducted.
