i12 Levee Breaks Historic
type: Dataset
description: Database of historical levee breaks in the California Central Valley, particularly in the Sacramento-San Joaquin Delta. Dataset was built over years based on a variety of sources and ongoing incidents during the period in which the dataset steward was in the Delta Levees Program. Consequently, it primarily consists of levee failures in the Delta, plus additional levee failures mapped by the State Office of Emergency Services for the 1983, 1986, 1995, and 1997 floods throughout the Central Valley. It is useful to know where historic breaks occurred for ongoing purposes requiring geotechnical and engineering information. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.1, dated September 11, 2019. DWR makes no warranties or guarantees —either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data. Comments, problems, improvements, updates, or suggestions should be forwarded to gis@water.ca.gov as available and appropriate.
