Land Subsidence

The California Department of Water Resources (DWR) has drafted Best Management Practices (BMPs) for monitoring land subsidence. This USGS site includes information, tools, and data relevant to DWR's BMPs, and additional resources, to help water managers address key components of the required Groundwater Sustainability Plans (GSPs), including monitoring.

The USGS California Water Science Center monitors the cause, extent and potential effects of land subsidence in California. Visit our dedicated Land Subsidence page for more information: USGS Monitoring, Modeling, and Analysis of Land Subsidence in California.

The USGS California Water Science Center works with Local, State and other Federal agencies to conduct studies that will help give water managers the knowledge they need to effectively allocate water resources under increasing demands.
