2008 Update on Sacramento Valley GPS Height-monitoring Project

The Yolo County Subsidence Network monitoring project was the template and inspiration for DWR to expand a monitoring project throughout the Sacramento Valley.  Jim Frame, Frame Surveying and DWR staff are coordinating the surveying activities. In Yolo County, the cities of Davis and Woodland, Yolo County Flood Control & WCD, and UC Davis have committed staff or equipment to the project in addition to paticipation by local agencies in at least six counties in Northern California.  Observations in Yolo County took place between May 2 to May 22, 2008.
