Groundwater Studies

The Shasta Valley RCD has been working on studies of groundwater in the Shasta River watershed for 10 years.  Two studies have been completed in collaboration with the California Department of Water Resources (DWR).  These studies were designed to collect and review existing knowledge, areas of interest and information gaps.

Shasta Valley Groundwater
This is an introductory foundation to understanding the highly complex Shasta Valley groundwater system.  It describes the geologic and precipitation history that created that created the groundwater system with its 8 sub-areas, and reveals patterns and trends in groundwater use for agriculture and domestic use.  Future concerns are highlighted, from what is known such as increasing population and development, to the unknown, including climate change.  In the future, we intend to prepare more detailed presentations focused on specific details of Shasta Valley Groundwater system.
