California's Central Valley

Central Valley Hydrologic Model: Digital Datasets

The USGS and the Bureau of Reclamation are working together to provide models, tools, and supporting datasets for the Central Valley Hydrologic Model (CVHM).

Available Datasets

There are two databases available:

Central Valley Spatial Database

Original, unformatted source datasets

Central Valley Hydrologic Model (CVHM) Database

Processed datasets manipulated and resampled to the one square mile grid for the CVHM

Dataset Workshop

In January 2012, the United States Geological Survey (USGS) and the Bureau of Reclamation conducted a workshop that discussed the Central Valley Hydrologic Model (CVVHM) and related datasets, and how these tools help water managers to understand water use and movement, predict water-supply scenarios, and address issues related to water competition to help manage sustainable water resources.

Workshop Presentations

The presentations from the workshop are now available for download (in PDF format):
