The Sonoma Valley Knowledge Base

The Sonoma Valley Knowledge Base is a library of local and regional information needed for science-based watershed management. Planners, scientists, and the public can find information here on many topics — groundwater, stream flow, historic changes to the stream and watershed system, fish habitat quality, and many more aspects of keeping a watershed healthy.

The Knowledge Base specifically supports the creation and review of a new Watershed Plan for Sonoma Creek, updating the 1997 Sonoma Creek Watershed Enhancement Plan by sharing information resources and the documentation that makes them usable. Monitoring and mapping data, reports, images, and other resources can be discovered and downloaded in this online digital library.
