Groundwater Users Information Data Exchange (GUIDE)
Groundwater in Petaluma Valley is an important shared resource. State law requires that communities protect their groundwater to make sure it’s clean and available for you and other users, today and in the future.
The Petaluma Valley Groundwater Sustainability Agency (GSA) was formed in 2017 to comply with state law and to manage groundwater resources as described in the Petaluma Valley Groundwater Sustainability Plan (GSP).
The Groundwater Users Information Data Exchange or GUIDE program was developed to provide the GSA better information about groundwater use in the valley and to give you and other groundwater users an opportunity to view the available data about your parcel’s assumed groundwater use.
Through the GUIDE program, you can view, correct, or confirm the data the GSA has assumed for your property by reviewing the steps below and completing the GUIDE survey or by calling the GUIDE information line at (707) 243-8555.
