The Paso Robles Area Groundwater Authority (PRAGA) was formed in 2025 to help ensure a sustainable future for the Paso Robles Subbasin—our region’s primary source of groundwater. This vital resource supports agriculture, businesses, and homes across the area, but it is under increasing pressure from overuse and drought.

To meet the requirements of California’s Sustainable Groundwater Management Act (SGMA), PRAGA is responsible for implementing a Groundwater Sustainability Plan (GSP). This plan outlines how we will monitor, manage, and protect groundwater supplies over the long term.

Groundwater Sustainability Agencies (GSAs) in the subbasin had previously been coordinating basin-wide activities through a memorandum of agreement (MOA), but the GSAs expressed a desire to coordinate under a single joint powers authority to implement the GSP efficiently including a way to fund basin-wide activities, and formed PRAGA to do so.

The following GSAs are involved in PRAGA:

• County of San Luis Obispo GSA
• City of Paso Robles GSA
• Estrella-El Pomar-Creston Water District
• Shandon-San Juan Water District
