Projects and Management Actions (PMA) – Submit your ideas
We want to hear from YOU! We are looking for ideas about potential projects and management actions (PMAs) that could be evaluated and possibly included in the Colusa Subbasin Groundwater Sustainability Plan. We have launched an online form to collect your ideas. Project Submittals are due May 3, 2021 by end of day. The form is available in three formats. Click the link below that works for you:
- PMA Form, Word document

Coordination with other GSAs and GSPs
In the Northern Sacramento Valley (NSV), inter-basin coordination is critical as Groundwater Sustainability Agencies (GSA) develop their Groundwater Sustainability Plans (GSP). Since groundwater subbasins in the NSV are hydrologically interconnected, water management decisions and actions in one subbasin could change aquifer conditions and affect flows to other subbasins. Understanding and accounting for these processes is key to achieving and maintaining sustainability.
GSAs in the NSV region are actively coordinating GSP efforts. An inter-basin coordination webpage has been set up which includes key information and access to relevant meeting materials (agendas, meeting summaries, etc.). You can access the webpage here: Interbasin Coordination Website
