The Groundwater Sustainability Plan (GSP) is a detailed strategy designed to ensure that the groundwater in the Wyandotte Creek Subbasin is managed responsibly for long-term sustainability. It is a requirement of California’s Sustainable Groundwater Management Act (SGMA), which empowers local agencies like the Wyandotte Creek Groundwater Sustainability Agency (GSA) to take control of groundwater management and protect this essential resource.

How Was the GSP Developed?

The Wyandotte Creek GSP was developed through an inclusive and collaborative process that brought together local stakeholders, groundwater users, public agencies, and members of the community. Public meetings, technical studies, and stakeholder input shaped the plan to ensure that it addresses the unique water challenges of our region. This community-driven approach ensures that the GSP reflects local priorities and needs while meeting state regulations.

What Does the GSP Aim to Achieve?

The GSP is designed to protect and balance the needs of groundwater users—farmers, rural communities, and the environment—while ensuring the long-term health of the aquifer. It outlines:

• Groundwater Monitoring: Regular monitoring of water levels, quality, and usage.
• Sustainability Goals and Thresholds: Clear targets for water levels, quality, and other metrics to prevent overuse, contamination, and other undesirable impacts.
• Projects and Management Actions: A variety of local projects and practices aimed at improving water use efficiency, increasing groundwater recharge, and preventing depletion.
• Adaptive Management: Flexibility to adjust strategies based on changing conditions such as droughts, population growth, or climate change.

Why Is the GSP Important?

The primary goal of the GSP is to ensure that groundwater is managed in a sustainable way, providing a reliable water supply for local communities, agriculture, and environmental needs—both now and in the future. The plan is essential to:

• Safeguard Water Supplies: Ensure there is enough water for everyone, especially in rural areas.
• Support Agriculture: Maintain the agricultural economy by securing access to water for farming.
• Protect the Environment: Preserve groundwater-dependent ecosystems and protect water quality.

GSP Review and Updates: A Living Plan

The GSP is not a static document. It must be reviewed and updated every five years to account for new data, emerging challenges, and ongoing public input. This adaptive approach ensures that groundwater management continues to meet the changing needs of the community and remains aligned with state regulations.
