The Butte, Colusa, Tehama, and Vina Groundwater Sustainability plans make it clear that groundwater exploitation is planned and accepted in the counties of Butte, Colusa, Glenn, and Tehama. The Plans accept the dewatering of up to 20 percent of domestic wells and groundwater collapse of over 80 feet before any action must be taken to protect the groundwater basins for all users and ecosystems. Domestic well damage and sinkholes became prominent in Glenn County in 2021, indicating that serious abuse of the groundwater under existing oversight has already harmed the people and environment of the region. Additional degradation with implementation of the Plans most stop!

This significantly large area in the Sacramento Valley has been the target for this form of abuse for decades, but it is being formalized in the Plans without the benefit of any environmental review and analysis. Consequently, AquAlliance has filed three lawsuits to stop implementation of the Butte, Colusa, and Vina subbasins’ plans.
