The community of San Miguel in California is facing conflicting claims about its water supply. While officials have claimed there is a water shortage in the Paso basin to secure grant funding, the San Luis Obispo County Planning Commission has approved a new 181-home development project that would rely on the same basin's groundwater. This raises questions about the true state of San Miguel's water resources and how they are being managed.

Why it matters

The discrepancy between San Miguel's claims of water shortage and its approval of new development that would increase water usage highlights potential issues with transparency, consistency, and accountability in the community's water management policies. It also raises concerns about the sustainability of growth and development in the region if the water supply is not accurately assessed.

The details

San Miguel officials have claimed there is a water shortage in the Paso basin in order to secure $7.6 million in grant funding from the Department of Water Resources to implement a groundwater management plan. However, the county planning commission has now approved a new 181-home development project that would rely on the same Paso basin groundwater. The project site was previously an airplane landing strip for a crop dusting operation, raising concerns about potential hazardous chemical contamination of the onsite wells that would supply the new homes.

  • In September 2018, a jury trial awarded San Miguel Community Services District 177 acre feet of groundwater annually from the Paso basin if the court found overdraft conditions.
  • In 2026, the San Luis Obispo County Planning Commission approved the new 181-home development project in San Miguel.

What they’re saying

“So which is it? Is the Paso basin in overdraft conditions limiting the amount of water available for San Miguel CSD or is there plenty of water to supply an additional 181 unit residential project.”

What’s next

The San Luis Obispo County Board of Supervisors, which oversees the Groundwater Sustainability Agency, will need to review the approval of the new development project and ensure that the water supply claims made by San Miguel officials are accurate and consistent.

The takeaway

The conflicting claims about water availability in San Miguel highlight the need for greater transparency, consistency, and accountability in the community's water management policies. Approving new development projects that may strain a potentially limited water supply raises concerns about the long-term sustainability of growth in the region.
