In light of MAGSA’s moratorium adopted in July, 2022 regarding well drilling through the Corcoran clay, applications to drill new wells below the clay will be directed to cease drilling when approaching the clay layer. Existing wells with depths below the Corcoran clay are not subject to restricted use.
Before submitting well drilling applications, landowners should contact MAGSA at 559-515-3339 or by email at email@example.com.
Pumping below the clay is one of the main causes of land subsidence, a gradual sinking of land caused by chronic groundwater overdraft. It is important to keep groundwater pumping above the clay to meet sustainability measures designated in MAGSA’s Groundwater Sustainability Plan.
