Summary

Town Manager Tomas Goode told the Sonoita Creek Flood and Flow Study Committee that the town’s static groundwater level was 38 feet and town pumping averaged about 45,728 gallons per day (0.046 MGD), while a South32/Hermosa site report showed an August average of 1.1656 MGD and a maximum of 1.8377 MGD.

Town Manager Tomas Goode reported to the Sonoita Creek Flood and Flow Study Committee on Oct. 16 that the town’s static groundwater level is 38 feet and the town’s daily pumping averages about 45,728 gallons per day, equivalent to roughly 0.046 million gallons per day (MGD).

Goode also presented numbers from a South32/Hermosa site report showing a substantially higher industrial withdrawal: an August average of 1.1656 MGD and a recorded maximum of 1.8377 million gallons per day. The committee recorded the figures but took no formal action at the meeting.

Why it matters: the committee’s mission is to advise the Patagonia Town Council on managing erosion, enhancing flow and improving flood mitigation across the watershed. The discrepancy between town pumping and the South32/Hermosa site figures highlights a scale difference that committee members flagged for future discussion and monitoring.

Committee members noted the water-report item on the agenda and did not reach any policy decisions during the session. The item will remain on future agendas for monitoring and possible follow-up with the company and relevant regulators.
