SPADRA BASIN GROUNDWATER SUSTAINABILITY AGENCY

In response to SGMA, the Spadra Basin Groundwater Sustainability Agency (Spadra GSA) was formed February 28, 2017 by the Walnut Valley Water District and the City of Pomona... The Spadra Basin is a groundwater basin located in the San Gabriel Valley, in the western portion of the City of Pomona. The basin lies near what used to be the bustling town of Spadra, located on an important historic stagecoach travel route. Today, the Spadra Cemetery and the Phillips Mansion, owned by the Historical Society of Pomona, are all that remain of the town.
