The Post Oak Savannah Groundwater Conservation District (POSGCD) was created in Milam and Burleson counties by House Bill 1784, enacted by the 77th Texas Legislature in 2001 and confirmed through local elections in November 2002.

The purpose of POSGCD is to provide local control over groundwater resources in the central Carrizo-Wilcox area. The District’s mission includes conserving and preserving groundwater, protecting users and recharge areas, preventing pollution and waste, controlling subsidence due to groundwater withdrawal, and regulating groundwater transport beyond the District’s boundaries.
