Overlapping in parts is the Edwards-Trinity Aquifer, a major system underlying much of the plateau with limestone and sandstone layers, providing essential groundwater for irrigation and municipal use.

Edwards Aquifer History and Conservation

The Edwards Aquifer history traces back millions of years to ancient seas, with modern management beginning in the 1990s through entities like the Edwards Aquifer Conservation District and the Edwards Aquifer Authority, established to regulate pumping and protect flows.

Edwards Aquifer Pollution and Endangered Species

Concerns over Edwards Aquifer pollution from urban runoff and development highlight the need for vigilant protection. The aquifer is home to unique Edwards Aquifer endangered species, including the fountain darter and Texas blind salamander, which rely on pristine spring flows.

Preserving the Edwards Plateau: The Role of the Edwards Plateau Alliance

The Edwards Plateau's natural beauty, water resources, and ecological diversity face ongoing challenges from development pressures. Organizations dedicated to its stewardship play a critical role in safeguarding this irreplaceable region. The Edwards Plateau Alliance is a community-driven group focused on protecting the land, water, families, and environment of the Edwards Plateau. With education at the heart of its mission, the alliance informs the public about the impacts of large-scale infrastructure projects—such as high-voltage transmission lines—on the region's ranches, rivers, wildlife habitats, and water systems.

Through advocacy, community organizing, and calls for sustainable alternatives, the Edwards Plateau Alliance works to preserve the plateau's heritage and resources for future generations, emphasizing collective action to address threats like habitat fragmentation, soil erosion, and potential pollution runoff.
