Powderhorn Keeps a Big Piece of Coastal Prairie in Public Hands
Powderhorn sits near Port O'Connor, where prairie, marsh, oak trees, and bay water crowd together. The roughly 15,000-acre wildlife management area reaches along Powderhorn Lake and Matagorda Bay. Its mix includes fresh and brackish wetlands, tall coastal grass, and live oak mottes.
This is not a paved picnic park. Public use runs through scheduled birding, tours, and public hunts. Camping is not available on the WMA. That slower access fits the place. Powderhorn protects habitat before it tries to be a visitor stop, and that restraint is part of why the tract feels valuable.
TPWD manages the tract first as wildlife habitat. Restoration work has returned about 7,200 acres to native coastal prairie, and that work continues. For Calhoun County, Powderhorn keeps a large public piece of the bay side under conservation management.
The place also helps explain why Port O'Connor is not just a fishing dot on the map. It sits beside a large stretch of grass, wetland, lake edge, and bayfront habitat. That mix is a big part of the county's coastal feel, and easy to remember.
