The 17,351-acre Powderhorn Ranch in Calhoun County, one of the few remaining large tracts of intact native coastal prairie and wetlands on the Texas coast, will become a state park and wildlife management in the wake of a cooperative effort between private conservation groups and the state's parks and wildlife agency that uses $34.5 million in settlement fees from the 2010 Deepwater Horizon explosion and resulting oil spill to help fund the property's $37.7 million purchase price.
