San Antonio Current

With its weedy banks and shallow waters, Lower Leon Creek looks lazy, idling beneath the willows that arch over its bends, and gently wending south towards the Medina River. It seems to be the perfect place to drop a line and wait for lunch to bite your hook.

But angling can be hazardous to your health in at least one part of Leon Creek, where some fish have tested as having 15 times the hazardous level of PCBs (polychlorinated biphenyls) set by the Environmental Protection Agency. The findings prompted the Texas Department of Health on August 27 to issue an advisory against eating any fish from a section of the creek from Highway 90 south to S.W. Military Drive, a segment that runs through the former Kelly Air Force Base and its golf course.
