During heavy rainfall in October 1998, the roof and sides of a Koch 50,000 barrel above-ground storage tank buckled, discharging approximate 963 barrels of crude oil into Marcelinas Creek, which is a tributary of the San Antonio River. The spill occurred 1 mile northwest of Falls City, Karnes County, Texas, and entered Marcelinas Creek at flood stage. The spill was generally contained about three miles downstream. The floodwaters transported the oil laterally well beyond the banks of the creek, coating vegetation in these areas with oil as the floodwaters receded. The three miles of creek and adjacent riparian corridor, consisting of mature hardwood trees and improved pasture, provide essential habitat to numerous species of fish, birds, mammals, and reptiles. The Trustees have completed their assessment and are working to identify restoration alternatives in cooperation with the responsible parties.
