We report the occurrence of a single population of Etheostoma parvipinne (Goldstripe Darter) in a small, acidic, spring-fed stream within the Colorado River drainage following an extended period of below-average precipitation (January–September 2011), a wildland fire (September 2011), and subsequent debris and sediment flows (November 2011–May 2012). Goldstripe Darters were taken from Alum Creek (Bastrop County, TX) along with a cyprinid, a poeciliid, and several species of centrarchids in June 2012. Occurrence of Goldstripe Darters in Alum Creek provides a regional example of fish-community responses to wildland fires. In additio n, understanding the mechanism of long-term persistence in a single tributary on the periphery of a species range might offer insight into the origin of endemic fishes and persistence of disjunct fish populations within aquatic evolutionary refugia of central Texas.
