摘要

In 1995, personnel from the Tennessee Valley Authority discovered a population of a Chrosomus sp. in the North Fork Powell River system in Lee County, VA. Subsequent survey work revealed the species to be Chrosomus cumberlandensis (Blackside Dace). Since 1999, approximately 90 sites targeting the genus have been surveyed in the upper Powell and Clinch River systems of Lee and Scott counties, VA and Hancock and Hawkins counties, TN. Chrosomus cumberlandensis was found in two creek systems in the North Fork Powell River system and a single creek system in the Upper Clinch River system. Distribution patterns and previous genetics work suggests these populations are introduced.
