Great Smoky Mountains National Park Threatened and Endangered Fishes

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 07, 2026 | Last Modified: 2020-11-23T00:00:00Z
These data represent visual surveys of Federally Threatened and Endangered fish species in Abrams Creek, TN, Great Smoky Mountains National Park (GRSM). These surveys are performed by employees (both seasonal and permanent), interns, and a cooperating partner, Conservation Fisheries Inc., which is based in Knoxville, TN. These data are numerical counts made visually by observers while performing snorkeling surveys within three-zones of Abrams Creek where the Smoky Madtom, Yellowfin Madtom, and Citico Darter are found. For surveying T&E fish, visual counts via snorkeling surveys are more effective than backpack electrofishing. Annual survey data are recorded in the GRSM Threatened and Endangered Fish Survey database. NOTE: Some of the ‘comments’ section in the 2020 field data sheets from these efforts list the observation of Greenside Darter and Banded Sculpin. While these native, non-game, fish aren’t considered T&E, they were extirpated from Abrams Creek at the same time as the madtoms and Citico Darter. Their reintroductions began in 2017 and appear to have been successful.
