Range Description

This darter occurs in the Cumberland River drainage above Cumberland Falls in eastern Kentucky (Strange 1998) and adjacent Tennessee (USFWS 2011). Recent surveys by O'Bara (1988) and Laudermilk and Cicerello (1998) indicate that the Cumberland Darter is restricted to short reaches of 16 small streams in the upper Cumberland system in Whitley and McCreary counties, Kentucky, and only two small streams in Tennessee (one in Scott County and one in Campbell County). The species has apparently been extirpated from Little Wolf Creek, Whitley County, Kentucky, where it was recorded by Jordon and Swain (1883), and Gum Fork, Scott County, Tennessee, where it was recorded by Shoup and Peyton (1940). Also, although O'Bara (1988) recorded the Cumberland Darter from two sites in the mainstem of the Cumberland River, recent efforts to recollect the species from these sites have been unsuccessful (Ron Cicerello, Kentucky Nature Preserves Commission, Frankfort, Kentucky, personal communication, 1999). Previous records of the species in the Poor Fork portion of the Cumberland River drainage in Letcher and Harlan counties, Kentucky (Starnes and Starnes 1979), have been determined to be the Johnny Darter (Etheostoma nigrum) based on a genetics study conducted Strange (1998). Records of the species from Martins Fork, Harlan County, Kentucky (Starnes and Starnes 1979), are also believed to misidentifications; however, efforts to collect individuals from Martins Forks for genetic studies have been unsuccessful, indicating that whichever taxon occurred in this system has apparently been extirpated.
