Current River is a clear predominantly spring-fed stream draining the southeastern face of the Ozark escarpment. Beginning at Montauk Springs, Dent County, Missouri, it meanders southward for 180 km to the Arkansas-Missouri state line. The study area containing 14 sampling stations was that part of Current River lying within the boundaries of Arkansas to its confluence with Black River. The collected fishes could be referred to as those common to a wide-ranging faunal group, the Ozark, and the lowland faunal group. Those of the Ozark group were restricted in their range by topography and the river's confluence with Little Black River. The lowland group was influenced by immigrating and emigrating fishes from Black River
