50 miles North of Chattanooga, a thumb-sized anomaly swims between the rocks and moss of the small streams on Walden Ridge. To the unknown eye, these fish, known as the Laurel Dace, could easily be overlooked or mistaken for any other small freshwater fish that is found in East Tennessee. The rarity of the fish doesn’t come only from their size and characteristics, but the extremely specific area they are found. Since their discovery in the 1950s, the Laurel Dace have only been found in one location in the world, Walden Ridge. 

The limited environment the Laurel Dace inhabit causes an extremely small population to begin with. In 2011, the U.S. Fish and Wildlife Service officially listed the Laurel Dace as endangered under the Endangered Species Act (ESA). From first discovery, this species was found in only nine streams at Walden Ridge, but over the past 25 years, that number has shrunk drastically.  Over several decades, because of continued agriculture, dry seasons, and increased sedimentation, the Laurel Dace are now only seen having a healthy population in Bumbee Creek on Walden Ridge.

Once the fish were recognized as critically endangered, the Tennessee Aquarium and the Tennessee Aquarium Conservation Institute (TNACI) stepped in and began their preservation efforts. Over time, the TNACI continued to keep a close eye on the Laurel Dace by studying their environments and behaviors. Several rescues have been conducted where teams would go to Bumbee Creek and take several fish into their care for further monitoring and research. Through their ongoing observations in the wild, the TNACI was also able to take fast action to save the Laurel Dace when circumstances became drastic.
