对大烟山国家公园的溪流进行的昼夜皮肤潜水调查显示，小河、深溪和奥康洛夫蒂河的地狱弯管虫(Cryptobrchus Alleganiensis)种群密度较低。小河种群包括发育良好的卵、鳃幼虫、幼虫和成虫，其中近50%的幼虫组成。小河是唯一一条发现泥犬(Necturus Maculosus)的溪流，由两到三个年龄段组成。水质概况显示小河和诺兰溪处于酸性状态，表明应继续进行监测工作。强烈反对在夏末和初秋使用电击和任何化学处理方法来消灭粗糙的鱼类，在那些有阿勒格尼线虫种群的溪流中强烈反对。对大小适中的阿勒加尼罗非鱼和斑点罗非鱼进行了坑内标记，以便将来进行监测，这些监测应该使用相同的昼夜皮肤潜水方法。
Diurnal skin-diving surveys of streams in the Great Smoky Mountains National Park revealed low density populations of hellbenders (Cryptobranchus alleganiensis) in Little River, Deep Creek, and Oconoluftee River. The Little River population included well-developed eggs, gilled larvae, larvae and adults, with an almost 50% larval composition. Little River was the only stream where mud- puppies (Necturus maculosus), consisting of two or three age classes, were found. Water quality profiles revealed acidic conditions for Little River and Noland Creek, indicating that monitoring efforts should be continued. The use of electro- shocking during late summer and early fall and any chemical treatments for rough fish elimination is strongly discouraged in those streams with C. alleganiensis populations. Appropriately sized C. alleganiensis and N. maculosus were PIT tagged for future monitoring which should use the same diurnal skin diving meth- od.
