The objectives of this study are the following: (1) to assess water-quality differences within the Cumberland River using aquatic macroinvertebrates as bioindicators, (2) to note seasonal and distributional differences in the aquatic macroinvertebrate community throughout the sampled area, and (3) to establish baseline information on the aquatic macroinvertebrate community for future biomonitoring of the river.
The tailwater of the Cumberland River was sampled at five sites along its length in May 1999, August 1999 and February 2000. Macroinvertebrates were collected from a variety of habitats utilizing Kentucky Division of Water aquatic sampling protocols. Data derived from these collections indicated impaired conditions highly dissimilar from local free-flowing streams of comparable size. Conditions were most degraded at site 1, immediately below the dam. At this location, few sensitive taxa were found. Instead, it was inhabited by specialist taxa such as amphipods, chironomids and oligochaets, which are known to occur in high density below deep-release dams. In general, taxa diversity and various other metrics indicated a recovery zone beginning at site 2 (18.5 km downstream of the dam). In these lower reaches, sensitive taxa in the Ephemeroptera, Plecoptera and Trichoptera (EPT) indices showed increasing abundance downstream, peaking at site 4 (62.8 km downstream from the dam). An anomaly in this trend occurred at site 3 (41 km downstream from the dam) which showed a more impaired and less stable condition than would have been expected. This was likely due to the impact of Crocus Creek, which joins the tailwater just upstream of this sample site. Much of the lack of diversity in the Cumberland River Tailwater system overall is likely due to the altered thermal regime imposed by the hypolimnetic source of the Cumberland's water. Namely, temperatures show less variability and lower summer maxima than would be found in similar-sized free-flowing streams. These thermal irregularities along with fluctuating flow levels and high current velocities make the tailwater an inhospitable place for many aquatic organisms.
