RESPONSE OF FISH AND MACROINVERTEBRATE COMMUNITIES TO A NOVEL STREAM RESTORATION IN CENTRAL KENTUCKY
Hatchery Creek is a restored tailwater stream stemming from the outflow of Wolf Creek National Fish Hatchery southwest of Jamestown, KY. The original channel of Hatchery Creek had degraded over the last 40 years and has caused water quality issues in the lower Cumberland River due to sediment. A 6-km novel channel was constructed to reduce sediment delivery and create a self-sustaining trout population. We predicted that the improved hydrologic and habitat conditions would benefit fish and macroinvertebrate communities. Fish and macroinvertebrate communities were sampled seasonally for 2 years before and after the reconstruction. Taxa richness was the only macroinvertebrate metric that significantly increased from 12.83 ± 0.48 to 15.76 ± 0.42 (p=0.0029). The fish community significantly decreased in taxa richness from 7 ± 1 to 3 ± 0.28 (p=0.0019), but significantly increased in density (p=0.037). Hatchery Creek provides a unique opportunity to examine synthetic stream channel restorations and to quantify habitat improvements independent of water quality. Initial patterns show a mix of positive and negative responses to the increases in habitat quality and indicate that community recovery may need more time.
