ABSTRACT: The Hatchery Creek Stream Restoration project is a unique opportunity to utilize the latest stream restoration techniques to maximize trout habitat, create recreational opportunities for the citizens of Kentucky, and provide mitigation credits. The project is located immediately downstream of the Wolf Creek Dam US Fish & Wildlife National Trout Hatchery near Lake Cumberland in Jamestown, Kentucky.
Construction of the project was completed in 2015. A 400-foot long outflow channel from the hatchery was extended to create approximately 6,000 feet of stream habitat with special attention to trout. In an effort to maximize habitat and recreational opportunities, the project was designed to provide a variety of habitat for all life stages of trout and a variety of stream types including meandering single thread channels, braided channels and step pools. This project has several unique aspects, which are not typical to natural channel design projects in the southeast, including a constant base flow of approximately 35 cfs, which is approximately 70% of the upstream bankfull flow, limited sediment supply, and the need to maintain imported spawning gravels.
Flows were released into the channel in November, 2015 and the project is currently being monitored to confirm usage for the various life stages of trout including spawning, which does not occur naturally elsewhere in Kentucky. This talk will focus on the design and construction of the channel, the many unique aspects of the project, including the introduction of an artificial upwelling device, and the initial response of the channel from a geomorphology perspective.
