Duck Creek Bioassessment Summer 2005 - Juneau, Alaska

Duck Creek is listed as an impaired water body by the state of Alaska. Four decades of urbanization in the watershed have contributed to poor water quality and loss of aquatic habitat, diminishing the creek’s ability to support fish and wildlife (Koski and Lorenz 1999). In recent years, restoration efforts have included sediment removal, channel and riparian restoration, wetland creation, and improved fish passage.

Since 1996, the stream channel between Taku Boulevard and Mendenhall Boulevard has been restored. The aquatic invertebrate community was surveyed in this reach in 1994- 1996, providing baseline information on stream health to gage the success of restoration efforts (Milner, 1996). Invertebrate communities are unique indicators of water and habitat quality because they integrate impacts from multiple stressors over time (Rinella et al. 2003). Invertebrates are also important components of aquatic food webs as they transfer energy from primary producers to secondary consumers such as fishes, waterfowl, and other birds.

This report summarizes the results of an invertebrate bioassessment on Duck Creek at Taku Boulevard and Aspen Avenue in the spring and summer of 2005. Results are compared to the baseline survey of 1994/1996.
