Abstract |
Duck Creek is listed on the 1998 303(d) list of impaired waters in Alaska for residues, in the form of debris. The primary source of debris in the watershed is littering, which delivers wood scraps, plastics, and other solid wastes directly to the creek and makes them available for transport to the creek by wind, storm water runoff, and snowmelt events. The water quality standard for residues prohibits any anthropogenic debris to Duck Creek in order to protect designated uses of water supply, water recreation, and growth and propagation of fish, shellfish, other aquatic life, and wildlife. It is recommended that local agencies, community groups and/or volunteers continue to conduct regular clean-ups of the stream and track and publicize the types and quantities of debris removed from the creek. Citizen education also will help to inform the public about the potential adverse effects of littering and to foster a sense of stewardship in Duck Creek watershed residents. |
