Deckers Creek is a 24.6-mile-long (39.6 km)[1] tributary of the Monongahela River that runs through north-central West Virginia. It begins west of Arthurdale and flows southeast, then north, then northwest towards Morgantown, where it empties into the Monongahela River.[2] The stream has been contaminated by various sources, though largely due to extractive resource mining and improper sewage disposal. Recently, a conservation effort has been launched and conditions are improving, as the area continues to develop for recreational purposes.
