Deckers Creek is a 24.6-mile-long (39.6 km) 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. 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.
