Cherry Creek, a subwatershed of the Youghiogheny River basin, flows into Deep Creek Lake, a highly valued recreational lake in Garrett County, Maryland. Cherry Creek is part of the Western Maryland Sub-Basin. Its headwaters originate near the Savage River State Forest between the Meadow and Negro Mountains. Cherry Creek drains into Deep Creek Lake, which in turn drains into the Youghiogheny River.
TheDeep Creek watershed (basin code 05020203) was identified on the State’s 1996 list of Water Quality Limited Segments (WQLSs) as impaired by low pH and nutrients. The list acknowledged that only a portion of the watershed might be impaired, and that with additional information the spatial boundaries of the impairment could be refined. Maryland monitored the Deep Creek system more intensively in preparation for the TMDL analysis and determined that Cherry Creek, a subwatershed of the Deep Creek system, was impaired by acid mine drainage (AMD) as indicated by low pH measurements. This TMDL was developed in response to that determination. The nutrient impairment will be addressed at a later date.
