Water Quality Analysis of Sediment for Town Creek, Allegany County, Maryland

Water Quality Analyses (WQA) with EPA Concurrence of MDE's Findings:  Town Creek

The Town Creek watershed is located in the Upper Potomac Basin in Allegany County, Maryland. The watershed covers 157 square miles of Bedford County, Pennsylvania and Allegany County, Maryland. In Maryland, the watershed covers approximately 43,409 acres in the Ridge and Valley Province, one fourth of which are preserved as state forests and game lands. Eighty percent of the watershed is forested. The rugged terrain, narrow farmable valley and lack of commercially available minerals have kept the watershed relatively undeveloped.

Town Creek (basin code 02140512) was identified on the State’s 1996 list of Water Quality Limited Segments (WQLSs) as impaired by nutrients and sediments. In 2002 and 2004, Town Creek was also listed for impacts to biological communities. The document, available below, addresses the sediment impairment in Town Creek; the nutrient impairment was addressed in 2006 via a separate report and biological impairments will be addressed at a future date.

Barring the receipt of contradictory data, the report will be used to support the sediment listing change for the Town Creek watershed from Category 5 (“waterbodies impaired by one or more pollutants requiring a TMDL”) to Category 2 (“surface watersheds that are meeting some standards and have insufficient information to determine attainment of other standards”) when MDE proposes the revision of Maryland’s 303(d) List for public review in the future.

Although the waters of Town Creek do not display signs of a sediment impairment, the State reserves the right to require future controls in the Town Creek watershed if evidence suggests sediments from the basin are contributing to downstream water quality problems.
