Final TMDLs Approved by EPA
The Little Youghiogheny River is a tributary of the Youghiogheny River, located in Garrett County, Maryland. The Youghiogheny River flows northward into Pennsylvania, joining the Monongahela and Allegheny Rivers to form the Ohio River. The mainstem of the river is approximately 11 miles long.
The Little Youghiogheny River (05020202) was first identified on the 1996 303(d) list submitted to EPA by the Maryland Department of the Environment (MDE). It was listed as being impaired by nutrients and suspended sediment. The actual impairment consisted of low dissolved oxygen concentrations found near the confluence of the Little Youghiogheny River and the Youghiogheny River. The Department’s analysis demonstrates that the impairment is principally due to biochemical oxygen demand (BOD) in the stream, instead of nutrients, and describes the development of TMDLs for CBOD and NBOD in the Little Youghiogheny River. MDE anticipates that these TMDLs will completely address the original 303(d) listing for nutrients. A TMDL for suspended sediment impairment was completed in 2006.
