Water Quality Analysis of Eutrophication for the Youghiogheny River

Water Quality Analysis with EPA Concurrence of MDE's Findings:  Youghiogheny River

The Youghiogheny River, which flows towards the north, is a tributary of the Mononghela River that merges into the Ohio River in Pennsylvania. It is a fast free-flowing river traversing mostly mountain terrain, originating in Maryland then flowing into West Virginia, then into Maryland, then back into West Virginia and moving back into Maryland before flowing to the Youghiogheny Reservoir then moving into Pennsylvania and finally flowing into the Mononghela River in Pennsylvania. It is approximately 125 miles in length with nearly 75 miles in Pennsylvania and approximately 44 miles in Maryland and about 6 miles in West Virginia.

The Youghiogheny River (05020201) was identified on the State’s 1996 list of water quality limited segments (WQLSs) as impaired by nutrients, fecal coliform, suspended sediments, and low pH. The report available below provides an analysis of recent monitoring data, which shows that the dissolved oxygen criterion and designated uses associated with nutrients are being met in the Youghiogheny River. The analysis supports the conclusion that a TMDL for nutrients is not necessary to achieve water quality standards in this case. The report provides more recent information that supports the removal of the nutrients listing for the Youghiogheny River when the 303(d) list is revised in 2002.  A TMDL for suspended sediment impairment was completed in 2006. The fecal coliform and low pH impairments will be addressed separately.
