Final TMDLs Approved by EPA: Manokin River

The Manokin River is located in Somerset County, Maryland. It drains directly to the Chesapeake Bay roughly 4.5 miles due east of South Marsh Island. The River is approximately 15 miles in length, from its confluence with the Bay to the upper reaches of the headwaters.  Two restricted shellfish harvesting areas are located within this basin:  Manokin River (on the northeast side of the Manokin River) and St. Peter's Creek (slightly located to the west of the Manokin River area).  The shellfish harvesting restricted area of the Manokin River is located about 10 km from the Manokin River mouth and has a length of approximately 12 km from northeast to southwest and a width of approximately 2 km from north to south near the mouth.  St. Peter’s Creek is located approximately 10 km from the Manokin River mouth and has a drainage area of 2,032.1 acres (8.2 km2).  St. Peter’s Creek has a length of approximately two km and a width of approximately 0.3 km.

The Manokin River Basin (basin number 02130208) was first identified on the 1996 303(d) List submitted to EPA by the Maryland Department of the Environment (MDE) as impaired by bacteria, sediments, and nutrients.  On the 2004 303(d) List, the fecal coliform impairment was clarified with the identification of two specific shellfish harvesting areas within the basin.  The document available below addresses the fecal coliform listings of the two restricted shellfish harvesting areas:  Manokin River and St. Peter’s Creek.  The suspended sediment impairment will be addressed at a future date.  A TMDL to address the nutrient listing was approved in 2000.
