Final TMDLs Approved by EPA: Lake Roland

Lake Roland is a 100-acre impoundment in the middle portion of Jones Falls, a tributary to the Patapsco River. Two smaller tributaries, Roland Run and Towson Run, also feed the lake. Lake Roland lies in the Patapsco/Back River Basin within the Jones Falls watershed (02130904). 

Chlordane, a pesticide no longer authorized for use in the United States, has been detected in certain Lake Roland fish tissues at levels requiring issuance of a fish consumption advisory. This advisory has been in place since February 5, 1986. As a consequence of the fish advisory, Lake Roland (in the Jones Falls Watershed) was identified as a water quality limited segment (WQLS) on the 1996 additions to Maryland’s 303(d) list. The report available below documents the establishment of a chlordane TMDL for Lake Roland.
