Abstract |
Section 303(d) of the federal Clean Water Act (the Act) directs States to identify and list waters, known as water quality limited segments (WQLSs), in which current required controls of a specified substance are inadequate to achieve water quality standards. For each WQLS, the State is to either establish a Total Maximum Daily Load (TMDL) of the specified substance that the waterbody can receive without violating water quality standards, or demonstrate that water quality standards are being met. Lake Needwood in the Rock Creek watershed (02-14-02-06) was identified on Marylands 1998 list of water quality limited segments (WQLSs) as being impaired by nutrients. |
