Water Quality Analyses (WQA) with EPA Concurrence of MDE's Findings: Greenbrier Lake

Greenbrier Lake in the Antietam Creek watershed (basin code 02-14-05-02), located in Washington County,  was identified on the State’s 1998 list of Water Quality Limited Segments (WQLSs) as impaired  by nutrients.  An analysis of recent monitoring data shows that the criteria associated with nutrients are being met, and the designated use in Greenbrier Lake is supported.  The analysis available below   supports the conclusion that a TMDL for nutrients is not necessary to achieve water quality in this case.  Barring any contradictory future data, this report will be used as supporting material when Maryland Department of the Environment (MDE) proposes the revision of Maryland’s 303(d) list for public review.  Although the waters of Greenbrier Lake do not display signs of eutrophication, the State reserves the   right to require future controls in the Greenbrier Lake watershed if evidence suggests nutrients from the basin are contributing to downstream water quality problems.
