Final TMDLs Approved by EPA: Wicomico River

The Wicomico River is located in Wicomico County, Maryland. The River is approximately 18.8 miles in length, from its confluence with the Ellis Bay and Monie Bay to the upper reaches of the headwaters. 

The Lower Wicomico River (02130301) was identified on the State’s 1996 list of water quality limited segments (WQLSs) as impaired by nutrients (nitrogen and phosphorus), fecal coliform and suspended sediments. Subsequent investigation determined that nitrogen, phosphorus, and biochemical oxygen demand (BOD) are the dominant causes of high algal levels and low dissolved oxygen concentrations. The report available below establishes three TMDLs for the Lower Wicomico River: one for nitrogen, one for phosphorus, and one for BOD.  The fecal coliform and suspended sediment impairments will be addressed separately.
