Corsica River TMDL

Final TMDLs Approved by EPA: Corsica River

The Corsica River, a tributary of the Chester River, is located in Queen Anne’s County, Maryland. The Corsica River is approximately 6 miles in length. 

The Corsica River (02130507) was identified on the State's 1996 list of water quality limited segments (WQLSs) as impaired by nutrients, due to signs of eutrophication as well as fecal coliform and suspended sediment. Eutrophication is the overenrichment of aquatic systems by excessive inputs of nitrogen and phosphorus and was evidenced in the Corsica River by high chlorophyll-a levels. For these reasons, the document available below addresses high levels of nitrogen and phosphorus, to control chlorophyll-a concentrations (a surrogate for algal blooms) and to maintain dissolved oxygen standards. A fecal coliform TMDL was completed in 2004.  The suspended sediment impairment will be addressed separately.
