Final TMDLs Approved by EPA: Worton Creek

Worton Creek is located within Kent County, Maryland and is part of the Upper Eastern Shore Tributary Basin. Its headwaters originate near the intersection of Maryland’s routes 297 and 298 (Worton Park). Two smaller tributaries, Mill Creek and Tims Creek, feed Worton Creek, which itself finally drains to the Chesapeake Bay. The Worton-Mill Creek is approximately 6.5 miles (10.5 km) in length. Worton Creek alone is only 2.5 miles (4 km). 

Worton Creek, as part of the Still Pond/Fairlee Creek watershed (02130611), was first identified on the 1996 303(d) list submitted to the Environmental Protection Agency (EPA) by the Maryland Department of the Environment (MDE). It was listed as being impaired by nutrients, due to signs of eutrophication expressed as high chlorophyll a concentrations, and suspended sediment. Eutrophication is the over-enrichment of aquatic systems by excessive inputs of nutrients (nitrogen or phosphorus). The nutrients act as a fertilizer leading to excessive growth of aquatic plants, which eventually die and decompose, leading to bacterial consumption of dissolved oxygen and dissolved oxygen concentrations below what is necessary to support the designated use. For these reasons, the document available below establishes TMDLs for the nutrients nitrogen and phosphorus in Worton Creek. The suspended sediment impairment will be addressed separately.
