This document proposes to establish Total Maximum Daily Loads (TMDLs) for nitrogen and phosphorus in Worton Creek. Worton Creek drains directly into the Chesapeake Bay and is part of the Upper Eastern Shore Tributary Strategy Basin. The creek is impaired by the nutrients nitrogen and phosphorus, which are causing excessive algal blooms that could violate the dissolved oxygen criterion. The water quality goal of these TMDLs is to reduce high chlorophyll a concentrations (a surrogate for algal blooms) and to maintain the dissolved oxygen criterion at a level whereby the designated uses for Worton Creek will be met. The TMDLs were determined using the WASP5.1 water quality model. Maximum loads for total nitrogen and total phosphorus entering Worton Creek are established for both low flow and average annual flow conditions. As part of the TMDLs analysis, the model was used to investigate seasonal variations and to establish margins of safety that are environmentally conservative.
