Final TMDL Report: Nutrient TMDL for Arlington River, WBID 2265A

This report presents the Total Maximum Daily Load (TMDL) for nutrients for the Arlington River in the North Mainstem Planning Unit of the Lower St. Johns Basin. The river was verified as impaired for nutrients during the Cycle 1 assessment and was included on the Verified List of impaired waters for the Lower St. Johns Basin that was adopted by Secretarial Order in May 2004. Based on a total nitrogen (TN)/total phosphorus (TP) median ratio of 8.8 during the Cycle 1 verified period (January 1, 1996–June 30, 2003), nitrogen was identified as the limiting nutrient. Since there were insufficient chlorophyll (chla) data to demonstrate whether the nutrient criterion was being met during the Cycle 2 assessment period, the Arlington River remained on the Verified List for nutrients. This TMDL establishes the allowable loadings to the Arlington River that would restore the waterbody so that it meets its applicable water quality criterion for nutrients.
