TMDL Report: Total Maximum Daily Load for Nutrients for the Lower St. Johns River

This document presents Total Maximum Daily Loads (TMDLs) for total nitrogen (TN) and total phosphorus (TP) for the Lower St. Johns River (LSJR). The river was verified as impaired by nutrients based on elevated chlorophyll a and Trophic State Index (TSI) levels in the freshwater and marine portions of the river, and was included on Floridaís Verified List of impaired waters for the Lower St. Johns River Basin (LSJRB) that was adopted by Secretarial Order on September 4, 2003. The TMDLs establish the allowable loadings of TN and TP to the freshwater and marine portions of the LSJR that would restore the river so that it meets its applicable water quality criteria for nutrients and dissolved oxygen (DO).
