Summary

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2018. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on Time, Discharge, and Season). The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the NTN watersheds. The files containing all outputs generated by WRTDS for all applicable NTN monitoring stations are provided in the "Attached Files" section.

Purpose

These datasets contain output from the WRTDS models. These models were run to document riverine loads and trends in nitrogen, phosphorus, and suspended sediment for three time periods (depending on length of monitoring record): 1985-2018 (loads and ~30-year trends), 2009-2018 (loads and 10-year trends), and ~2010-2018 (Loads only).
