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 file containing monthly loads for all applicable NTN monitoring stations is provided in the "Attached Files" section. First posted: February 18, 2020 (available [...]

The purpose of this dataset is to communicate the monthly loads of nitrogen, phosphorus, and suspended-sediment being generated across the nontidal portion of the bay watershed.
