Summary

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2021. 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 RIM watersheds and were estimated using the WRTDS method with Kalman filtering. To determine the trend in loads, the annual load results are flow normalized to [...]

Purpose

The purpose of this data release is to provide datasets for 1985-2021 (1) Annual Loads, (2) Monthly Loads, (3) Long- (1985-2021) and Short- (2012-2021) Term Trends, and (4) 10- (2012-2021) and 5- (2017-2021) Year Average Yields. Additionally, essential WRTDS Input and Output files are provided.
