Nutrient Calibration Load Estimation Data for the Puget Sound Region, 2005 through 2020
This data release contains estimated seasonal total nitrogen (TN) and total phosphorus (TP) loads during 2005 through 2020 in selected streams of the watersheds draining to Washington waters of the Salish Sea (Puget Sound region). Two load estimation methods were used: Fluxmaster (Schwarz and others, 2006, https://doi.org/10.3133/tm6B3) and Weighted Regression on Time, Discharge, and Season (WRTDS) with Kalman filtering (Hirsch and De Cicco, 2015, https://doi.org/10.1016/j.envsoft.2015.07.017). Together with the water-quality data, streamflow data, and estimated nitrogen and phosphorus loads, this release also provides copies of computer programming script that can be used to recreate the load estimates or modified for similar applications (see Process Steps). Seasonal TN and TP loads paired with streamflow were estimated at 50 locations. For convenience, seasonal summaries are also provided of observed streamflow at 128 locations and of observed water temperature at 29 locations.
