Data release contains total suspended solids, total phosphorus, nitrate plus nitrite, and total Kjeldahl nitrogen concentration data for the White River at Muncie, near Nora, and near Centerton, Indiana, 1991-2017, and R source code used for model development.

Contains inputs (PeakFQ psf file and peak-flow data) to the PeakFQ program for selected unregulated and regulated streamgages in Ohio and border areas of adjacent states. Zip archive also contains PeakFQ print files for each streamgage (listed by the eight-digit streamgage identification number).

Phosphorus, nitrogen, and suspended-sediment loads, in 24 U.S. tributaries of the Great Lakes, were calculated using U.S. Geological Survey (USGS) data from the Great Lakes Restoration Initiative (GLRI) monitoring program for the period Oct 2010 through Sept 2020 (USGS water years 2011–2020). Total phosphorus, orthophosphate, particulate phosphorus, total nitrogen, nitrate plus nitrite, ammonium plus ammonia, 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 exported downstream at each tributary site....

This archive contains input files used in regression analyses to estimate concentrations and flux of total phosphorus, nitrate plus nitrite, total Kjeldahl nitrogen, and total suspended solids at selected locations on the Upper White River and output files containing annual estimates of flux and mean daily concentrations.of those same constituents, along with their 90 percent prediction intervals.
