The primary data sets consist of continuous water-quality data (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate plus nitrite, and streamflow) from in-situ equipment, and discrete water-quality samples (total nitrogen, total phosphorus, suspended sediment concentration, and suspended sediment sieve diameter) collected during site visits at the USGS streamgage School Branch at CR750N at Brownsburg, Indiana, November 17, 2015 to February 6, 2019. The continuous and discrete measurements were used to develop regression models which may be used to compute concentrations and loads of suspended sediment, total nitrogen, and total phosphorus. The secondary data sets consist of daily streamflow, daily turbidity, daily specific conductance, and daily nitrate plus nitrite values collected continuously by in-situ monitors at School Branch at CR750N at Brownsburg, Indiana June 23, 2015 to February 6, 2019 which serve as input explanatory variables for the developed regression models to compute suspended sediment, total nitrogen, and total phosphorus at School Branch at CR750N at Brownsburg. The tertiary data sets for June 23, 2015 to February 6, 2019 are the output data sets that were developed by application of each regression model and include the computed daily mean constituent concentrations (with upper 95-percent prediction interval, and lower 95-percent prediction interval) and daily mean constituent loads (with upper 95-percent prediction interval, and lower 95-percent prediction interval).

The data set consists of continuous water-quality data (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate plus nitrite, and streamflow) from in-situ equipment and discrete water-quality samples (suspended sediment concentration, suspended sediment sieve diameter, total nitrogen, and total phosphorus) collected during site visits at the USGS streamgage Kankakee River at Shelby, Indiana (05518000) from January 2016 through May 2018.

This data release contains the calibration data set and R code used to create regression models for estimating daily loads of suspended sediment, total nitrogen, and total phosphorus at the Iroquois River near Foresman, Indiana streamgage (05524500). The USGS R software package, rloadest, was used to develop the regression models and estimate loads. The models were developed using discrete water-quality data and concurrent daily streamflow data measured/determined at the streamgage for the period April 2015 through July 2018. Also included in this data release is the input data set of daily streamflow data and the daily load output data sets that were produced by the regression models. Summary information for the model development for each constituent are included in this data release.

The primary data sets consist of loads (with upper 95-percent prediction interval, and lower 95-percent prediction interval) of suspended sediment, total nitrogen, and total phosphorus calculated from instantaneous concentrations estimated from regression models from June 23, 2015 to February 6 2019. The secondary dataset consist of daily loads calculated from the cumulative total of instantaneous loads for each day in the primary dataset.

This data release contains data sets and R code used to create regression models for estimating daily flux of suspended sediment, total nitrogen, and total phosphorus at the Kankakee River at Shelby, IN (05518000) streamgage. The models were developed using discrete water-quality data and concurrent daily streamflow data measured/determined at the streamgage for the period January 2016 through May 2018. Also, included is a daily streamflow input data set and daily flux output data sets that were developed by application of the regression models. The USGS rloadest package was used to develop the regression models and flux estimates. Summary information for the models for each constituent are included in this data release.

This dataset describes baseflow and stormflow concentration data for the constituents of nitrogen and phosphorus and suspended sediments for watersheds included in a paired watershed study including a forested reference watershed and three urban watersheds with centralized or decentralized stormwater management in Clarksburg, Maryland USA. Surface water samples were collected between the years 2004-2016. These data are interpreted in a journal article published in the Journal of Environmental Management.
