This work was conducted as part of the U.S. Geological Survey's (USGS) Integrated Water Availability Assessments (IWAAs) Program, which examines the spatial and temporal distribution of water quantity and quality in both surface and groundwater, as related to human and ecosystem needs and as affected by human and natural influences. Funding was provided by the National Water Quality Program. This data release contains all data and code needed to reproduce the results described in Schmadel and others (2024). Files include: 1. sparrow_control_IRB_TN.sas: The control file for the TN seasonally dynamic IRB SPARROW model; 2. sparrow_control_IRB_TP.sas: The control file for the TP seasonally dynamic IRB SPARROW model; 3. master_dynamic.zip: SAS source code to run dynamic SPARROW models; 4. data1_IRB.txt: text file of data inputs including calibration loads for the IRB TN and TP SPARROW models; 5. calib_list_IRB_TN.txt: text file that contains a list of the TN calibration stations; 6. calib_list_IRB_TP.txt: text file that contains a list of the TP calibration stations; 7. predict_IRB_TN.txt: text file of seasonal TN IRB SPARROW model outputs; 8. predict_IRB_TP.txt: text file of seasonal TP IRB SPARROW model outputs.
