Abstract

This repository contains data for HUC 8 priority watersheds in the Mississippi River Basin core states (Arkansas, Illinois, Indiana, Iowa, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, Ohio, Tennessee, Wisconsin). Nitrate monitoring data in receiving streams and rivers in each priority watershed from 2000-2015 was collected from Water Quality Portal. Watershed metadata are included in the PriorityWatershed_Metadata file. Results of time series analysis (Seasonal Mann-Kendall test) for watersheds with sufficient data are detailed in SMK_results, SMKmonth_results, and SMKmonth_Trend_results files. All analyses were conducted in R within the attached R script file.
