This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
Ninety percent of the land in Mower County is used for agriculture. The County ranks 10th and 13th in the State for corn and bean production, making much of the land vulnerable to erosion due to the planting of row crop. As a result, streams and ditches in the county see high sediment loads.
The goal of this project is to complete the construction, calibration, and validation of an Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Minnesota portions of three watersheds: Root River, Upper Iowa, and Mississippi River-Reno.
The goal of this project is to investigate nitrate transport and the sources of nitrate in karst for more effective implementation of best management practices that will reduce nitrate concentrations in ground and surface water.
