Minnesota River Assessment Project (MRAP): Land Use Assessment - Level II



Minor watershed number(s):   28033, 30030, 30047, 30050, 30056, 31015, 31058, 32042, 32067, 32073

This Level II Land Use Assessment is performed on the following minor watersheds: 28033, 30030, 30047, 30050, 30056, 31015, 31058, 32042, 32067, 32073.

The Level II Land Use Analysis component of the Minnesota River Assessment Project (MRAP) was completed by the Natural Resources Conservation Service (NRCS) in 1993. The analysis assessed the extent of non-point pollution sources in ten minor watersheds located within the Blue Earth, Watonwan, and Le Sueur River major watersheds. The goal of identifying, analyzing, and recommending the most economically cost effective management implementation plan was achieved with the use of several computer models. The primary pollutants studied through computer modeling included sediment and nutrients (nitrogen and phosphorus).

Watershed Assessment

Data Summary MRAP Land Use Assessment - Level II includes data from an evaluation of the magnitude of nonpoint source pollution in these ten minor watersheds. The Minnesota Natural Resources Conservation Service completed this evaluation using computer models. The AGNPS (Agricultural Non-point Source Pollution Model) model is used to simulate sediment loading under present conditions, along with three sediment management alternatives (SED MGT- 1, SED MGT- 2, SED MGT- 3). The GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) model is used in determining levels for present conditions and nutrient management alternatives (NUT MGT-1, NUT MGT-2) using the nutrient evaluations. Input data for Land cover/Land use originated from the Minnesota River Assessment Project (MRAP) Land Use Level III. Climate records were gathered from the closest National Oceanic and Atmospheric Administration (NOAA) Cooperative Weather Station to establish a 30 year (1961-1990) annual precipitation average for each minor watershed. Evaluated minor watersheds are located within the Blue Earth, Watonwan, and Le Sueur Major Watersheds.
