Description of the Minnesota River Basin and General Recommendations of Residue Management Systems for Sediment Control

Moncrief, John F.
This Extension Service publication discusses the higher levels of sediment load found in the Minnesota River when compared to the St. Croix and Mississippi, identifying the differences among the rivers (e.g., vegetation, agricultural activity, and soil texture) that contribute to this disparity. Recommendations are provided for tillage and manure practices that may reduce sediment runoff.

Sediment Problems and Solutions for the Minnesota River

Senjem, Norman B.
Addressing the problem of sediment in the Minnesota River, this Extension Service booklet includes a description of: sediment sources, the 40 percent reduction goal set by the Minnesota Pollution Control Agency, and tillage guidelines for reaching this goal (e.g., crop rotation, drainage, planting, fertilization, and weed control).

Minnesota River Assessment Project: Level II Land Use Analysis (South Central River Basin Study)

Soil Conservation Service
This component of the Minnesota River Assessment Project was designed to assess nonpoint pollution sources of sediment and nutrients in ten agricultural watersheds within the Blue Earth, Watonwan, and Le Sueur river subbasins. The report includes a discussion of water quality, modeling methods used in the study, pollutant comparisons among watersheds, study findings, recommendations for conservation tillage and nutrient management practices, and future study needs. Detailed analyses of each watershed are appended.
