Nonpoint Pollution Sources

Interim Strategy to Reduce Nonpoint Source Pollution to the Minnesota River

Frost, Jack
This report contains an interim strategy to address nonpoint-source pollution of the Minnesota River from urban development and agriculture. The nine-point plan was intended to enable local governments and watershed-management organizations to take immediate action towards achieving the U.S. Environmental Protection Agency and Minnesota Pollution Control Agency goal of a 40 percent reduction in nonpoint-source pollution, such as watershed-planning legislation and the Board of Soil and Water Resources.

Minnesota River Assessment Project Report: Land Use Assessment

Minnesota Pollution Control Agency
This component of the Minnesota River Assessment Project was intended to identify and quantify nonpoint sources of pollution from major and minor watersheds.

Minnesota River Watershed Water Quality: An Assessment of Non-Point Source Pollution

Minnesota Pollution Control Agency- Division of Water Quality, Monitoring and Analysis Section
This study was intended to provide technical information needed to identify sources of nonpoint pollution to the Minnesota River, so that a waste load allocation study could be conducted accurately for the metropolitan segment. The report includes a description of the study area (e.g., physical characteristics, land use, and climate), study methodology (e.g., sampling), and data analysis (e.g., water-quality violations, streamflows). Study data and chart are appended.

Phosphorus in the Minnesota River

This booklet discusses phophorus pollution of the Minnesota River. Designed for use by the general public, it provides basic information on current phosphorus levels, point and nonpoint pollution sources, and various ongoing efforts to respond to the problem.

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.
