The goal of this project was to determine what different areas of the landscape contribute sediment to the Le Sueur River. More specifically, the goal was to determine the relative sediment contributions from upland agricultural fields versus bluffs and ravines.
The project applied new sediment fingerprinting techniques (meteoric 10Be) and provided an extensive sediment survey. This survey evaluated all major sources including bluffs, upland agricultural fields, upland forested areas, ravines, floodplains, and stream banks. Information from this project will help target conservation practices to areas that contribute the largest amounts of sediment.
A final report as well as a detailed description of all projects is located at the Minnesota Department of Agriculture's Clean Water Fund website.
About the Issue
This project was supported by the Minnesota Department of Agriculture's Clean Water Research Program. The overarching goals of this research program are to identify underlying processes that affect water quality, to evaluate the effectiveness of agricultural Best Management Practices, and to develop technologies to target BMPs to critical areas of the landscape.
MDA funds research that is necessary to protect water resources in Minnesota. All projects are selected by an evaluation team.This team includes a diverse group of external stakeholders and state agency staff that have technical expertise and a broad understanding of water quality issues.
In 2008, a total of 12 projects were submitted totaling $1,700,000 in requested funds. The evaluation committee recommended that the top five projects be funded. An additional three projects were selected for sole source contracts. These projects were identified as high priority needs that required specific expertise and resources to effectively address the research question.
