Multiple cameras have been installed to take daily photographs that will monitor the Le Sueur River watershed in southern Minnesota. The Mankato Free Press reports the photos will determine where the bluffs are washing away.
The updated scrutiny is part of the ongoing research being conducted by teams from Gustavus Adolphus College, Minnesota State University-Mankato, the National Science Foundation and others. The goal is to show what factors--man-made and natural--are causing the most erosion. The work will contribute to creating a model to predict how well various control measures will work.
Findings will help guide state agencies, local groups and landowners on the best approaches to slowing sediment loads that send dirt to the Mississippi River.
The grassroots Le Sueur River Watershed Group has been working with university and state officials to develop goals for improving the Le Sueur, which is known to be a large contributor of sediment into the Minnesota River. That causes damage downsteam, including filling in Lake Pepin and carrying pollutants to the Gulf of Mexico.
