Comparison of Sediment Sources in Seven Mile Creek and the Minnesota River Basin - Project Summary

The Minnesota River contributes over 80% of the annual sediment load to Lake Pepin. Both Lake Pepin and many tributaries to the Minnesota River are impaired by excessive sediment loads. The Minnesota River basin is an intensive agricultural watershed, with greater than 85% of the land in row-crop cultivation. It has often been assumed that erosion of the agricultural fields is the major contributor of sediment to the river. However, confirming and quantifying this assumption on a large watershed is diffi cult, yet it is critical to targeting and implementing cost effective best management practices (BMPs).
