Minnesota River BMPs to Reduce<br />
Phosphorus<br />
This project involved planning, targeted education and<br />
implementation that led to improved water quality<br />
with construction of BMPs in riparian and other near<br />
shore, critical areas that reduced bacteria, sediment,<br />
P and other pollutants. The project’s planning and<br />
education efforts were important steps in achieving<br />
long-term water management goals. Direct education of<br />
landowners and local government officials will improve<br />
adaptive management skills in critical areas beyond<br />
the project period. Project goals were consistent with<br />
TMDL implementation plans and TMDL studies that are<br />
underway. The project work plan complements other<br />
efforts to address these and related concerns in BEC.<br />
This project ran concurrently with two State FY 2011<br />
Clean Water Fund projects until December 31, 2012.<br />
Consistent with the 319 RFP at the time of application,<br />
a portion of State grants and loans were used to match<br />
the 319 grant. This project also complemented a Hazard<br />
Mitigation Plan update project.<br />
Goals<br />
• Install BMPs in the riparian areas to reduce erosion<br />
and run-off containing livestock manure, phosphorus,<br />
bacteria and sediment<br />
• Eliminate direct sewage discharges to reduce<br />
phosphorus and bacteria reaching surface waters<br />
• Identify and prioritize major sources and sites of ravine,<br />
stream bank and bluff erosion in BEC<br />
Results that count<br />
• One hundred and ninety landowners installed<br />
vegetated buffers on 6,605 acres. One landowner<br />
installed a grade stabilization structure. It is estimated<br />
that the following pollution reductions were achieved<br />
per year for the grade stabilization structure: 194.77<br />
tons of soil saved, 207.19 tons of sediment reduced,<br />
and 227.94 lbs of phosphorus reduced.<br />
• Fifty-nine SSTS upgrades were completed. Using BWSR<br />
Calculators it is estimated that the following pollution<br />
reductions were achieved per year: 13,970 lbs of TSS,<br />
626 lbs of phosphorus, 1,925 lbs of nitrogen, 25,290 lbs<br />
of biochemical oxygen demand (BOD), and 3.658 E+15<br />
Bacteria most probable number (MPN).<br />
• Over 800 actively eroding ravine, stream bank and bluff<br />
erosion sites were identified. Twenty-two locations<br />
were followed up with landowner/field visits. Eight of<br />
those locations are working with future grant funds to<br />
be fixed.<br />
