The Minnesota Erosion Control Association (MECA) will hold a course on winter maintenance and affiliated sediment management issues on 14 October 2009. Sediment accrual and release from winter public works is significantly more of an issue than many realize. Each year, winter sanding in the Lake Superior Watershed results in the loss of about 4500 truckloads of sand to ditches, streams, lakes and Lake Superior. The half-day course will include results from the MECA Lake Superior Basin Sediment Study.
