The Huron River was crawling with volunteers and stoneflies on Saturday, from White Lake to Flat Rock (near Lake Erie), in order to give the river system its annual check-up. The instruments for this kind of check-up included pickaxes to break through the ice and nets to scoop up the bugs. Many of the volunteers were surprised at “… the amount of life in a frozen stream.” More photos are here. Go here to read an account of the day.
