I am wading in the lifeblood of Michigan, the Au Sable River. My left arm tenses as I cast. I'm not a lefty, but the temporarily useless right hand won't be able to reel in a fish for at least a month. Still, it's not a fruitless exercise, it's water therapy — good for the body and soul.
As I gaze at the flow an Isonychia dun drifts by. I wonder how the waters will change — the Michigan Department of Environmental Quality approved a permit in July 2014 for a local fish farmer to add millions of gallons of fish feces effluent to this pristine fishery.
Dan Vogler of Harrietta Hills Trout Farm, LLC plans to increase production of the Grayling Fish Hatchery, situated on the East Branch of the river, from 20,000 pounds of fish biomass a year to 300,000.
It is a flow-through facility, with all fecal matter and any potential pathogens flowing out of the fish farm and directly into the river.
