Think of the fish as a water filter what goes into the water goes into the fish. I don't live in your area but the same applies. Be careful of eating fish after periods of rain, because the storm sewer will fill up and goes into the raw sewer then discharges into the river. Your DNR should have pollution stats for the section of river you fish. Also when cleaning fish out of a river take care to remove all fatty tissue from fish because this is where toxins are stored. Just talk to people that eat fish out of there and see if they have any weird medical conditions from eating fish. IE third eye or something.LOL
