In a recent test of three large-mouth bass from Dunlap Lake, elevated levels of mercury were found in the two largest fish (3 & 5 lbs). We are continuing to gather information and consulting with urban lake experts. We recommend anglers catch and release or follow the the Illinois Department of Public Health fish advisories which can be found at www.idph.state.il.us/envhealth/factsheets/fishadv.htm.
