re: Chicot State Park advice needed

2 years ago we camped in the north camp ground when we went to the landing to launch the boat there was a sign saying dont eat the fish cause of lead or something we fished for a few days and in that time caught a few bass and sacs a very small few. The fishing was bad but its pretty on the lake it was middle of the week and quiet and fun. We were very disappointed about the sign and after the wife read it there was no talking her into taking fish back to camp cleaning and frying them. Aint been back. Love the camp ground and walking and biking but aint bringing my boat again specially with the occasional comments I see here.
