We have advisories around my neck of the woods in creeks and rivers not for just consumption but E-Coli. Lots of zinc mining in this area years ago, a few Superfund Cleanup sites as well. The creeks are very inviting for recreation but a recent study showed extremely high levels of E-Coli from field runoff, septics, etc... Advisories are in place to not even swim in these areas. BUT... A buddy and I went to Turkey Creek after work yesterday for some wade fishing (I know sounds stupid!) Caught Largemouth up to 17", channel cat up to 18", various bluegill, rock bass, punkinseeds, and a 13" smallmouth. These fish were very healthy looking. Where the sun hit the water fish could be seen everywhere. Of course nothing was going to be eaten, but if someone didn't know of the advisories, I'm curious as to how ill one could become by eating one meal of fish from E-Coli contaminated water. Or swimming in it for that matter. Very interesting quality of fish as well. I did take a long hot shower afterwards!
