Louisiana DEQ online map: Don't eat fish caught here, don't swim there

A recently created interactive map lets people know if pollution has made a Louisiana waterway unsafe for swimming, and tells anglers whether it's safe to eat their catch.

The map shows 58 lakes, bayous and other waterways where contaminated fish have been caught, the bottom is too polluted for safe swimming, or both. Most restrict fish or shellfish eating; two also warn against swimming. Two others warn only against swimming.

The largest advisory covers all state waters in the Gulf of Mexico — nearly 1,200 square miles (3108 sq. kilometers).

Clicking on a fish-and-fish-hook icon brings up the advisory. Zoom in and larger bodies of water in affected areas show up in dark blue. Those areas also are clickable, but are approximations — adjacent areas of dark and light blue aren't boundaries, Department of Environmental Quality scientist Al Hindrichs said in an email Friday.
