While Louisiana has stunning natural scenery and abundant recreational activities, this southern state ranks as one of the worst in the country for polluted water. Over 11 million pounds of toxic chemicals find their way into Louisiana bodies of water, with the Mississippi River and Lake Maurepas being some of the most dangerous in the state. Because exposure to dirty water can increase your likelihood of cancer and reproductive damage, finding a clean lake to fish, swim, and boat is essential. Check out these picks for the top seven cleanest lakes in Louisiana and how you can enjoy them.
