ADEM Complaint Department
If you see a pattern of possible pollution/“slicks” on the lake, you may want to keep a record & submit this record to ADEM (Alabama Department of Environmental Management) - if they receive a number of complaints, they’ll likely investigate.
As citizens on the water, you’re most likely to detect early stage water issues.
