Data were collected to determine the abundance of nitrogen-fixing microorganisms in Cladophora algae growing on rocks, breakwall structures, or submerged dreissenid mussel beds around southern Lake Michigan. Cladophora samples (N=33) were collected between June and September 2015 from three urban areas: (a) Jeorse Park, East Chicago, Indiana, (b) Calumet Beach, Chicago, Illinois, and (c) North Beach, Racine, Wisconsin, and a National Park site, Portage Lakefront, Indiana Dunes National Park, Indiana. Corresponding lake water samples (N=33) were collected approximately 15-20 feet away from submerged algal mats. Genomic DNA was extracted from water and processed algal samples. The abundance of nitrogen-fixing microorganisms...
