Had no idea what this stuff was. Never would have guessed that it was a fern! Carolina Mosquitofern, an aquatic species with much-reduced fronds. Sorry for the poor photo quality; zoom shot from a bridge far above. Also present are duckweed (larger green plants; Lemna sp.?) and watermeal (tiny green; Wolffia sp.).

Azolla forms a symbiotic relationship with a nitrogen-fixing cyanobacterium, Anabaena azollae. Since that lets it obtain all the nitrogen it needs, the only limitation on its growth is phosphorus. Extensive blooms like this may thus be a sign of eutrophication from fertilizer runoff.

Description from Wikipedia

Azolla (mosquito fern, duckweed fern, fairy moss, water fern) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, looking nothing like conventional ferns but more resembling duckweed or some mosses.
