Sturgeon Bay

[2] The bay seems to represent the pre-glacial path of the Menominee River, with the valley deepened by glacial carving and then submerged into rising lakewaters.

[4] Researchers collected viral hemorrhagic septicemia viruses from 184 different fish from 2003 to 2017.

Each of them was a different variant of a type not found in the middle or lower Great Lakes.

This was the result of an experiment to stock millions of eggs from the species Hexagenia limbata and Hexagenia bilineata in the lower Green Bay area in an attempt to reintroduce the species.

The last mayfly from the genus Hexagenia had been collected in the lower Green Bay area in 1955.
