Thanks NormsRevenge. Krispy Kreme ping.
A giant ring of phytoplankton (microscopic plants such as algae) was discovered in Lake Michigan in 1998 by Michigan Technological Universitybiologist W. Charles Kerfoot and his research team. The "phytoplankton doughnut" is formed when winter storms kick up nutrient-rich sediment along the southeastern shore of the lake. The disturbed sediments begin circulating in a slow-moving circle with the lake's currents, which provides a massive supply of food for phytoplankton.

I grew up with dirty farm ponds that had bluegill, maybe and bullhead catfish.

A very deprived childhood.

We did have Jackrabbits, coyotes and tumbleweeds however.
