The process is only well-documented in the Great Lakes, and has been credited with sparing the southern shorelines from worse rocky erosion.[53]. By taking CO2 out of the water to photosynthesize, diatoms help to stabilize the pH of the water, as CO2 would react with water to produce carbonic acid. Right now, the outflow, combined with evaporation both natural and man made, is larger than the inflow. Fluctuation of the water levels in the lakes has been observed since records began in 1918.

[12] There are also several thousand smaller lakes, often called "inland lakes", within the basin.[13]. Image credit: Ted Lawrence/Great Lakes Fishery Commission. The Great Lakes Waterway ( GLW) is a system of natural channels and artificial canals which enable navigation between the North American Great Lakes.

As the slightly warmer, moist air passes over the colder land surface, the moisture often produces concentrated, heavy snowfall that sets up in bands or "streamers".
