Especially noticeable at the waterfalls is the brown tea color of the water due to humic acids that originate from decaying vegetation in the headwaters.

Erosion from river banks brings soil into the river, changing its color. After heavy storms, many rivers run brown from all the runoff flowing into the river. Clay can cause rivers to be murky muddy brown, or yellow. Algal blooms are naturally occurring overgrowths of algae caused by sunlight, slow water, or nutrients.
The dark brown color in the water is nothing to worry about. This color originates from the tannins that leach from the cedar swamp at the start of the Tahquamenon River.

Dissolved organic matter, such as humus, peat or decaying plant matter, can produce a yellow or brown color. Some algae or dinoflagellates produce reddish or deep yellow waters. Water rich in phytoplankton and other algae usually appears green. Soil runoff produces a variety of yellow, red, brown and gray colors.
NO river water is considered safe to drink, ESPECIALLY large rivers that pass through cities. The Rio Plata (means 'silver river'), the 'Blue Danube', the Seine, Thames, Mississippi, Ganges, Yellow River, - all are a nice brownish colour partly due to the waste and surface drainage they still contain.
The verdant green color of the water flowing over Niagara Falls is a byproduct of the estimated 60 tonnes/minute of dissolved salts and rock flour (very finely ground rock) generated by the erosive force of the Niagara River.
Ocqueoc Falls is the largest waterfall in Michigan's Lower Peninsula and the only universally-accessible waterfall in the United States. Ocquoec provides approximately six miles of hiking, biking and cross-country skiing opportunities with three marked loops.
The Upper Peninsula's waterfalls are made up of sandstone and were formed over thousands of years. Much of the formation is due to how water falls over or on top of the rock that makes it up. Water erodes the rock over time and can create ridges and falls and a water basin by wearing down soft rock.
So you know how when you go for a dip in the ocean and you come out covered in salt crust and with the distinct stench of rotting seaweed? Yeah, that doesn't happen in the Great Lakes. The water may be colder, but it's wonderfully clean.
Lake Superior is the Cleanest and Clearest Great LakeBecause of its somewhat isolated location and long cold winters, not much farming is done along Superior's shores. This means lower amounts of nutrients, sediments, and organic material are floating around the lake.
