“The Great Lakes are far cleaner today than in 1970 as a direct result of the Clean Water Act,” said Brammeier.

Pollution from over a century of intensive development remains in the sediment of many Great Lakes tributaries, harming fish and wildlife and leaving water unsafe for people. These sites are being cleaned up through the Great Lakes Legacy Act by the U.S. EPA in partnership with local, state, and private organizations.
The Great Lakes are struggling under the combined weight of many ailments, from invasive species and toxic chemicals to the nutrient runoffs that fuel Lake Erie's chronic algae problem. And in many cases, climate change is making it worse.
Swimmers didn't find it too appealing, but it was popular for those who wanted to fish for trout. However, an analysis of satellite images between 1998 and 2012 showed that Lake Michigan and Lake Huron are now clearer than Lake Superior, which had always been the clearest of the Great Lakes in the past.
NOAA works through the Great Lakes Restoration Initiative to improve fish passage, clean up debris, restore coastal wetlands, and remove invasive species in the Great Lakes region.
According to the average of their simulation ensemble, by 2040–2049, the average annual water levels of Lake Superior, Michigan-Huron, and Erie are projected to increase by 0.19, 0.44, and 0.28 m, respectively, relative to 2010–2019 under the Representative Concentration Pathway (RCP) 8.5 scenario.
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.
Lake Superior is the world's largest freshwater lake by area (31,700 mi2 /82,100 km2). It is also the coldest and deepest of the Great Lakes, with a maximum depth of 406 meters (1,332 feet). By most measures, it is the healthiest of all the Great Lakes.
Lake Michigan's riptide and longshore tides are unparalleled when it comes to danger among all the Great Lakes. In fact, due to its unnaturally strong winds, it's not unusual for this lake to have strong rip currents that can be dangerous for swimmers.
Lake Superior declined 2 inches from November 30, 2022 to December 30, 2022. This is a fairly typical amount of water decline for December. It represents what sounds like a bunch of water: one inch of water on Lake Superior equally 550 billion gallons of water.
Those findings are consistent with a study from Michigan Technological University. That study found Lake Superior is expected to rise on average by 7.5 inches while levels on the Lake Michigan-Huron system is projected to increase 17 inches by 2050 due to climate change.
Geology of Lake InferiorLake Inferior is an underground lake that is located beneath Lake Superior. It is believed to be formed by a process known as karstification, which is the dissolution of limestone and dolomite rock. This process creates sinkholes, caves, and underground rivers and lakes.
No. People are not capable of changing things on that scale. We could easily pollute the water and make it undrinkable, but we can't drain the lakes, because there is just too much water there, and it's constantly refilled from too many sources, including rain and snow melt.
10% of the entire planet's fresh water are contained in one inland sea. The amount of snow that gets melted and runs into the Great Lakes each year is so vast, that there is zero chance of running low. Droughts don't exist up there. Here in Perth Western Australia we have a dam, little rain and treated water.
Lake Erie is the fourth-largest lake in North America (by surface area) and the eleventh-largest worldwide. It is the Great Lakes' southernmost, shallowest, and smallest by volume. By the 1960s, Lake Erie had become the most polluted of the Great Lakes, owing to the substantial industrial presence along its coasts.
Lake Superior is the largest of the Great Lakes by surface area and volume. It is like a mini-freshwater ocean, you can't even see the other side from the Wisconsin shoreline.
Lake MichiganThe Great Lakes are all water bodies that swimmers should think twice about entering. Lake Michigan in particular is the roughest of the Great Lakes, and poses a major risk to those thinking of taking a dip. This body of water is often named the most dangerous lake in the United States.
Lake Superior is the world's largest freshwater lake by area (31,700 mi2 /82,100 km2). It is also the coldest and deepest of the Great Lakes, with a maximum depth of 406 meters (1,332 feet).
These lake surface temperatures are projected to rise by as much as 7°F by 2050 and 12.1°F by 2100. Higher temperatures, increased precipitation, and lengthened growing seasons are likely to result in increased production of blue-green and toxic algae in the lakes.
