The Adirondack Lakes in New York is one of the most well-documented case studies for freshwater acidification. As early as the 1970s, it was showing signs of acidification due to low values of acid ANC (Acid Neutralizing Capacity) industrial emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), resulting in acid rain.

Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life ...
These substances rise very high into the air, mix with and react with water, oxygen, and other chemicals to create acid rain pollution. The effects of acid rain are mostly seen in aquatic ecosystems. As the rain flows through the soil, the acidic water can drain away aluminum from the soil and them flow into streams and lakes.
"Work at the ELA has produced important evidence on the effects of acid rain and led to the discovery that phosphates from household detergents cause algal blooms. It has elucidated the impacts on fish of mercury and shown how wetland flooding for hydroelectricity leads to increased production of greenhouse gases." [11]
Scientists have observed that many lakes are becoming less clear while also recovering from acid rain. This phenomenon has been seen in the northeastern United States and northern Europe. In the past, some lakes were ecologically bare, yet clear, while acidity was high.
Indiana's decisions also could affect wildlife throughout the watershed, Boritt said, including the more than 80 species of Great Lakes fish that rely on wetlands to spawn, feed or protect their ...
Lakes and ponds can be very large and support a complex eco-system in which environmental parameters vary widely in all three physical dimensions and with time. Large lakes in the temperate zone often stratify in the warmer months into a warmer upper layers rich in oxygen and a colder lower layer with low oxygen levels.
A wintry blast is slamming the Great Lakes region with 3 to 5.5 feet of snow -- and more lake effect snow is in the forecast for later this week. Monday's intense lake effect snow band from Lake ...
