Blue water lake

Blue water lake is a non-scientific term for a lake with exceptionally high-quality water whichthat, when penetrated by sunlight, appears pure blue.

Blue is one of three main lake colors, the others being green and brown. Water generally absorbs longer, red wavelengths of 600-700 nanometers. Water of the purest quality is able to absorb shorter, blue wavelengths––less than 500 nanometers––deeper into the water column, which scatter and result in the water's deep bluedeep-blue color. Lake color depends on various properties of the water body, such as nutrient load, algal growth, and overall water quality, as well as the lake's surrounding landscape. These properties, along with the lake's color, can change over time due to human activities and environmental developments. Blue water lakes have minimal amounts of pollutants, algae, and fish. They are commonly located in areas with fast drainingfast-draining soils and small lake watersheds. Lake color and clarity isare measured using a Secchi disk or underwater light sensors.

A long repeated myth is that there are only three blue water lakes in the world: West Okoboji Lake, Lake Geneva, and Lake Louise. The original source of the claim is unknown. It has been said that the claim for West Okoboji Lake originated from National Geographic, but no records can be found to support this. The list of lakes can also possibly be attributed to an early 20th centurytwentieth-century scientific study whichthat compared West Okoboji Lake to Lake Geneva. Other blue water lakes in the world include Lake Tahoe and Crater Lake. The majority of recognized blue water lakes are located in North America, specifically the United States.

There are only three known blue water lakes in the world. Lake Tahoe (California/Nevada), Lake Geneva (in Wisconsin, USA), and West Lake Okoboji (Iowa), though even these are open to interpretation. Some contend that Lake Superior and Crater Lake are also blue water lakes.

Blue Water

70% of the earth is covered with water, but only 2-3% is fresh, and still even less is drinkable - estimated as only 1% of the world's water ecosystem, according to the National Geographic. Blue water reflects wavelength of light which results in a blue appearance rather than a more common turquoise mixture of blue and green.
