Lake Tahoe has reportedly flipped , and while we ’d love to describe that it ’s just stuck the landing on a very wet 360 , the realities of lake turnover rate are a piffling more nuanced . Lakes flip like this can materialise episodically each year and are a raw and normal phenomenon that come with the tot up welfare of give aquatic animal a tonic flush of oxygen and food .
The flipping , or mixing , of Lake Tahoe was reportedly completed sometime around previous February , says UC DavisTahoe Environmental Research Center(TERC ) in a spell forYubaNet . We know this because their enquiry teams have been sample the lake ’s water weekly , which enable them to get data on the piddle ’s quality and health , as well as what phytoplankton are swirling around in the mixture .
Lake flipping , more conventionally known as lake turnover , is facilitate by the wind and can see vast quantities of water in effect turn over so that the layers become an even mix . Imagine suck into a B52 shot and watching its define layer get all messy . Lake flipping is fundamentally the same , just without all the alcohol .

In lakes , those layers constitute different temperatures of water and in true scientific jargon way , they have some intriguing and difficult to pronounce names :
The summersault , as you may opine , is moderately slow . Driven by malarkey and air temperature change , it look the defined layers of the lake ( know as stratification ) disappear as water mixes and turns over . Once the employee turnover is complete , the lake will theoretically be the same temperature top to bottom .
Flipping begin in tumble for Lake Tahoe , and see the surface water cool down and sinking further and further as the seasons progressed into the winter . By February 1 , flux had extended to a profoundness of 150 meters ( 500 feet ) , but just over a calendar month later on March 3 , the entire lake had flipped . buoy deployed to the top and bottom of the lake were scan as the same temperature by February 28 , which is when the mixing really gets break .
Some degree of lake dollar volume happens every year , but they do n’t always achieve a full somerset . This is because the right combination of extreme air temperatures and storm are require to get the mixing happen all the way from the top to the bottom .
A full somersaulting like Lake Tahoe ’s is cause for festivity as it will help to make the good conditions for aquatic plants and animals by redistributing nutrients , aerate the piss , and keeping the bottom cool in the fount of geothermic heating . It can also be fun for human percipient , as the lake find much light after a flip intend you could see to a much cracking depth .
