TranscriptionSegment A112: Tahoe Fun Facts Air Date: April 12, 2005 Tease @ 23:42 "Did you know if you poured all the water out of Lake Tahoe over the state of California it would cover the state to a depth of 14 inches?? I'm Shelly Purdy, I'll have all the details on that and other quirky facts about Lake Tahoe coming up on the Lake Tahoe Report." Anchor Intro: Lake Tahoe is one of the deepest and largest fresh water lakes in the world. Most people think of Tahoe as a recreationalists paradise. In tonight's Lake Tahoe Report, Shelly Purdy takes a look at some interesting facts about Tahoe that you probably didn't know. ((TAKE PKG)) ((track 1)) Lake Tahoe is very deep and contains an astounding amount of water. In fact, if you took all the water out of Lake Tahoe and poured it over the entire state of California, you would cover the golden state to a depth of 14 inches. And after dumping all that water out…it would take six to seven hundred years to fill back up. ((sot @ 3:46 Bob Richards, U.C. Davis)) "It's a very unique lake in many ways. It's huge and very deep. It ranks about 11th in the world when you consider its volume and depth. It's 1636 feet to the deepest point. That puts it more than 90 feet below Carson City, Nevada." ((track 2)) And aside from its astounding depth, Tahoe is also very cold. If you've ever spent some time in Tahoe's water you know just how cold it can be. ((sot @ 6:08)) "Tahoe is consistently cold below about four to five hundred feet. From there to the 1600 foot level it doesn't vary more than a couple of degreed year round. The bottom of the lake is about 39 degrees farenheight. The surface can get warm and it's nice swimming for maybe about 1-2 weeks in the summer when the temperature gets up to 70 degrees or so." ((Track 3)) Despite the cold temperature, there is a lot of life in Tahoe…especially at the microscopic level. There are more than 100 species of algae, 6 to 7 different kinds of plankton and as many as 15 different types of fish have been introduced to the lake over the years. But Tahoe remains what's called a low fertility lake. That's why the water is so crisp and clear. The challenge now is keeping it that way. With the Lake Tahoe Environmental Education Coalition, I'm shelly Purdy for KOLO News Channel 8. Anchor Tag: Lake Tahoe was formed by earthquake faulting and glaciation. And, the bottom of the lake is filled with sediment. Scientists believe there is as much as 2-thousand feet of sediment piled up at the bottom of Lake Tahoe.
