Is there a bottom to Lake Tahoe?

The deepest recorded depth of Lake Tahoe is 1,645 feet. To visualize this depth, imagine the bottom of Tahoe reaching down 100 feet lower than Carson City, Nevada, sitting in the basin far below Tahoe to the east. What we see as normal Lake Tahoe depth is only our perspective.

Is Lake Tahoe man-made? A. The formation of Lake Tahoe occured naturally over the course of 3-4 million years through faulting, volcanic activity, and glaciation. However, as a result of the dam (controlled by the federal water master) located in Tahoe City, the Lake is also a reservoir.

Why is the Lake so blue? Tahoe's clean air and water are the keys to the Lake's dazzling blue color.

If Lake Tahoe was completely drained, it would cover a flat area the size of California to a depth of 14 inches, but would take over 700 years to refill. Lake Tahoe is, geologically, a “young lake” having been formed 10,000 to 11,000 years ago.

Because of that 2 million year old routing, a very very deep lake was created in the basin. Lake Tahoe is 1,645 feet deep (compared to a height of 1,454 for the Empire State Building). The depth means that, despite the chill, the lake never completely freezes.

Lake Superior is the Cleanest and Clearest Great Lake Because 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.

Allegedly it's a 60-foot-long serpentine “monster” named Tessie. Tahoe Tessie that is. This isn't a new story either. The local Indian tribes have long spoken of monsters in the lake and some other theories point to a giant sturgeon perhaps inhabiting the dark areas of the water.

Compared to other lakes, Tahoe's cast of aquatic characters is fairly small. Among those you can see with the naked eye, there are several species of trout (rainbow, brook, brown and lake), the Kokanee salmon, crayfish, mysis shrimp, and a few other near-shore and bottom-dwelling fish.

Lake Tahoe, with its massive 744,600-acre foot storage capacity, should come very close to filling. (The top 6.1 ft. of storage above the lake's rim is used to provide river flows and drought reserves). This is a remarkable rebound for the lake which, in early December, was almost six inches below its natural rim.
