Wait, How Big Is Tahoe? 29 Years!

You've all heard the statistics about Lake Tahoe. They're on the back of restaurant menus, on calendars, in the wikipedia articles, on the travel websites. Length (22 miles), width (12 miles), depth (1635 feet), total water volume (150 cubic kilometers).

Tahoe From Space

Okay, it's a big lake. But how big is it in terms that we can understand?

Here's a statistic you've never heard.

I decided to run a few numbers. I wanted to know this: If every person on earth drank eight glasses of water a day and they dipped it out of Lake Tahoe, how long would the lake provide everyone on the planet with drinking water? A day? Several days? A few weeks?

We've got a bit over 7 billion people on this planet. That's a number too big to really grasp. Line up 7 billion 5-foot, 6-inch people and they'd stretch around the earth 291 times. Put all of us head to toe and we'd go to the moon 30 times. That's a lot of people. So if we're all drinking our recommended intake from the lake, how long would it last us?

Over 29 years.*

That's a lot of water from one mountain lake.

So the next time you drink a glass of water, invite everyone else on the planet to join you. Let's everybody do it eight times a day for 29 years.

Live large. It's Lake Tahoe.

*For those of you who want to do the math, there are a bit more than 4 eight-ounce glasses in a liter, a thousand liters in a cubic meter, a billion cubic meters in a cubic kilometer, and 150 cubic kilometers in Lake Tahoe. Divide by 7 billion people, then divide by 8 glasses a day, then divide by 365 days in a year, and you get 29 years. That's a lot of water.
