Will Lake Travis flood?

Question

Lake Travis at 679.6 ft above sea level is 99% full.  It is expected to rise between 682 and 685 ft. will Lake Travis flood if it reaches 685 ft?

Answer 1

We need to find the maximum height of Lake Travis to determine if it will flood at 685 feet or not.

If it is 99% full at 679.6 feet, then 679.6 is 99% of the maximum height, and we can set up an equation to find the maximum height, x, as follows:

679.6 = .99x

To get x by itself, divide both sides by .99.  This gives:

686.46 = x

Since the maximum height is 686.46 feet, Lake Travis will not flood if it rises to 685 feet.
