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?
Will Lake Travis flood?
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.
