Lake levels have been measured for the past 50 years at Cagles Mill Lake. The highest annual lake levels (in feet, mean sea level) on record are 887.5, 887.3, 886.5, 886.0, 885.9. The other 45 annual peaks are smaller. What is the probability of having a lake level equal to or higher that 887.3 next year? What is the hydrologic risk of this occurring in the next 10 years?
