The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 25 years of record. A linear regression has been performed against the daily maximum water-level elevations for the past 25 years to quantify a long-term trend in the data. The estimated long-term trend in water level is -0.315 ft/year. (Description of statistical methods)
