The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 35 years. A second-order regression has been performed against the daily water-level elevations for the past 35 years to quantify a long-term trend in the data. The estimated first-order long-term trend in water level is 0.1329 ft/year. (Description of statistical methods)
