D
Continuously recorded water levels for the past 30 days are compared to daily (maximum) water levels from last year, the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record, and daily levels for the 2001 drought year.
Data used to produce the current 30-day hydrograph at SW DRIVE (282434081283102)
Description of information presented in the current 30-day hydrograph at SW DRIVE (282434081283102)
The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 35 years of record. A linear regression has been performed against the daily maximum water-level elevations for the past 35 years to quantify a long-term trend in the data. The estimated long-term trend in water level is -0.176 ft/year. (Description of statistical methods)

Continuously recorded water levels for the past 90 days are compared to daily (maximum) water levels from last year, the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record, and daily levels for the 2001 drought year.
