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.

Description of information presented in the current 30-day hydrograph at P-49 (274812081190301)
The change in daily water-level elevations has not been mathematically correlated to time for the period of record based on operational considerations. Instead of a long-term trend line, the data are, therefore, compared to the zero-slope (flat, linear) regression curve for the existing period of record daily water-level elevations. This approximates, but may not equal, the period of record mean. (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.

Long-term water-level elevation trends are estimated by statistical analysis, then water-level elevations for the past year are compared to the duration information, compensated for long-term trends, for the corresponding weeks of the year.
