Description of information presented in the current 30-day hydrograph at H-11A (272504081120101)
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)
