Current 90-day hydrograph at HE - 555 (263845081260701)

Graph: Continuously recorded water levels for the past 90 days are compared to the daily (maximum) water levels from last year, and to the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record prior to the current water year.. Data used to produce this graph is available via the [data used] link on the page.

One-year hydrograph at HE - 555 (263845081260701)

Graph: 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..

Long-term trend information

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, using the Seasonal Kendall Slope Estimator, is -0.0090 ft/year, measured over the last 25 years (12-JAN-2012).
