Current 30-day hydrograph at L - 581 (263532081592201)

Graph: 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 this graph is available via the [data used] link on the page.

Long-term trend information

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)
