Current 90-day hydrograph at STL- 264 (273109080270301)

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.

Long-term trend information

The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 25 years of record. A linear regression has been performed against the daily maximum water-level elevations for the past 25 years to quantify a long-term trend in the data. The estimated long-term trend in water level is -0.057 ft/year. (Description of statistical methods)
