NOTE: During winter months, stage and discharge may be significantly affected by backwater from ice, resulting in incorrect discharge data. Consequently, discharge data may not be displayed during periods of ice effect. Click here for more information.

The statistics generated from this site are based on approved daily-mean data and may not match those published by the USGS in official publications. The user is responsible for assessment and use of statistics from this site. For more details on why the statistics may not match, click here.
