• USGS has scheduled planned maintenance to our IT infrastructure, starting Tuesday, June 28, 2022, from 7:00-9:00am Eastern Daylight Time (EDT). During the maintenance period, there will be a short interruption in the availability of the most recent time-series data. Any backlog will be made available following conclusion of the scheduled maintenance.

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.
