Each value is the stage forecast for the Wednesday of that week. These forecasts are based on observed runoff and only include the next 24 hours of forecast precipitation. Any additional precipitation could cause an increase in river stage.

During extreme cold periods ice can form over rivers and on structures upstream causing river levels to drop lower than projected. Stay tuned to the latest hydrologic statements for the latest information.
