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.
