What this means

Forecasts by the Northwest River Forecast Center. Forecasts are issued as needed during times of high water, but are not routinely available. The reference level, or vertical datum, for this gage has been updated to NAVD88. That means the stage heights will now be reported from that reference level which will give the water level as height above mean sea level. All flood stages have been changed accordingly.
