Station Notes
gage
Gage height datum conversion to the NAVD88 datum for this streamgage was completed on May 9, 2018. All reported gage heights and those associated with discharge measurements and stage-discharge ratings have been converted and are consistent with elevations based on the NAVD88 datum. A conversion factor of 24.48 ft was used to convert the old gage heights to the currently reported instantaneous gage height, discharge measurement gage heights, and stage-discharge rating points.
