gage
Gage height datum conversion to the NAVD88 datum for this streamgage was completed on May 8, 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 304.90 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.
