NOTE: River forecasts for this location take into account past and future precipitation. The stages/flows that will occur may be different if future rainfall is different than forecast.

NOTE: Gage observations from this river gage have been temporarily discontinued due to a system maintenance and replacement project. River forecasts will continue but will not have the benefit of using the actual river flows.
