Streamflow outlook

NOAA National Water Model forecast, issued 15 hours ago. The NWM models discharge for every river reach in the country, including the many gauges the National Weather Service does not forecast individually. It is a model, not an official NWS river forecast, and it predicts flow rather than water level.

No National Weather Service flood stage is published for this gauge, so no flood category can be shown — why some gauges have no flood stage.
