National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.

Note: The hydrograph at the top of the page is the official NWS forecast for this location based on 48 hours of forecasted rainfall. The ensemble hydrographs shown here are used to assess the range of possible river levels and likelihood of river flooding over the next 10 days using dozens of model-derived, 10-day rainfall forecasts.
See the Product Description Document link for more information on the Meteorological Model-based Ensemble Forecasting System (MMEFS) which produces the ensemble hydrographs above.
Clicking on each ensemble hydrograph enlarges the graph and takes you to the MMEFS website for additional guidance.
