CNRFC - Hydrology - Historical Graphical RVF Interface

*** IMPORTANT *** Week of June 16 - Website Data Outage - Due to a major computer upgrade the week of June 16, nearly all data on the CNRFC web site will not be updated. We anticipate the down time to be approximately 4 days. The latest deterministic hydrologic forecasts for official forecast points will continue to be available at the National Water Prediction Service during this time.

Historical Graphical River Forecast

This interface is used to display graphical verification plots comparing our graphical River Forecasts with plots of observed river gage data, from an archive dating back to January 1, 2003. The top portion of the display shows forecast vs. observed Rain + Melt (inches), while the lower portion shows a plot of forecast vs. observed stage (feet) and discharge (cfs). Forecast data are plotted in green and observed are plotted in blue. Feedback and/or suggestions to improve the interface are welcome. Contact our CNRFC Webmaster with any recommendations. Thank you.
