*** 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.

!!! IMPORTANT !!! Flood Threshold Terminology Changes - On October 29, the CNRFC updated flood threshold terminology and corresponding colors to align with the National Weather Service (NWS) standards across the country. The new terminology and colors were implemented on all CNRFC webpages, including the front map interface and individual river forecast points. More information can be found here.
