*** 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.
On June 20, 2023, the datum was changed from USED to NAVD88 (+2.46 feet). As a result the monitor stage was updated to 38.5 ft and flood stage was updated to 44.5 ft.
