Subject: Upgrading River Forecast Services from Flood-only to Daily 

Issuance for Selected Locations in East Central Georgia and Central 

South Carolina



Effective June 1, 2026, the National Weather Service (NWS) Columbia 

office in coordination with the Southeast River Forecast Center 

(SERFC) will upgrade hydrologic services for 3 river gauge 

locations. Services will transition from “flood-only” forecasts to 

daily routine forecasts. 



Previously, these locations were designated as flood-only forecast 

points, meaning the five-day forecast was only provided by SERFC 

hydrologists when river levels were expected to rise near or above 

Minor Flood Stage. Following inquiries from partners and users, the 

SERFC will now provide daily, year-round forecast information for 

these sites.



This transition provides several benefits: Enhanced Situational 

Awareness: Provides valuable data during drought and/or low flow 

conditions, not just flood events.

Recreational Safety: Supports enhanced services for recreational 

interests and public safety along river reaches.

Consistency: Daily modeling of points situated between or above 

existing daily forecast locations ensures a more seamless hydrologic 

profile across the area.



The enhanced forecasts will be integrated into the existing SERFC 

workflow and distributed through the local NWS office to the online 

National Water Prediction Service (water.noaa.gov). Note: Not all 

SERFC forecast points will transition to a daily forecast frequency. 

In some cases, a river gauge location will remain "flood-only" due 

to hydropower releases, low-flow modeling complexities, or instances 

where forecasts are generated locally by the NWS Columbia office 

rather than the SERFC.



The following gauges will transition to daily issuance. Sites are 

listed by forecast grouping, name, NWS ID, and USGS ID.
