Web Portal Changes: The Advanced Hydrologic Prediction Service (AHPS) hosted at https://water.weather.gov will be replaced by the National Water Prediction Service (NWPS), with a target of Spring 2024. Existing AHPS content and features will be preserved and expanded within NWPS. The NWS is now accepting feedback on NWPS. Please visit https://www.weather.gov/owp/operations for more information.

Experimental National Water Center Products: Flood Inundation Mapping services are now available for 10% of the U.S. population. Please visit https://www.weather.gov/owp/operations for more information. The National Hydrologic Discussion, Area Hydrologic Discussion, Flood Hazard Outlook, and real-time geospatial services depicting River Forecast Center and National Water Model forecasts, continue to be accessible via the URL above, as described in the StoryMap here.

Possible reasons: There are no FEMA National Flood Hazard Layers for the location which you are viewing on ESRI Maps. The FEMA Web Mapping Service (WMS) is down. Note: Your zoom level may have changed. ESRI's zoom levels must be between 14 and 16 to show National Flood Hazard layers.

22	Widespread moderate flooding continues to expand further into the woodlands...pasture and fields near the river...upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road. The bridge forms an obstacle and acts like a dam causing some backwater and erosion eddies to the sides of the bridge. County officials will close the bridge to the public.
20	Moderate flooding begins. Widespread flooding expands further into the woodlands...pasture and fields near the river...upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road. The water reaches the bottom of the bridge which begins to form an obstacle and act like a dam causing some backwater and erosion eddies to the sides of the bridge. County officials may close or restrict access to the bridge.
18	Widespread minor flooding expands further into the woodlands...pasture and fields along the river...upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road. Many locations near the river channel will be under several feet of water.
16	Minor flooding expands further into the woodlands...pasture and fields along the river...upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road.
14	Minor flooding continues to expand into the woodlands...pasture and fields along the river...upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road.
12	Minor flooding of woodlands...pasture and fields begins along the river...upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road.
10	Bankfull and Action Stage is reached along the river upstream and downstream from the gage on Georgia Highway 286 or Dawnville Road.

1360 cfs	Recommended flow level necessary for a "good" paddling run of the 10.8 mi stretch of the Conasauga River from Old Georgia Highway 2 Bridge to US Highway 411.
4731 cfs	Recommended flow level necessary for a "fast and comfortable" paddling run of the 10.8 mi stretch of the Conasauga River from Old Georgia Highway 2 Bridge to US Highway 411. This gauge is 24 miles downstream but can be used as a proxy for this section of the river which is the most visited section of the Conasauga River by boaters, campers and anglers.
800 cfs	Minimum flow level recommended for paddling the 10.8 mi stretch of the Conasauga River from Old Georgia Highway 2 Bridge to US Highway 411. The river will be rocky but passable.
