HAPPENING NOW
Much above normal streamflows north and central GA
Ocmulgee, Oconee Rivers still flooding
Monday, January 29, 2024 - last updated 1046 pm EST
Flood and streamflow report
USGS Streamflow gauges - see Provisional Data Statement below
Oconee River breached flood stage near Penfield for the second time in a week just before 10 pm last night. As of the evening update, flow was still around the same level, five inches over flood stage. As of this update, the flow at Penfield appears to have peaked and is heading back down, slowly. We may see the flooding end Tuesday morning.
Ocmulgee River is still flooding at Macon, flow volume picked up a foot overnight, currently running well over a foot above flood stage, very little change through the day, however the trend has turned to a slow declining water level.
Streamflows through the central Atlantic drainage area remain much above normal in north and central GA shifting to seasonal normal to below normal in the south. Much the same on the Mississippi side of the divide, streamflows much above normal to high in the north and central state, shifting to normal in the south.
Alcovy River is still flowing 99th percentile above Covington, no longer in action stage and rapidly declining. Etowah River is still showing 99th percentile flow below Allatoona Dam. We don't often make note of this station as the controlled release from the dam usually stops short of flood stage. On occasion this station does flood, and has flooded recently, so it has been noted.
See black tags on the map for flood flow details, blue tags for flows above 99th percentile.
Turn around, don`t drown when encountering flooded roads. Most flood deaths occur in vehicles.

Drought Map USGS 7-day average streamflow compared with historic average
The area rated below normal on the Mississippi side of the drainage divide has shrunk Monday, the Lower Flint River watershed area from Dougherty to Decatur is back to normal, the area rated below normal extends from Marion-Schley-Macon and ends at north Dougherty.
On the Atlantic side of the divide, Lower Ocmulgee River watershed remains rated below normal at south Laurens, east Dodge, west Wheeler and north Telfair.
USGS seven-day average streamflows at each monitoring location are rated against the historic average flow volume for this day. Results appear on the drought map, showing surface area with a rating: below normal, moderate drought, severe drought or extreme drought. The drought-rated surface area most often follows watershed lines, the physical topography of drainage and direction of flow of the surface water across the state. The watershed layer on the map shows surface area impacted by streamflows in each drainage area. Turn the directional arrows on to see which way the water flows, along with hazardous spills reported in the area that could have an impact on water quality.
HABs update from Georgia Department of Natural Resources - Coastal Resources Division Shellfish and Water Quality Unit
Permanent advisories remain in effect for bacterial contamination at Jekyll Clam Creek Beach on the north end of Jekyll Island and St Andrews Beach on the south end. Lab tests processed at Brunswick on samples collected Tuesday January 2, 2024 show the enterococcus levels below the health advisory threshold. Clam Creek Beach came in at 4 cfu per 100 ml and 9 cfu per 100 ml for St Andrews.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
