Current Streamflow provisional data from USGS streamflow gauges in Georgia
Flow volume has picked up in north and central GA overnight, much above normal streamflows are registering in the Coosa and Tallapoosa River watershed and one station on the Chattahoochee River as of Saturday afternoon. The drought map is largely unchanged overnight, lower Ocmulgee River remains at severe drought from south Laurens County, west Wheeler, east Dodge and north Telfair. Savannah and Ogeechee River watersheds remain as reported yesterday, rated below normal from Rabun to north Columbia, from Wilkes to north Screven, including Ogeechee River watershed east Washington, Hancock and Greene Counties. For the Mississippi/Gulf of Mexico side of the drainage divide, Upper Chattahoochee, Upper Flint, Coosa, Tallapoosa and Tennessee Rivers watersheds remain below normal with a new area in the Flint River watershed rated below normal Saturday, from east Randolph-west Terrell, Dougherty, Calhoun and central Baker Counties.

Tobesofkee Creek continues with the low rating as measured near Macon, the gauge height measured around 1.8 ft deep between short-duration daily releases from the dam.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Eighty-four streamflow gauges record flooding in the USA Saturday, down from ninety-three Friday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, a new flood event has started in Louisiana, there are currently six active floodings on our radar, all recorded in Louisiana.
Region 4 watershed runs from the west Louisiana border with Texas starting at DeSoto Parish, draining surface area through Sabine, Vernon, Beauregard, Calcasieu and west Cameron, also including west Rapides, west Allen and northwest Jefferson Davis Parishes. This watershed has been on the national flood map for months with Sabine and Calcasieu Rivers flooding on an off since the end of January. Sabine River breached major flood stage for a brief period mid-April. Calcasieu River has breached minor flood stage five times near Glenmora since the end of January. As of this report, Calcasieu River runs a foot and nine inches over minor flood stage near Glenmora, now also flooding at downstream Kinder, since around 730 this morning. Sabine River is also recorded flooding at two stations, near Bon Wier, TX and also near Shreveport, TX. In the northwest LA, watershed Region 1, Bayou Dorcheat and Bayou Bodcau are still flooding near Springhill and Shreveport, respectively.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
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.
