Streamflow Situation provisional data from USGS current streamflow monitors
Below normal streamflows persist in northwest Georgia Thursday with normal ratings in the northeast. Central Georgia shows up an even mix of normal and below normal ratings on both sides of the state divide. In the south, three rivers are flooding as recorded on seven streamflow monitors.
Ogeechee River reclined back into its channel near Eden around 7 am this morning, ending the flooding on this Savannah River tributary. Altamaha River is shows signs of slowing down today, volume is down over 10000 cfs and the water level is down half a foot overnight according to USGS provisional data collected close to the head of Altamaha. This free flowing river is no longer being pumped up by flood water from the Oconee, Ocmulgee and Ohoopee Rivers. The last of the runoff collected from 11400 square miles of central Georgia is moving downstream to the outlet on the Atlantic coast near Brunswick. Four and a half feet out of the channel near Charlotteville and running 44 thousand cubic feet per second, Altamaha is still doing the work of a river, soaking the landscape in its flood plain. Flow measured near Baxley is down half a foot overnight, still running five feet above the channel at 54000 cubic feet per second. By the time Altamaha hits Doctortown, it is flowing a foot and inches over the channel at 60 thousand cubic feet per second. Near Everett City, the last flow monitoring station in the channel, Altamaha is a foot and a half over at 63 thousand cubic feet per second.
Savannah River is still rising at Burtons Ferry Rd, running more than a foot and a half over the channel near Millhaven. Downstream near Cylo, Savannah is almost three and a half feet out of the channel and still rising. Satilla River is still flooding at Atkinson, a bit less than two inches over and receding slowly. No extreme low flows are recorded as of this report.
Check black tags on the map for flood levels updated throughout the day, blue tags for high flow. See the Special Flood Report for March 2024, Timeline of river flood, tracking the movement of water through the channels to the outlets in the Gulf of Mexico and Atlantic Ocean.
Flooding in the USA provisional data from USGS streamflow monitors
Twenty stream gauges record flood stage in continental USA Thursday afternoon, down from twenty-one this morning.
WT is currently tracking flooding at thirteen of these locations, located in Georgia and Louisiana.
New York Water Science Center confirms that the coastal flood monitor on Reynolds Channel at Point Outlook on the east end of Long Beach Barrier Island has been malfunctioning on and off since March 15. The provisional data concerning this flood signal has been confirmed an error, there is no flooding observed in NYS at this time.
Louisiana marks another day of flooding in Regions 1, 4 and 7 Thursday. Rivers are roaming out of their courses on the east side and west side of the state again today, six monitoring stations supplying the provisional data for this report. After the spring equinox, Bayou Dorcheat is still flooding near Springhill and downstream Minden. Bayou Bodcau is overflowing near Shreveport. Pearl River is still out of the channel near Bogalusa and at the municipality of Pearl River.

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.
