Flood Tracker provisional data from USGS streamflow monitors
Twenty-three streamflow gauges record flow above flood stage in continental USA Wednesday morning, down from thirty-five yesterday. WT tracks eight of these locations, four in Georgia and four in Louisiana.
Today is Day 21 of the March 2024 Georgia floods. Savannah River is no longer overflowing at Burtons Ferry Road near Millhaven, receding below minor flood stage around 1130 pm last night. Altamaha River is still overflowing near Baxley, the last of four Altamaha monitoring stations recording flooding over the last weeks. Savannah River still floods near Cylo, Ohoopee River is running six inches over flood stage near Reidsville and Little Satilla about the same, half a foot over flood stage near Offerman. Satilla River flowed out of the channel at GA158 near Waycross the first part of this week. That flooding ending this morning around 230 am.

Hudson River ran over briefly yesterday at Piermont while Great South Bay was above flood stage at Lindenhurst and West Sayville. As of Wednesday, no flooding is recorded at any monitored location in the NYS USGS network.
Louisiana has one less flood location to report overnight as Pearl River calmed down into its channel near Bogalusa around 2 am this morning. As of this update, Louisiana east border Pearl River is still flooding at the Town of Pearl River in St. Tammany Parish. In northwest LA, Bayou Dorcheat is still flooding near Springhill, Bayou Bodcau still flooding near Shreveport. On the west LA border, Sabine River is still overflowing in the south near Ruliff TX.
East Ohio streamflows are up much above normal to high with one 99th percentile flow recorded on Little Muskingum River near Bloomfield, a tributary of the Ohio River. More to follow.
Hazardous Spills
Heavy rain events in Dekalb County often come with an especially nasty side effect. Callers to Georgia EPD report overflowing manholes and raw sewage escaping into the creeks on both sides of the state divide, north Dekalb creeks heading for the Chattahoochee River system in the Gulf of Mexico basin, or south Dekalb, directing runoff and spilled contaminants to the Ocmulgee River of the Atlantic drainage basin. During the heavy rains of March, more than 750 thousand gallons of raw sewage is reported to have overflowed from manholes into the watersheds. In 2022, WTGA reported 10 million gallons of sewage impacted the creeks flowing into Lake Jackson, the head of the Ocmulgee River. Dekalb County has a strategy to reduce these stormwater overflows, WTGA investigates. More to follow.
Drinking Water Advisories
Grand Oaks, St Simons Island is under BWA following repairs to a water line. The advisory will apply for 18-24 hours after service is restored.
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.
