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.
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.
Georgia has experienced widespread flooding through the month of March, beginning with heavy rains March 6 starting the creeks and tributaries overflowing on both sides of the state drainage divide. 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.

As of this report, 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.
Streamflow Situation from USGS current streamflow monitors
Streamflow monitors show normal to above normal statewide with two ratings much below normal in the west, one high rating showing up on Long Island at Valley Stream.
No active flooding or extreme high or low flows observed as of this report.
As many NYS 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. WTNY.us tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's 17 watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
Drought Map 7-day average streamflows
Severe drought rating has been applied to Allegheny River watershed area in central Chautauqua County. Adjacent Cattaraugus County is rated below normal. Geneseee River watershed remains below normal. Oswego River - Finger Lakes watershed is off the drought map.
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.
