Flood Tracker provisional data from USGS streamflow monitors
Eighty-two streamflow gauges record flooding in the USA Tuesday afternoon, down from ninety-three this morning. WT tracks the nation's most common natural disaster dynamics through New York, Ohio, Georgia and Louisiana. As of this report we are watching 28 monitors indicating active flooding: 14 in Georgia and 14 in Louisiana.
All flooding has subsided in Ohio since Tuesday morning, where three stations were recording flows above flood stage. Ohio River is no longer flooding at Point Pleasant, WV or downstream Portsmouth by Tuesday afternoon. Muskingum River basin tributary Killbuck Creek is back in its channel at Killbuck.
As of this report, New York has no active flooding, one monitor is recording 99th percentile flow on Long Island, Swan River is still flowing high at East Patchogue.
Georgia Day 41 of continuous flooding is down to 14 sites recording provisional flow data above flood stage. Altamaha flooding began March 9, three days after heavy rains in the north set the state into flood mode. The monitor near Baxley records flooding for 26 days, the Altamaha got back into the channel near Baxley on April 4. After a ten day break, Altamaha is back to flooding near Baxley with contribution from an overflowing tributary, the Ohoopee River, currently flowing a foot-plus over flood stage near Reidsville. Alabaha River is no longer flooding near Blackshear, the overflow at GA 203 got back in the channel an hour ago. Satilla River is still spilling over at two locations near Waycross and more than three feet over at Atkinson. Little Satilla is a foot and four inches over near Offerman. Savannah River runs a foot and half over near Cylo. In the Gulf of Mexico basin, Ochlockonee River was late to flood mode, missing the early March rains. The April 11 rain event landed right on top of the 1000 square mile Ochlockonee drainage basin, got to flooding at three monitored locations, presently flowing two feet out of the channel south of the border near Concord, FL. Withlacoochee River continues to breach the channel near Bemiss, Quitman and downstream near Pinetta, FL. Suwannee River tributary Alapaha River is still running 99th percentile near Alapaha and overflowing downstream Statenville and Jennings, FL. Suwannee River is flooding at US 441 near Fargo. In the Atlantic basin, Altamaha River is overflowing its banks near Baxley for the second time this year.
Fourteen stations record flooding in Louisiana Tuesday afternnoon. Region 1 Bayou Dorcheat continues to flood near Springhill and downstream at Minden. Bayou Bodcau floods near Shreveport and Caddo Lake is still flooding near Mooringsport. In watershed Region 2, Little River continues to flow more than four feet over near Rochelle. In Region 4, Sabine River is recorded as flooding near Logansport, Burkeville, Bon Wier and Ruliff. Calcasieu River continues to run over its banks as monitored near Glenmora, downstream near Oberlin and Kinder. In Region 7, Pearl River continues to flood near Bogalusa and downstream at Town of Pearl River.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.
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.
