Water news for Wednesday, April 17, 2024 740 am EDT
Flood Tracker provisional data from USGS streamflow monitors
Thirty-one streamflow gauges record flooding in the USA Wednesday morning, down from eighty-two yesterday. WT tracks the nation's most common natural disaster dynamics through New York, Ohio, Georgia and Louisiana. As of this report we are watching 27 monitors indicating active flooding: 13 in Georgia and 14 in Louisiana.
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 and one tributary of the Upper Hudson River is reporting provisional flow data in the 99th percecntile.
All flooding has subsided in Ohio, three monitors in the central Scioto River basin record 99th percentile flows Wednesday morning, one high flow recorded on Mahoning River in the northeast Upper Ohio River basin ahead of a severe storm warning for the north. Yesterday all flooding ended on the Ohio River. More to follow as the storms land later today.
Georgia Day 42 of continuous flooding dropped another active flood site overnight. As of 4 am this morning, Withlacoochee River is no longer flooding Skipper Bridge Rd near Bemiss. Downstream, Withlachoochee is still flooding near Quitman and Pinetta, FL. Suwannee River tributary, Alapaha River is still running 99th percentile near Alapaha and overflowing downstream Statenville and Jennings, FL. Suwannee River itself continues to flood at US 441 near Fargo. Elsewhere in the Gulf of Mexico basin, Ochlockonee River still flows out of the channel south of the border near Concord, FL. In the Atlantic basin, Altamaha River is overflowing near Baxley for the second time this year. 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 got back to flooding near Baxley, along with tributary Ohoopee River, currently flooding near Reidsville. Satilla River is still spilling over at two locations near Waycross and at Atkinson. Little Satilla is over near Offerman. Savannah River runs over near Cylo.
Fourteen stations record flooding in Louisiana Wednesday, as reported on 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 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.
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.
