Flooding continues in Regions 1 and 4<
Extreme drought for Tangipahoa Parish
Water news for Friday, May 10, 2024 1021 am CDT
Current streamflow trends provisional data from the network of USGS streamflow monitors in Louisiana
Extreme drought persists in Tangipahoa Parish heading into the weekend with adjacent area of the Region 7 watershed to the west rated below normal. Two stations record flow values at the 1st percentile Friday, Tangipahoa River continues to run low at Robert, and Amite River is also running an extreme low level at Darlington. Natalbany River is much below normal at Baptist and other flows in the region are rated below normal. The west side of Louisiana runs above normal to much above normal and high flow values Friday, including the five stations on the west side of the state that are actively flooding in Regions 1 and 4.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Eighty streamflow gauges record flooding in the USA Friday, down from eighty-eight Thursday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, nine sites record flooding on the network, four in Georgia, five in Louisiana.
Louisiana has five stations recording flood flows Friday morning. Region 4 watershed Sabine River continues to flow two to three feet out of the channel near Bon Wier, TX and Ruliff, TX. Calcasieu River runs a foot and four inches above flood stage near Glenmora. Region 1 watershed, Bayou Dorcheat appears to have peaked and leveled off, provisionally measured a foot and nine inches out of the channel near Springhill. Bayou Bodcau has dropped down to just north of five feet over the channel near Shreveport. See black tags on the map to the right.
North and central Georgia are experiencing widespread rainfall this morning as flooding shifts through the northwest. Lookout Creek is still a foot and three inches over flood stage near New England on a sharp downward flow trend in the Tennessee River watershed. In the Coosa River watershed, Conasauga River breached flood stage around 545 pm yesterday, presently recorded flowing a foot over the channel at Tilton. Coahulla Creek is still recorded at a foot and three inches over flood stage near Dalton. Oostanula River breached flood stage at Calhoun, running half a foot over at this report. Holly Creek is no longer flooding near Chatsworth, Talking Rock Creek stopped flooding near Hinton, Fausett Creek is no longer flooding near Talking Rock and the Coosawattee and Cartecay Rivers flooding ended before noon yesterday near Ellijay. See the black tags for flood volume updated daily here as the storms roll through.
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.
