WT USA Flood Tracker - 4 events in Louisiana
Lake Champlain watershed enters moderate drought
Water news for Wednesday, May 1, 2024 936 am EDT
New York State drought map has shifted overnight with moderate hydrologic drought expanding eastward across the north, from the Black River watershed into the Lake Champlain watershed in parts of Hamilton, Warren and Essex. The current streamflow situation includes above normal flow values through the Mohawk River channel Montgomery County and Upper Hudson River watershed Saratoga and Albany Counties. Below normal streamflows occur through all drainage basins with a few much below seasonal normal values showing up in the Black River, St Lawrence and Delaware River watersheds.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Seventy-five streamflow gauges record flooding in the USA Wednesday, down from ninety on Tuesday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report we are reporting on 4 active floods, all in Louisiana.
New Orleans is under dense fog advisory again this morning with one less flood monitored in the west since our last report. Sabine River is no longer flooding near Bon Wier, TX tucking back inside the channel around 230 am this morning. Sabine River still runs a foot and a half over flood stage downstream near Ruliff, TX. Calcasieu River is up again overnight near Glenmora, presently running a foot and three inches over flood stage. Flow appears to have peaked and starting to decline. Bayou Anococo continues to flood near Rosepine, running a foot and three inches over flood stage and beginning to decline. Bundick Creek stopped rising just short of flood stage, still recorded Wednesday morning in 99th percentile flow on a steady decline trend near DeRidder. North in Region 1 Bayou Bodcau is remains on a gradual declining flow trend near Shreveport, down three inches overnight, currently running eight feet three inches over flood stage. Bayou San Patricio is no longer in a 99th percentile flow near Benson.
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.
