Official flood watch over, eleven monitored sites still flooding in LA

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty-four floodings are showing active on the USA network of the USGS Waterwatch Thursday, down from one hundred and thirty-two yesterday. WT USA tracks streamflow monitors in four states, New York, Ohio, Georgia and Louisiana. As of this report, Long Island records two sites above 99th percentile flow level, Ohio has five locations in extreme high flow, one of these in action stage looking to flood. Eleven active flood sites are monitored in Louisiana.
Watershed Region 1: Bayou Bodcau Lake and Caddo Lake are flooding near Shreveport and Mooringsport, respectively. Bayou Dorcheat continues to flood near Springhill and downstream at Minden. To the south into Region 4 watershed, border river Sabine carries on flooding near Logansport, approaching moderate flood stage three and a half feet above the channel and still rising near Burkeville, two and a half feet over near Bon Wier and a foot over the channel in the lower end near Ruliff. East Region 4 Calcasieu River runs two and a half feet over near Glenmora and four inches over near Oberlin station. To the south in Region 5 watershed, Mermentau River is a hair over flood stage at Mermentau. Vermilion Bay is no longer flooding at Cypremort Point. See black tags indicating flood flow volume and gauge height, blue tags for 99th percentile flows updated daily on the map to the right.
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.
