WEEKEND WATER REPORT
Sunday Edition
Water news for Sunday, May 12, 2024 1011 am CDT
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Fifty-seven streamflow gauges record flooding in the USA Sunday morning, down from seventy Saturday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, five sites record flooding on the network, all in Louisiana.
Louisiana posts the same five stations running above flood stage Sunday as reported the past week. Region 4 watershed Sabine River continues to recede, down more than half a foot overnight, currently running nine inches above flood stage near Bon Wier, TX. Water level at downstream station near Ruliff, TX is also down overnight, currently running a foot and ten inches over the channel. Calcasieu River runs less than a foot above flood stage Sunday morning, on a declining trend. In Region 1, Bayou Dorcheat continues on a declining flow trend, flowing a foot and two inches above the channel near Springhill. Bayou Bodcau dropped half a foot overnight, running four and a half feet above the channel near Shreveport. See black tags on the map to the right.
Two sites flooding yesterday in northwest Georgia have subsided since the Saturday report. West Chickamauga Creek was recorded three inches over the channel at GA 146 near Lakeview at the time of the Saturday report. This monitored flood event ended around 930 am yesterday. In the Coosa River watershed, the Oostanula River receded back into the channel at Calhoun around 830 am this morning. Coosawattee River records 99th percentile flow near Pine Chapel and Carters with a level volume trend.

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.
