Current Streamflows, Drought Map from the USGS network in Ohio
Seasonal normal streamflows predominate the landscape Friday with the highest flows occuring through the Scioto basin, four stations on Scioto tributaries Olentangy River, Alum Creek and Deer Creek flow much above normal. Another instance of much above normal flow is recorded in the Muskingum River basin on the Hocking River at Athens. Lake Erie basin streamflows are recorded at mostly normal levels Friday with two stations registering much below normal, one on the Auglaize River near Defiance and the Cuyahoga River near Newburgh Heights. Six stations record below normal flows in Ohio, one in the lower Great Miami Basin, one in Scioto, two in Muskingum basin, one in the Ohio River minor tributaries and two in the northeast Lake Erie basin. There are no extreme high or low flows, and no active flooding recorded on the Ohio network of streamflow gauges.
The Ohio drought map remains clear, no part of the state's 32 watersheds are rated below normal or any degree of drought.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Seventy-six streamflow gauges record flooding in the USA Friday, up from sixty-six 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, seventeen sites record flooding on the network, four in Georgia, thirteen in Louisiana.
Gulf of Mexico basin is experiencing another monitored flood event in south Georgia/north Florida. Ochlockonee River has breached flood stage near Concord, FL as of late afternoon yesterday, presently recorded three to four inches above flood stage. Suwannee tributary Withlacoochee River continues to flood at Skipper Bridge Rd near Bemiss, GA. On the Atlantic side of the divide, Satilla River continues to overflow at GA158 near Waycross, five inches over flood stage on a level trajectory. Savannah River flooding is ongoing near Cylo, also five inches over the channel on a steady rising trend. See black tags for flood flow details, blue tags for 99th percentile high flows on the map to the right. See black tags indicating flow volume and gauge height, blue tags for 99th percentile flows updated daily here.
Louisiana is experiencing widespread flooding this week. The view from the USGS monitored sites includes the same twelve sites reported yesterday with the addition of Bayou des Cannes, flood stage breached near Eunice around 5 am this morning in watershed Region 5. Watershed Region 1 Bayou Bodcau is down another three inches, running three feet, seven inches out of the basin near Shreveport. In Region 2, Little River runs close to two feet above the channel near Rochelle, starting to level out. To the south in Region 2, Big Creek is flowing 99th percentile near Pollock. In the southwest, watershed Region 4, Sabine River continues to flood as monitored near Burkeville, Bon Wier and Ruliff stations. Calcasieu River is flooding near Glenmora, Oberlin and Kinder. Tributary Ouiska Chitto is flooding near Oberlin in Region 4. In the east, Pearl River is flooding near Bogalusa and Town of Pearl River, along with tributary Bogue Chitto flooding near Bush.

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.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty-six streamflow gauges record flooding in the USA Thursday, down from sixty-seven earlier today. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, fifteen sites record flooding on the network, three in Georgia, twelve in Louisiana.
Georgia river flooding in the south is up to three sites overnight, Suwannee tributary Withlacoochee River is starting to recede Thursday, still flowing more than a foot and a half above flood stage at Skipper Bridge Rd near Bemiss in the Gulf of Mexico basin. On the Atlantic side of the divide, Satilla River is flooding at GA158 near Waycross, flood stage breached early yesterday evening, currently running five inches over flood stage and rising slowly. Savannah River is flooding near Cylo, flood stage breached around 3 am this morning, presently recorded less than an inch over the channel. See black tags for flood flow details, blue tags for 99th percentile high flows on the map to the right.

Louisiana flooding increased from eight to ten locations yesterday with three new locations flooding since our last update. In the east, Region 7 watershed Pearl River set to flooding near Bogalusa around 8 am yesterday morning, this flooding extends downstream to the Town of Pearl River as of around the 9pm hour last night. Pearl River tributary Bogue Chitto breached flood stage this morning around 230 am near Bush. Watershed Region 4 Calcasieu River continues to flood in the upper channel near Glenmora and mid-channel Oberlin. Flood stage was breached yesterday afternoon downstream near Kinder, currently running extends further downstream to the monitor near Kinder, currently running a foot and nine inches over, this flow appears to have peaked in minor flood stage, presently on a slow declining curve. In watershed Region 4, Sabine River flooding is recorded near Burkeville, near Bon Wier, and downstream near Ruliff, TX. Bayou Anococo flooding ended around 4 am this morning near Rosepine. Watershed Region 1 Bayou Bodcau continues a slow decline, down a few inches overnight near Shreveport, currently registering just under four feet out of the channel. In Region 2, Little River floods on near Rochelle, still rising. See black tags indicating flow volume and gauge height, blue tags for 99th percentile flows updated daily here.
