Drought easing in the south

June 9, 1033 am EDT

Current Streamflows
Ohio streamflows run mostly normal Sunday, the number of stations reporting much above normal is down to four remaining statewide, these are all showing up in the Scioto River basin of central Ohio. The highest flow level Sunday is 96th percentil recorded on Scioto River upper channel near Prospect, with 94th and 95th percentile flows just downstream near Dublin and Columbus. The lowest flow in OH is 5th percentile on Cuyahoga River near Newburgh Heights. As of this report, there are no active floods and no 99th percentile flows or 1st percentile extreme low flows in the network. The higher streamflows yesterday pushed back the moderate drought rating on Ohio River minor tributary Raccoon-Symmes watershed overnight. As of this report, four watersheds are rated below normal, Raccoon-Symmes and adjacent Shade River watershed, Guernsey County Wills Creek watershed and Grand River watershed in the Lake Erie basin.

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors

Seventy flood events are recorded on the USGS network Sunday, up from fifty-four yesterday. WT USA is tracking twelve of these reference flood events through our coverage area in New York, Ohio, Georgia and Louisiana. At the writing of this report, all active flood sites are located in Louisiana.

Watershed Region 7 east border Pearl River is flooding near Bogalusa, currently recorded between eight and nine inches above the channel. Region 1 in the northwest continues flooding in the same pattern as reported yesterday, Caddo Lake and Bayou Bodcau Lake are still out of their basins near Mooringsport and Shreveport, respectively. Bayou Dorcheat overruns the channel near Springhill and downstream Minden. Region 2 Little River is flooding near Rochelle. Region 4 west border river Sabine floods near Logansport, Burkeville, Bon Wier and Ruliff. The east side of Region 4 watershed Calcasieu River is flooding near Glenmora and Oberlin. Twelvemile Bayou is still running above 99th percentile near Dixie with no flood stage to reference. Sabine River is above 99th percentile at Toledo Bend Reservoir near Burkeville with no flood stage documented. For more information on the flood trend in Louisiana, see black tags indicating flood flow volume and gauge height, blue tags for 99th percentile flows, updated daily here.

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.
