Current Streamflows, Drought Map from the USGS network in Ohio
Streamflows run overwhelmingly normal statewide Wednesday, just three stations in the Ohio network recording below normal flows. One station in the Muskingum basin is recorded much above normal, the Wakatomika Creek near Frazeysburg in Muskingum County runs 92 percentile. Also in the Muskingum basin, Salt Creek near Chandlersville continues to record a water level and volume much below normal, yesterday recorded fifth percentile, today even lower, 4th percentile. Lake Erie basin runs entirely seasonal normal from east to west.
No change to the drought map overnight. Muskingum River basin's Wills Creek watershed remains below normal, along with Grand River watershed, also below normal.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty-seven streamflow gauges record flooding in the USA Wednesday mid-morning, up from sixty-six 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, eleven sites record flooding on the network, one in Georgia, ten in Louisiana.
Louisiana flooding increased from six to eight locations yesterday, and increased again this morning from eight up to ten floodings on the USGS network of streamflow gauges. In Region 2, Little River broke out of the channel near Rochelle around 830 am, on a steady upward trend. Pearl River breached flood stage near Bogalusa a bit earlier, around 8 am this morning in Region 7. Pearl River is currently running on an upward flow trend. In watershed Region 4, Sabine River flooding has expanded upstream near Burkeville, breaching flood stage 36 ft yesterday afternoon. Flow here looks to have peaked in minor flood stage and may start to slow down this afternoon. Sabine continues to flow more than four feet out of the channel downstream near Bon Wier, well into moderate flood stage downstream near Ruliff on a steep rising trend. Bayou Anococo flooding has peaked and slowly receding near Rosepine. Calcasieu River is flooding near Glenmora, just under the two foot above flood stage mark on a receding trend. Downstream near Oberlin, Calcasieu has peaked in moderate flood stage, just short of three and a half feet out of the channel and slowly receding. Bundick Creek continues to run high near DeRidder. In Region 7, the Tchefuncte River is no longer running 99th percentile flow near Folsom. Watershed Region 1 Bayou Bodcau came down a few inches overnight near Shreveport, currently registering four feet one inch out of the channel. See black tags for flood flow details, blue tags for 99th percentile high flows here.
Georgia sparked up a new flood incident overnight in the deep south. Gulf of Mexico basin's Suwannee River watershed is registering a flow two feet above flood stage on the Withlacoochee River at Skipper Bridge Rd near Bemiss as of early evening yesterday. NWS forecasts more isolated thunderstorms through north and central Georgia today and through the rest of this week, possibly including the weekend. See black tags on the map indicating the level of flooding 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.
