Current Streamflows, Drought Map from the USGS network in Ohio
Streamflows have settled back to seasonal normal levels statewide Monday with one station in the upper Scioto River watershed still showing up above the 90th percentile. A handful of below normal ratings are registering Monday, three of these are in the middle Scioto channel, two are in the Muskingum River basin, including onm much below normal rating on the Salt Creek near Chandlersville. Lake Erie basin is consistently normal across the north state. Ohio River minor tributaries flow at seasonal normal along the east and south borders.
Muskingum River basin's Wills Creek watershed holds on to a below normal rating Monday, one of two watersheds remaining on the drought map for Ohio. In the Lake Erie basin, the Grand River watershed shows up with the below normal rating. The remaining surface area of Ohio is enjoying seasonal normal flow levels, therefore, no drought.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty two streamflow gauges record flooding in the USA Monday morning, up from Fifty-seven Sunday. 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.
NWS is calling for more thunderstorm and rain activity in central state this week with potential for localized heavy rains and flooding where the ground is already saturated. As of this report, there are no active floods registering on the network. Coosawattee River records 99th percentile flow near Carters with a declining flow trend.
See blue tag on the map for 99th percentile flow volume, updated daily here.
Louisiana posts the same five stations running above flood stage again going into Monday as reported the past week. Region 4 watershed Sabine River is up overnight, running more than two feet above the channel near Bon Wier. Downstream near Ruliff, the flooding continues a foot and a half above the channel. Calcasieu River is also up, more than a foot over flood stage near Glenmora. In Region 1, Bayou Dorcheat continues on a declining flow trend, flowing nine inches over flood stage near Springhill. Bayou Bodcau has maintained a level four and a half feet above the basin near Shreveport for the last twenty four hours. See black tags on the map 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.
