Current streamflow situation provisional data from USGS streamflow monitors in Ohio
Normal to above seasonal normal streamflows continue Tuesday with a run of much above normal flows recorded in south-central Paint Creek and Brush-Whiteoak watersheds. The Scioto River basin is entirely clear of the drought map Tuesday. Little Miami River watershed remains on the drought map rated below normal, the last area of Great Miami River basin remaining on the drought map. In the Muskingum River basin, Licking River watershed is rated below normal, Will Creek watershed remains at severe drought rating. Shade River and Little Beaver Creek watersheds have cleared off the drought map overnight, leaving only Raccoon-Symmes of the Ohio River minor tributaries. In the Lake Erie basin, the Black-Rocky, Cuyahoga and Grand River watersheds remain below normal.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Seventy-three streamflow gauges record flooding in the USA Tuesday, down from seventy-eight Monday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, we are watching seven active flooding events recorded on the network, all in Louisiana.
Louisiana watershed Region 1 flooding in the northwest involves the Bayou Dorcheat, running ten inches over flood stage near Springhill in Webster Parish. Bayou Bodcau continues to flood six feet four inches over the basin near Shreveport in Bossier Parish. Region 4 watershed Sabine River continues to flood from the mid-channel station near Burkeville. Flooding is recorded on Sabine River downstream near Bon Wier, TX and further downstream near Ruliff, TX. To the east in watershed Region 4, Calcasieu River continues to flood a foot and nine inches over near Glenmora with the flow level downstream near Kinder just a fraction of an inch above flood stage, this flooding likely ended during this report, more to follow.
Harmful Algal Bloom (HAB) Monitoring based on satellite images from National Centers for Coastal Ocean Science (NCCOS)
The latest image obtained from NCCOS for west basin Lake Erie was captured May 5 at a surface wind speed of 10.7 mph. The image is completely cloud obscured along the shorelines with no sign of HAB activity in the visible open water in this image. Click here for more information on Lake Erie HABs spotted in April.
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.
