WT USA network flood update - Ohio flooding
Georgia on tornado watch overnight
Water news for Tuesday, April 2, 2024 update 1025 pm EDT
Flood Tracker provisional data from USGS streamflow monitors
Eighty-three streamflow gauges record flooding in the USA Tuesday late evening, up from seventy-three floodings at our last update. WT tracks the nation's most common natural disaster dynamics through New York, Ohio, Georgia and Louisiana. As of this report, 30 monitors indicate active flooding; 4 in Georgia, 4 in Louisiana and 22 in Ohio.
New York State streamflows dip further below normal Tuesday in an area very recently flowing much above seasonal normal. Lower Hudson and Delaware River watersheds record mostly normal flows Tuesday as Susquehanna watershed drops further below normal, with just one station still posting a normal flow level.
New to the drought map, the current streamflows in St Lawrence River watershed around the Oswegatchie River measure below normal to much below normal Tuesday, Little Salmon River flowing much below normal at Bombay sends north Franklin County to the drought map Tuesday. Moderate hydrologic drought remains on Alleghany River watershed in the southwest with Oswego River - Finger Lakes, Chemung and Genesee Rivers watersheds remaining below normal on the drought map Tuesday, watch for Susquehanna River to join the drought map shortly.
Current streamflow map for Ohio registers twenty-two stations above flood stage. Great Miami River, Mad River, Muskingum River, Scioto River, Licking River are flooding Tuesday night, see map for updated flood flows.
In Louisiana, Calcasieu River is up overnight, recorded at a foot over flood stage near Glenmora. In Region 1 northwest LA, Bayou Bodcau water level appears to be coming down, dropping several inches overnight, running five feet five inches above flood stage Shreveport. Pearl River on the east state border runs two feet over flood stage near Bogalusa in Washington Parish and a foot and three inches over at downstream Town of Pearl River in St. Tammany Parish.
Georgia, Day 27: Northwest and west GA on Tornado Watch until 3 am. On the Atlantic side of the drainage divide, Ohoopee River flooding ended near Reidsville around 530 pm today. Altamaha River is still flooding Tuesday night, around the same level as this morning, nine inches over near Baxley. Savannah River dropped down through the day, running a foot and ten inches over near Cylo. Little Satilla and Satilla Rivers are down slightly, Little Satilla five inches over near Offerman and Satilla River an even two feet over flood stage at Atkinson.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.
As many NYS 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. WTNY.us tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's 17 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.
