WT Flood tracker - Louisiana storms spike river flooding
Chance of thunderstorms for west interior
Water news for Tuesday, May 14, 2024 updated 1150 am EDT
Current Streamflows, Drought Map from the USGS network in New York
A chance of showers and thunderstorms today and overnight may relieve the below seasonal normal streamflow trend through the west this week.
Northeast NYS flows remain below normal through the Black River, Lake Ontario east and St. Lawrence River watersheds, increasing to normal at the Lake Champlain watershed. Central basin flows run normal to below normal with the lowest rating occurring in the Schoharie Creek sub-region of the Mohawk River watershed. Upper Hudson records two sites below seasonal normal today, up from one yesterday. Mohawk River is rated below normal near the confluence with Hudson River with normal ratings the rest of the way down to Long Island Sound. Long Island flows run normal to above normal again today.
Streamflows in the west interior are trending slightly lower Tuesday with more stations appearing below normal in the Susquehanna and Allegheny River watersheds. Genesee River is still predominantly below normal with Lake Ontario minor tributaries west, Niagara River-Lake Erie and Allegheny showing a mix of below normal and normal. Southeast flowing watersheds Chemung, Susquehanna, Delaware and Ramapo run mostly normal with one or two stations at below normal.
Parts of the St. Lawrence and Black River watersheds remain on the drought map as an area in north Essex County in Lake Champlain watershed finds a below normal rating Tuesday. A portion of the Upper Hudson River watershed comprised of southwest Essex, central Hamilton and central Warren Counties remains below normal. In the west interior, the Lake Ontario minor tributaries west section is back on the drought board at below normal. Lower Genesee remains at below normal while the Allegheny River is cleared and no longer rated. A band of Niagara River - Lake Erie watershed running along Lake Erie shoreline in Chautauqua County extends along the north edge of Chautauqua County. The Schoharie Creek channel and feeder creeks coming off the west slopes of the Catskills remains below normal.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty-four streamflow gauges record flooding in the USA Tuesday morning, up from sixty-two 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, six sites record flooding on the network, all in Louisiana.
Louisiana flooding has shifted overnight with water levels down in the northwest and three new locations recording flood in west central and southwest. Bayou Dorcheat flooding ended around 11 pm last night near Springhill in watershed Region 1 while Bayou Bodcau continued its slow decline near Shreveport, currently registering a level four feet four inches above the basin. To the south in watershed Region 4, Bayou Anococo overran its channel near Rosepine around 1130 am yesterday, currently flowing more than two feet over minor flood stage and rising. Sabine River is up overnight, running three feet nine inches over the channel near Bon Wier and almost two feet over near Ruliff, TX. Calcasieu River flooding spiked yesterday as well, running two-plus feet over near Glenmora and three feet over near downstream Oberlin. Three gauges record 99th percentile flows by mid-morning Tuesday, Bayou San Patricio has slowed down near Benson in Region 1 below the 99th percentile. Still flowing high are Big Creek in Region 2 near Pollock, Bundick Creek is running high near DeRidder. Sabine River runs in action stage, up three inches in three hours, now three inches from flooding near Burkeville.

NWS is calling for scattered showers today for central Georgia with the risk of a tornado, damaging winds and hail. As of this report, there are no active floods or extreme high flows registering on the USGS network of streamflow monitors in Georgia. Coosawattee River is no longer flowing at the 99th percentile near Carters.
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.
