HAPPENING NOW
Delaware River watershed, Long Island streams flowing much above normal
Moderate drought in southwest NYS
Water news for Friday, March 29, 2024 1155 am
Flood Tracker provisional data from USGS streamflow monitors
Thirty-seven streamflow gauges record flooding in the USA Friday, up from twenty-five yesterday. WT tracks the nation's most common natural disaster in New York, Ohio, Georgia and Louisiana. As of this report, twelve monitors in the four states above mentioned indicate active flooding.
For New York, east state streamflows run normal to much above normal, the highest flows occurring now in the Delaware River watershed and Long Island creeks and streams. Quite the opposite, the west interior and counties bordering Lake Erie and Lake Ontario are below normal to much below normal, with moderate hydrologic drought on Alleghany River watershed in the southwest and a larger area of west interior Finger Lakes region rated below normal on the drought map Friday.
In Louisiana, Pearl River, the east state border continues to overflow near Bogalusa in Washington Parish and at the Town of Pearl River in St. Tammany Parish. In northwest LA, Bayou Dorcheat is still flooding near Springhill and Bayou Bodcau is still six and a half feet above flood stage near Shreveport. On the west LA border, the Sabine River runs three inches over flood stage near the Ruliff, TX monitoring station maintained by the Texas-Oklahoma Water Science Center.
Georgia, Day 23: Gulf of Mexico basin has an active flood going on today for the first time since Flint River flooding ended at Bainbridge on March 18. This is the first we have heard from Ochlockonee River, flooding just after 9 am this morning as observed and recorded across the GA line near Concord, Florida. On the Atlantic side of the drainage divide, Alabaha River is back on the flood radar at GA 203 near Blackshear, overtaking flood stage for the second time in a week. Alabaha was late to join in the March flooding frenzy, waiting until March 23 to make a three day excursion out of the channel. That flood stopped on Tuesday this week, and back again yesterday, running and inch over flood stage at this report. Little Satilla and Satilla Rivers are actively flooding near Offerman and Atkinson, respectively. Savannah River is still more than three feet over flood stage near Cylo; Altamaha River running almost a foot over near Baxley, Altamaha tributary Ohoopee River is as high as yesterday, if not not higher, ten to eleven inches over flood stage near Reidsville.
Ohio streamflows map resembles that of New York today, below normal in the west, normal in the east. As of this report there is no active flooding or high flows.
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.
Drinking Water Matters
The City of Watervliet came under Boil Water Advisory Monday for reasons not disclosed. The advisory applies until further notice. More to follow.
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.
