HAPPENING NOW
Sabine River flooding ends overnight
Black Bay HAB persists
Water news for Saturday, March 30, 2024 946 am CDT
Harmful Algal Bloom from the satellite monitoring program of the National Centers for Coastal Ocean Science (NCCOS)
Black Bay is still glowing with a widespread HAB mass as seen from the NCCOS full color image captured March 29 at wind speed 12.9 mph. High concentration HAB matches the color scale for 700 thousand cells per 100 ml. The March 28 capture gives a clear view of all the southeast water bodies, no HAB activity is noted in Lake Pontchartrain or surrounding area lakes.
Flood Tracker provisional data from USGS streamflow monitors
Thirty-four streamflow gauges record flooding in the USA Saturday, down from thirty-seven yesterday. WT tracks the nation's most common natural disaster dynamics through New York, Ohio, Georgia and Louisiana. As of this report, eleven monitors indicate active flooding; 7 in Georgia and 4 in Louisiana.
In Louisiana, Sabine River on the west state line crawled back into its channel near Ruliff, TX last night around 10 pm, currently running two inches below flood stage and dropping. Pearl River on the east state border continues to overflow a foot and a half over near Bogalusa in Washington Parish and half a foot over flood stage at the Town of Pearl River in St. Tammany Parish. In northwest LA, Bayou Dorcheat is still four inches over near Springhill and Bayou Bodcau is down slightly overnight, a little more than six feet above flood stage near Shreveport.
Georgia, March Flood Day 24: Gulf of Mexico basin continues to record one flood location, this being south of the Georgia-Florida line. Ochlockonee River registers provisional measurement of two inches above flood stage Saturday morning near Concord, Florida. On the Atlantic side of the drainage divide, Alabaha River runs right on flood stage Saturday morning at GA 203 near Blackshear. Little Satilla and Satilla Rivers are actively flooding near Offerman and Atkinson, runnning a foot over and close to a foot and a half over flood stage, respectively. Savannah River is receding, less than three feet out of the channel near Cylo this morning. Altamaha River running more than a foot over near Baxley, with blackwater tributary Ohoopee River a foot over near Reidsville.
New York State streamflows run normal to above normal down the east side, two monitors indicate much above normal flows on Long Island and one much above normal in the Delaware River watershed, a slowing of the above seasonal normal trend. In the other direction, the west interior has gone further toward drought overnight, most streamflows much below normal, just one station reading normal flow volume west of Ithaca. Moderate hydrologic drought remains on Alleghany River watershed in the southwest, Chemung River watershed joins the drought map at below normal. Genesee River watershed records much below normal volume from the top to the outlet at Rochester. Finger Lakes region remains below normal on the drought map Saturday.
Ohio's current streamflow map resembles New York streamflows again, below normal to much below normal with one extreme low flow in the west and central state, primarily normal flow volume in the east. As of this report there are no active flooding stations or high flows measured in Ohio State network of the USGS.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.

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.
