Flood Tracker provisional data from USGS streamflow monitors
Twenty streamflow gauges record flood stage in continental USA Saturday, down from twenty-four this time yesterday.
WT tracks flooding at twelve of these locations, six located in Georgia and six in Louisiana. As of this report, NY and OH are not seeing active flooding in the USGS network. More to follow as the rain falls on NYC and flood watch in effect.
Two streamflow gauges have begun lighting up the flood map Saturday afternoon, reaching 99th percentile flows on Long Island, NY, currently under NWS Flood Watch. Valley Stream is flowing high at Valley Stream, running 1.82 ft deep at 42.9 cubic feet per second. A tributary to Bellmore Creek is flowing 99th percentile at Bellmore, running 2.64 ft deep at 16.6 cubic feet per second. These monitoring stations do not have established flood stages, so we will not know when overflow occurs. Local weather spotters are encouraged to report to NWS.

Two rivers continue to flood in south Georgia Saturday. Altamaha River began to show the first signs of slowing down at its top end Thursday, receding half a foot overnight. As of this report, the flood level measured near Charlotteville is just over half a foot above flood stage. Downstream monitors near Baxley, at Doctortown and at Everett City record water levels from half a foot to three feet over. Flow volume provisional data captures the reduced volume Saturday, from 33 thousand Friday down to 28600 cubic feet per second near Charlotteville, the bulk of flood water has shifted downstream toward the outlet, still above 60 thousand cubic feet per second moving through Everett City to the outlet at Brunswick. Savannah River is still chugging along a foot and a half above flood stage near Milhaven and four feet out of the channel near Cylo.

Louisiana records flooding on the same six monitors Saturday. In Region 1 watershed in the northwest, Bayou Dorcheat runs two feet over flood stage near Springhill, a foot and inches over flood stage downstream at Minden, trending down. Bayou Bodcau has levelled off overnight, still six feet above flood stage near Shreveport. In Region 4 in the southwest, Sabine River runs six inches above flood stage according to the monitor located near Ruliff, TX. In the east, Pearl River holds a steady two and a half feet above flood stage spreading out at 331800 cubic feet per second near Bogalusa, more than two and a half feet over downstream at the municipality of Pearl River.

EPA announces the release of the 2022 Toxics Release Inventory (TRI) National Analysis with positive news.
Toxic chemical releases have declined 21% in 10 years according to new TRI data.
From the announcement received March 21, 2024, "environmental releases of TRI chemicals from facilities covered by the program were 21% lower in 2022 compared to 2013. This includes a 26% decrease in air releases. During this 10-year period, releases from manufacturing facilities decreased by 9% while the value added to the U.S. economy from manufacturing increased by 14%. While overall releases increased by 1% from 2021 to 2022, there was a 6.5% increase in the number of pollution prevention activities reported under the TRI Program compared to 2021."

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.
