Flood Tracker provisional data from USGS streamflow monitors
Forty-eight streamflow gauges record flooding in the USA Monday, down from fifty-one Sunday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report we are watching the same 9 monitors indicating active flooding as reported yesterday: 3 in Georgia and 6 in Louisiana.
Ohio is out of frost advisory as of 8 am this morning after two nights in a row of freezing temperatures. A cold front is still impacting the Great Lakes region Monday. As of this report, none of the streamflow gauges in the Ohio network are recording high flows or active flooding.
Georgia's enters Day 47 of continuous flooding, sitting with the same three active floods monitored on the USGS network yesterday. Gulf of Mexico basin's Alapaha River is still flowing a foot above the channel at Stateville and a foot and a half over flood stage near Jennings, FL. In the Atlantic basin, Satilla River has come down overnight, running a foot and ten inches over flood stage (13 ft) near Atkinson.
New York catches the edge of the cold front on the Great Lakes Monday with just above freezing temps, clear and sunny to start off the third full week of April. No active flooding is recorded as of this report, the same station runs 99th percentile on Long Island, Swan River is high flow at East Patchogue.
Louisiana flooding remains as reported Sunday, the same six sites continue to spill over flood stage Monday. Region 1 Bayou Dorcheat is down to less than four inches of flooding near Springhill. Bayou Bodcau has levelled off, just north of ten feet above flood stage near Shreveport. In Region 4, Sabine River is down half a foot overnight, still three and a half feet over near Bon Wier, TX. Further downstream near Ruliff, Sabine River is up three inches, running two and a quarter feet over the channel. In Region 7, the east state border Pearl River continues to flood two and a quarter feet over flood stage near Bogalusa, one foot ten inches over downstream at Town of Pearl River.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.
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.
