HAPPENING NOW
Below normal to low flows in Region 7
Sabine and Pearl River flooding coming to an end
Water news for Thursday, April 25, 2024 updated 1031 am EDT
Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Thirty-three streamflow gauges record flooding in the USA Thursday, down from forty Wednesday. 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 tracking 5 active floods monitored in the USGS network, 1 last station in south Georgia and 4 in Louisiana.
Two of six active floodings have ended overnight in Louisiana. Sabine River running the west border is no longer out of the channel near Bon Wier, TX and on the Pearl River forming the east state line, flooding has ended near Bogalusa. Flood continues on four stations Thursday. Region 1 Bayou Dorcheat has been on the rise, up half a foot overnight near Springhill. Bayou Bodcau is declining, albeit very slowly. Flow is recorded nine feet ten inches above flood stage near Shreveport. In Region 4, Sabine River still runs two feet out of the channel near Ruliff, TX. In Region 7, the east state border Pearl River still runs a foot and five inches over at the Town of Pearl River.
Georgia spring flooding is winding up on Day 50 of continuous inundation, as of 815 am this morning, down to one last station in flood stage. Alapaha River flooding is over near Jennings, FL. In the Atlantic basin, Satilla River is down to little more than an inch above the channel at Atkinson, looking to be out of this today.
The current streamflow map for NYS shows an area of below and much below normal levels in the Lake Ontario and Black Lake watersheds as the morning temperature is below freezing. A high fire danger statement issued earlier in the week indicates a drying and low humidity trend that may show up again as drought conditions develop. NYS records no active flooding as of this report, the same station runs 99th percentile on Long Island, Swan River is high flow at East Patchogue.
Ohio remains under freeze warning until 10 am this morning for the Lake Erie drainage basin Counties. Frost is expected tonight and possibly again tomorrow night in the northern counties of the Lake Erie drainage basin. As of this report, there is no active flooding recorded in the network of streamflow gauges in Ohio, there are some below normal flows in the Great Miami Basin, no extreme high or low flows, no part of Ohio is rated with 7-day average streamflows below the seasonal normal level or any degree of drought.
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.
