HAPPENING NOW
LA hosts the last flooding in the network
Walnut Bayou Water, Carencro BWAs
Water news for Friday, April 26, 2024 update 909 am EDT
Drinking Water Matters
Lafayette Parish: Carencro water customers have come under a BWA this week. Customers on North Street, John Street and St. Charles Street were impacted with the boil order following repair of a water line in the area Wednesday.
Madison Parish: Walnut Bayou Water Association issued a BWA Wednesday impacting customer connections west of the City of Tallulah. The advisory applies to certain addresses on Hwy 80 West, Gregory Rd, Cox Rd, Averett Rd, Lance Morgan Rd, Quebec Rd, Hilderbrand Rd, Eldorado Plantation Drive and Butts Drive until further notice.
Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Thirty-seven streamflow gauges record flooding in the USA Friday, up from thirty-three Thursday. 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 4 active floods monitored in the USGS network, all four in Louisiana.
Flooding continues on the same four USGS streamflow monitoring stations as reported here Thursday. Region 1 Bayou Dorcheat is up again overnight near Springhill. Bayou Bodcau is slowly declining near Shreveport, still running well above nine feet over flood stage heading into the weekend. In Region 4, Sabine River is down half a foot overnight, running a foot and a half out of the channel near Ruliff, TX. In Region 7, the east state border Pearl River has come down significantly overnight, running nine inches over flood stage at the Town of Pearl River.
Georgia's spring flooding has finally come to an end. As of around 5 pm yesterday, Satilla River tucked back inside the channel at Atkinson, ending Georgia's fifty straight days with flooding. Satilla River came within an inch of ending the flood in early April when another widespread rain event spiked another two weeks of flooding in the south. This time, flooding appears to have ended at all USGS monitored sites in Georgia. Once again, Atkinson was the last station to see the 2024 spring floodwater go.
The current streamflow map for NYS shows an even mix of normal and below normal flows statewide. Lake Ontario minor tributaries west section and Black Lake watershed have a significant number of much below normal streamflow values, lending the north Counties a place on the drought map. 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.
Parts of north Ohio are just shaking off a freeze overnight. The NWS Freeze Advisory came off at 9 am this morning for Lake Erie drainage basin Counties. A handful of below normal rated flows are popping up in the Great Miami and Scioto River basins with the first below normal rating to show up on the Ohio drought map in many weeks. Little Muskingum River basin is rated below normal Friday from northeast Washington, through Noble and Monroe Counties. As of this report, there are no extreme high or low flows.
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.
