Wainscott Pond HAB
June 1, 2024 827 am EDT
HABs Tracker
from National Centers for Coastal Ocean Science satellite monitoring program
from NYS Department of Environmental Conservation HAB Notifications
Five active HAB reports are logged with NY DEC Saturday including a widespread or lakewide HAB confirmed in Wainscott Pond in Suffolk Country. The report was submitted by Stony Brook University on Wednesday May 29. The Lake in Central Park has an active HAB report, a large localized bloom in the south end of the water body. Widespread or lakewide HABs active in Roth Pond in Suffolk County and Morningside Pond in Morningside Park, Manhattan. See active HABs tagged on the map to the right. To report a suspicious algal bloom, use the on-line form here.
NCCOS uploads a new satellite photo of Lake Champlain daily. The latest image was captured May 31 at unknown surface wind speed, this image is completely cloud obscured. A previous image captured May 30 was mostly clear with no HAB activity detected. See the latest HAB Tracker report here.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Forty-eight streamflow gauges record active flood events in the USGS network nationally Saturday, down from forty-nine Friday. Two cases of flooding are observed in the WT coverage area Saturday morning, both of these in Louisiana.
Louisiana Mermentau River breached flood stage at Mermentau in watershed Region 5 for approximately an hour, between 3 am and 4 this morning, currently recorded two inches below flood stage and declining. This is a tidal water body and tends to be up and down daily, though not to the point of flooding. Region 4 flooding continues on the Calcasieu River near Glenmora, currently nine inches above the channel. Border Sabine River continues to overflow the lower channel in southwest Louisiana this morning, also nine inches over the channel, also influenced by the tide near Ruliff TX. A flood watch has passed for northwest Louisiana and a new hazardous weather outlook has been issued for a disturbance across north Texas that will bring strong to severe storms to northwest LA today. According to the hazardous weather outlook, thunderstorms with damaging wind gusts are the primary threat, and more showers expected tomorrow. See black tags indicating flow volume and gauge height, flows updated daily here.
Georgia: Georgia is out of the flooding game Saturday as Atlantic basin's Satilla River retreated back into the channel at the last observed flooding location, lower channel in Atkinson County just before six this morning. As of this report, Satilla is half an inch under flood stage on a steady declining flow trend.
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.
