HAPPENING NOW
Friday, May 31, 2024
Interior HAB reported


May 31, 2024 updated 353 pm EDT

HABs Tracker
from National Centers for Coastal Ocean Science satellite monitoring program
from NYS Department of Environmental Conservation HAB Notifications

A large localized HAB confirmed in Avon Marsh Dam Pond in Livingston County was reported by DEC staff on Wednesday May 29, the first official report from the west interior region. The Lake in Central Park has one active bloom report Friday, the large localized bloom in the south water. A lakewide HAB remains an active and confirmed report in in Roth Pond in Suffolk County, reported by Stony Brook University. Morningside Pond in Morningside Park north of Manhattan has a lakewide HAB reported May 21. 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 30 at unknown surface wind speed, this image is 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-nine streamflow gauges are recording above flood stage across the USA Friday, up from forty-four this morning. Three cases are observed in the WT coverage area, one in Georgia and two in Louisiana.

Louisiana Bayou Dorcheat flooding was short-lived near Springhill, the flow level getting back inside the channel before noon, less than eight hours of flooding recorded. While the Region 1 flood ended, another Region 4 site started taking on a large flow volume, the Calcasieu River breaching flood stage near Glenmora right after lunch hour today. This location is provisionally recorded an inch over flood stage on an increasing flow volume trend. Sabine River continues to overflow the lower channel at a higher level than reported earlier today, this could be due to tidal water influence near Ruliff TX. A flood watch remains in effect for the northwest until 1 am tonight. According to the hazardous weather outlook, thunderstorms with damaging wind gusts are the primary threat, tornadoes cannot be ruled out. See black tags indicating flow volume and gauge height, flows updated daily here.

Georgia: Atlantic basin's Satilla River is down an inch since the initial report today, five inches over the channel in Atkinson County, still coming down. We expect to see this flooding ending by this time tomorrow. See black tag indicating flow volume and gauge height, flows updated daily here.

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.
