WEEKEND WATER REPORT
Sunday, June 2, 2024


June 2, 2024 updated 1145 am EDT

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

The same five HAB reports remain on the active list Sunday, including a widespread or lakewide HAB confirmed in Wainscott Pond in Suffolk County, a large localized HAB on The Lake in Central Park south end, a widespread bloom in in Roth Pond on Stony Brook University campus in Suffolk County and a widespread HAB in 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 June 1 at unknown surface wind speed, this image is mostly clear with a good view to the open water and shorelines of Lake Champlain and its islands. No HAB activity is detected in this image. Note that low or moderate blooms are not always visible in the imaging and high wind speed can submerge the HAB mats. HABs were prevalent through the lake in late April, see the latest HAB Tracker report here for a description of the last observed HABs.


WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors

Forty-three streamflow gauges record active floodings in the USA Sunday, Saturday, down from forty-eight Saturday. Two floods occur inside the WT coverage area, both in Louisiana.

Region 5: Vermilion River breached flood briefly Sunday morning at Surrey St in Lafayette, over-running the channel from 3 am until 945 am. Peak flow was reached by 4 am and the flood is already over as of this update. Region 4 flooding continues on the Calcasieu River near Glenmora, currently signalling a gauge height seven inches over the channel on a slow declining trend. Border Sabine River continues to overflow the lower channel in southwest Louisiana this morning, running a level nine to ten inches over minor flood stage. NWS calls for showers in the northwest again today. As the ground is saturated after a week of rain, we could see more surface runoff leading to river flooding. More to follow. See black tags 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.
