Below normal flows persist upstate

Current Streamflows from the network of USGS river monitors in NYS
The arc of below normal streamflow activities to the west of Catskills and Adirondacks persists through the weekend into Monday. Three stations signal the lowest water levels, 1st percentile recorded for this date. For details, see the red-brown tags on the map to the right.
HABs Tracker
from National Centers for Coastal Ocean Science satellite monitoring program
from NYS Department of Environmental Conservation HAB Notifications
Six active HAB reports on the record Monday in New York State, including the same five water bodies we have been watching over the previous week. Water bodies with HABs include Wainscott Pond and Roth Pond in Suffolk County, The Lake in Central Park and Morningside Pond in New York County, and a single report of HAB upstate in the Genesee River watershed, Avon Marsh Dam Pond. As state and County agencies, citizen volunteers, lake associations and the general public begin to submit reports, NY DEC will confirm and publish reports on the notifications system. WTNY.us tags these confirmed reports to the map at the right to help recreational water users find clear access for those precious beach days. To report a suspicious algal bloom, use the on-line form here.
NCCOS uploads new satellite photos of Lake Champlain on a near daily basis. The latest image was captured June 1 at unknown surface wind speed, reported here yesterday. 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-five streamflow gauges indicate flow above flood stage in the USA Monday, up from forty-three yesterday. Two floods occur inside the WT coverage area, both in Louisiana.
The State of Louisiana reckons its surface area in watershed regions as a key organizing factor for public decision making, planning and investment. Watersheds organize the areas drained by major rivers, describing the surface area and resources in the impact zone for water-related weather, runoff of nutrients and contaminants and indicates changes in pressure on drinking water supplies and quality. Supporting the coordination of public services and administration by Parishes and municipalities to effectively manage flood, fire and other natural climatic events, WTLA.us communicates water related information using the accepted and common format in use in Louisiana. Watershed Region 4 extends from the west border with Texas to the edge of the area drained by the Calcasieu River, down to the outlet in the Gulf of Mexico. Flooding has been ongoing in Region 4 on the Sabine and Calcasieu Rivers on and off since late January. At the time of this report, Region 4 flooding continues on the Calcasieu River near Glenmora, currently signalling a gauge height five inches over the channel on a slow declining trend. West border Sabine River continues to overflow the lower channel in southwest Louisiana this morning, running the same level nine to ten inches over minor flood stage as reported here over much of the last week. NWS alerts about thunderstorms developing today and tomorrow that could overwhelm the saturated soil in the northwest Regions 1 and 2, possibly leading to flash flooding in some locations. More to follow here. 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.
