Lake Champlain HAB watch
May 28, 2024 931 am EDT
HABs in New York
National Centers for Coastal Ocean Science (NCCOS) HAB monitoring program uploads a new satellite photo of Lake Champlain daily for interpretation of harmful algal bloom (HAB) presence, extent and concentration. The latest image was captured May 27 at unknown surface wind speed, this image is completely cloud obscured with no view to the open water or shorelines. An image taken May 26 allows view to water and shorelines between cloud breaks with no HAB activity visible. Any HAB observed in these photos is matched with a color scale for concentration given in cells per 100 ml sample. See the latest HAB Tracker report here.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Forty-one streamflow gauges are in flood Tuesday, down from forty-nine yesterday. Three gauges in the US network indicate flooding in the WT coverage area, one in Georgia, and two in Louisiana.
Louisiana Region 1 Bayou Bodcau is running an inch over the basin near Shreveport, looking to end the flooding that began here in the end of January. NWS forecast for this week indicates locally heavy rain with possibility for flash flooding in Region 1. More to follow. Region 4 border river Sabine runs over the channel at the lower end near Ruliff on Tuesday morning, nine inches above flood stage, not much change from yesterday. See black tags indicating flow volume and gauge height, flows updated daily here.
Georgia: Satilla River collects surface runoff from 2790 square miles in Coffee, Atkinson, Pierce, Bacon Counties on the Atlantic Ocean side of the divide, down to less than two feet of flood water measured above the channel in Atkinson County. 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.
