Extreme low flow recorded in Chemung River watershed
Water news for Friday, May 10, 2024 1055 am EDT
Binghamton forecast office says rain is likely today, 70% chance of showers for the west interior region, down to 60% chance of rain tonight and 50% chance of showers Saturday and Sunday.
Current Streamflows, Drought Map from the USGS network in New York
Streamflows in the west interior run normal to below normal with much below normal values recorded in the Allegheny River watershed and one extreme low recorded in the south, Chemung River watershed. Oswego River is running much below seasonal normal as measured at the outlet into Lake Ontario. Oswego River receives the rainfall runoff from an area of 5100 square miles in the Finger Lakes region of central NYS. The northeast flows run below normal to normal with Long Island sound flows continuing normal to above normal with Mill Neck and Patchogue still seeing the much above normal flows going into the weekend.
The drought map includes an expanded area of the St. Lawrence River and adjacent Black River watersheds at below normal Friday. In the west, Niagara River - Lake Erie watershed north section has been cleared from the drought map. Allegheny, Genesee and Chemung River watersheds are rated below normal Friday, along with the Schoharie Creek channel on the west side of the Catskills heading north the Mohawk River channel, also below normal.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Eighty streamflow gauges record flooding in the USA Friday, down from eighty-eight Thursday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, nine sites record flooding on the network, four in Georgia, five in Louisiana.
After a day of tornadoes, damaging winds and heavy rainfall and flooding in north and central Georgia yesterday, Georgia is again experiencing widespread rainfall this morning. Flooding has shifted through the tributaries of the Tennessee and Coosa River watersheds over the last twenty four hours. Lookout Creek is still a foot and three inches over flood stage near New England on a sharp downward flow trend in the Tennessee River watershed. In the Coosa River watershed, Conasauga River breached flood stage around 545 pm yesterday, presently recorded flowing a foot over the channel at Tilton. Coosa tributary Coahulla Creek is still recorded at a foot and three inches over flood stage near Dalton. Oostanula River breached flood stage at Calhoun, running half a foot over at this report. Minor tributaries ended flooding within hours of starting yesterday as the rain runoff from the mountains has been collected and concentrated into larger water bodies today. Holly Creek is no longer flooding near Chatsworth, Talking Rock Creek stopped flooding near Hinton, Fausett Creek is no longer flooding near Talking Rock and the Coosawattee and Cartecay Rivers flooding ended before noon yesterday near Ellijay. See the black tags for flood volume updated daily here as the storms roll through.
Louisiana has five stations recording flood flows Friday morning. Region 4 watershed Sabine River continues to flow two to three feet out of the channel near Bon Wier, TX and Ruliff, TX. Calcasieu River runs a foot and four inches above flood stage near Glenmora. Region 1 watershed, Bayou Dorcheat appears to have peaked and leveled off, provisionally measured a foot and nine inches out of the channel near Springhill. Bayou Bodcau has dropped down to just north of five feet over the channel near Shreveport. See black tags on the map here.
Harmful Algal Bloom HAB Monitoring satellite program of the National Center for Coastal Ocean Science (NCCOS)
New York Department of Environmental Conservation surface observation of HABs monitoring season has not yet opened as of this report. Check back here for the daily update on HABs monitoring status.
The latest satellite image of Lake Champlain uploaded from NCCOS was captured May 9 at undetermined wind speed. This image is partially cloud obscured. No HAB activity is visible. A prior capture dated April 26 shows dozens of localized blooms at moderate concentration 100 thousand cells per 100 ml in various locations along the east, west and island shorelines and open water of Lake Champlain. For a description of the April 26 capture, click here or click on the HABs button to the right of the map.
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.
