Current Streamflow Situation
Interior streamflow monitors have recorded more seasonal normal values overnight leaving the dry area down the central drainage corridor into Long Island Sound. The dry area begins at the upper basin of the Hudson River, down through the Hudson Valley and west of the Catskills, includes Delaware River and Ramapo River with below normal and much below normal water levels as the heat advisory goes on. The highest flows today are found in the northeast Black River watershed and Long Island. Low flows show up on Ramapo River and Swan Rivers, both 1st percentile extreme low water levels. The drought map has three new watersheds represented with below normal ratings Tuesday, the Niagara River - Lake Erie watershed at north Chautauqua County, the south portion of Lake Champlain watershed in southeast Essex, the north portion of the Upper Hudson watershed in Washington County. Added yesterday, Lake Ontario minor tributaries west section remains below normal in west Monroe, Orleans and Niagara Counties. St Lawrence watershed's Raquette River channel is below normal through St. Lawrence County, lower Hudson River is below normal from northeast Orange and Dutchess Counties. As of this report, there are no floods observed in the NYS network of streamflow monitors and no extreme high flows.
WT USA Flood Tracker provisional data from the network of USGS streamflow monitors
Twenty-three streamflow gauges record flows above flood stage in the US Tuesday, the same as yesterday. WT USA tracks the flow levels on three of these reference flood events, all occurring in the state of Louisiana.
Louisiana: Bayou Bodcau Lake continues to flood the basin near Shreveport in Region 1, now two feet ten inches above minor flood stage. In Region 4, west boundary river Sabine water level is up four inches overnight near Logansport, currently recorded a foot and eight inches over minor flood stage. Flow volume has been increasing here the last few days, from 23000 cubic feet per second Sunday to 26000 cfs Monday to now more than 27000 Tuesday. Downstream to the station near Ruliff, the Sabine River runs a foot and four inches over the channel, also at 27000 cfs. For more info on the flooding in Louisiana, see black tags indicating flood flow volume and gauge height 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.

Current Streamflow Situation
The drying trend continues Monday with much below normal values popping up in the west, central and south drainage basins. Extreme low flows are showing up on the Hudson River and a Chemung River tributary in the south, as well as 1st percentile at East Patchogue on Long Island. The highest streamflow Monday is an above normal rating in the Delaware River watershed. The drought map has taken on another watershed area rated below normal, Lake Ontario minor tributaries west joins Raquette River channel through St. Lawrence River watershed and lower Hudson River at northeast Orange and Dutchess Counties. As of this report, there are no floods observed in the NYS network of streamflow monitors and no extreme high flows.
WT USA Flood Tracker provisional data from the network of USGS streamflow monitors
Twenty-three streamflow gauges record flows above flood stage in the US Monday, down from thirty yesterday. WT USA follows the water levels and volume on three of these reference flood events, all occurring in the state of Louisiana.
Louisiana: West state border Sabine River flooding near Bon Wier ended yesterday afternoon. Upstream near Logansport the flow is up overnight, currently recorded a foot and four inches over minor flood stage at increased flow volume, from 23000 to now flowing over 26000 cubic feet per second. Near Ruliff the Sabine River a foot and nine inches above the channel flowing 33 thousand cubic feet per second. Region 1 Bayou Bodcau Lake continues to recede, down five inches overnight, currently recorded three feet and an inch above the basin near Shreveport.
