Seneca Falls BWA
June 24, 2024 updated 1015 am EDT
Drinking Water Advisories
Seneca Falls came under a BWA Friday following repair of a water main. The BWA impacted those customers connecting north of the canal, extending west to Rumsey Street. Seneca Falls WTP operates with permit NY4901198, serves a population of 9400 residential customers from a surface water source in Cayuga Lake. The Town of Seneca Falls operates with permit NY490011, the 2023 Annual Water Quality report states 9000 served from a raw water intake in Cayuga Lake, 25 feet below the surface. As Cayuga Lake is noted with active HAB reports, WT will track microcystins test results here. More to follow.
Current Streamflow Situation
The central and northeast surface waterways of NYS have been replenished and refreshed over the weekend, a relief for the stress on aquatic environments and water quality caused by low flow combined with high heat. Current streamflows are rated normal to much above normal in the northeast Monday morning, and seasonal normal through the central southwest and southeast drainage basins.
The highest flows are found in the northeast, predominantly running above normal to much above seasonal normal. A single instance of high flow is recorded on a Hudson River tributary, 97th percentile near Milton. The lowest flows found in NYS Monday are in the Lake Ontario minor tributaries west and lower end of Genesee River watershed. A single incidence of low flow is found on a minor tributary of Lake Ontario, Northrup Creek flowing 2nd percentile at North Greece. As of this reporting, there are no active floods, no 99th percentile extreme high flows or 1st percentile extreme low flows to report.
On the drought map, Lake Ontario minor tributaries west section has taken on the deep red color defining severe hydrologic drought, for 7-day average streamflows calculated much below the seasonal normal. Also on the drought map at the start of the new work week, Niagara-Lake Erie and Oswego River - Finger Lakes interior portions are below normal, the shoreline areas are not rated.
From The Sensors provisional data on river flooding from the network of USGS streamflow monitors
Seventy-six streamflow gauges indicate flooding in the USA Monday morning, up from seventy-three Sunday. The majority of these floods are recorded in the midwest states of Minnesota, Wisconsin, South Dakota. Within the WT coverage area of New York, Ohio, Georgia and Louisiana, just two floods events remain, both in Louisiana.
Louisiana: Region 7 Amite River flooding ended at Hwy 22 near Maurepas over the weekend, currently a foot below flood stage. West border Sabine River flooding ended Sunday morning near Logansport leaving Region 1 Bayou Bodcau Lake on the flood dashboard, currently recorded just three inches above the basin. Bayou Bodcay Lake may be back inside as of this report, ending the flooding that began near Shreveport June 4. In Region 4, west boundary river Sabine continues to spill out of the channel near Ruliff, TX, still seven or eight inches above flood stage with a consistent flow volume 17000 cfs as reported yesterday. 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.
