With the Flow – New York State Watershed Report for the Week of Nov 22-28, 2021

Over the winter months, WaterToday will be looking at New York’s state’s public drinking water systems that draw from surface water sources: creeks, rivers, lakes and reservoirs. We present the basics of a particular water treatment system with a summary from the most recent annual water quality report published. 

As before, in each weekly report, you will find a snapshot of the volume of water flowing through the state’s major rivers and their contributors, as recorded at USGS streamflow monitoring stations. The report captures your watershed flows from headwaters to outlet for a brief moment in time, as observed in the days prior to the report’s publication.

We present in this report, a list of the water bodies in each watershed that have been recommended for a Clean Water Plan, a collaboration of municipal, industrial and environmental groups working together in an overlay zoning district for the specific purpose of addressing water quality.

Finally, see the hazardous materials spills reported in each watershed in the last week. 

Take from this raw information what you need to tune in to the surface water of your landscape. WaterToday New York gathers data from EPA, USGS, NWS, NOAA sources, the accuracy is dependent on these sources.

Central NY Watersheds emptying into Atlantic Ocean at Long Island Sound

Upper Hudson River Watershed –

The Upper Hudson River Watershed drains the south side of the Adirondack Mountains, originating on Mt. Marcy and flowing south; the watershed management area extends to the Albany-Rensselaer County line. From the confluence of the Mohawk River, the Lower Hudson River gathers volume and carries on south to the Atlantic via Long Island Sound tidal estuary.

Impaired Water Bodies (3 recommended for total maximum daily load TDML plan)

These are lakes, reservoirs, rivers, or parts of rivers where water quality tests indicate the system is impaired, with excess nutrients or contaminants; the water body is placed on New York State 2018 Final Section 303 (d) list, along with the contaminant of concern and suspected source of contamination. The NYS DEC recommends the water body for a Total Maximum Daily Load (TMDL) watershed protection plan.

• Dwaas Kill and tributaries
• Ballston Lake
• Tributaries to Lake Lonely

When the impaired water body is also a drinking water source, see below.

Drinking Water Source Protection Program (DWSP2) –

According to NYS DEC advice, an overlay district is a special zoning area placed over the “base” zoning district(s) for the purpose of protecting a resource such as a waterbody or historic area, addressing a special problem, or to guide development within a special area. 

In the case of waterbodies, an overlay district may be established to protect streams, wellheads, establish buffer areas, restrict activities within buffers, and more. The overlay zone is protecting water quality by setting additional standards for development and incorporating site-specific review procedures. Overlay districts, like other comprehensive zoning tools, aid with controlling or limiting non-point source pollution and future development.

The Drinking Water Source Protection Plan should contain the overlay zone boundaries, defined standards, stakeholder engagement and review procedures. Funding may be available, consult NYS Department of Environmental Conservation. 

Drinking Water Sources:

Saratoga County: Saratoga County Water Authority (SCWA) draws and treats water from the Upper Hudson River for delivery to residents of Moreau, Wilton, Ballston Spa, Clifton Park Water Authority, Halfmoon, Malta, Stillwater Town and Village, Luther Forest Tech Campus. The treatment plant uses a coagulant, membrane filtration and active carbon filtration, followed by pH adjustment with soda and an anti-corrosive. As of 2020 annual report, the water supply was clear of the common contaminants. Check the Annual Water Quality Report at SCWA online. Mechanicville draws drinking water from the Mechanicville Reservoir; Saratoga Springs draws from Loughberry Lake.

Upper Hudson River – Black River Regulating District planned release volume for the week of Nov 22-29:

• Great Sacandaga Lake reservoir set to release 3600 cfs Monday, 3800 cfs Tues Nov 23 and 4000 cfs daily through the rest of the week.
• Indian Lake 405 cfs release Monday, 404 cfs Tues/Wed and 403 cfs through the rest of the week
• Stillwater Reservoirs is set to release 600 cfs daily
• Sixth Lake Reservoir will release approximately 73 cfs the first half of the week, and 72 cfs to the end of the week
• Old Forge Reservoir will be releasing 173 cfs Monday, stepping down gradually to 169 cfs by end of the week

Washington County: Fort Edward draws water from four reservoirs, according to Hudson Riverkeepers.

Warren County: Queensbury, Glens Falls draw from Upper Hudson River.

Rensselaer County: The Tomhannock Reservoir near Troy is the drinking water source for several communities, including Troy, Brunswick, East Greenbush, North Greenbush, Poestenkill and Schaghticoke, Waterford, Schuylerville, Victory, Menands and Rensselaer. As of May 2021, two cast iron main lines installed in 1914 are being replaced from the Tomhannock Reservoir to the water treatment plant. The four miles of pipe for this project is estimated to take another year to year and a half to complete.

Drinking Water Source Profile: Hinckley Reservoir (01343900)– (from USGS Water Quality Watch)

Located on West Canada Creek in Herkimer County, Hinckley Reservoir collects streamflow from an undeveloped natural area of 374 square miles in the Adirondack Mountains, and supplies drinking water for the City of Utica. The earth and concrete dam began storing water in 1914, with diversion for the city of Utica beginning several years later. Drinking water treatment and distribution is provided by Mohawk Valley Water Authority, serving 126,250 customers through 650 miles of pipe to 38,900 service connections. The water treatment plant at Prospect (1992) double filters to remove organic matter and chlorinates the water to kill bacteria. Fluoride is added, along with lime and soda ash to render the water non-corrosive to pipes and plumbing. Water quality is monitored by the MVWA certified laboratory staff. The Annual Water Quality Report 2020 is available here https://www.mvwa.us/WaterQuality/2020AWQR.pdf

Hinckley Reservoir was selected for intensive (monthly) sampling through the NYSDEC Division of Water’s Lake Classification and Inventory (LCI) program in the summer of 2011. The lake was classified as mesotrophic, or moderately productive. (Lake Classification and Inventory Survey, Lake Water Summary, Newman et al, NYS DEC 2011)
