After a great deal of debate, the Pure Waters’ Board of Directors has made the tough decision to cancel our Annual Dinner for this year. As you might expect, the Covid Delta variant was at the center of our decision. At first, we thought having proof of vaccination might be sufficient to guard against the Delta variant. However, the Board concluded the risk was too great to proceed, and determined we should not risk the health of our loyal members.
The Annual Dinner is always one of our most popular events and also one of our biggest fundraisers. However, like last year, we will work diligently to make up for this significant revenue loss. We will find creative ways to fund and support our well- respected water quality monitoring programs, including HAB Bloom, Stream, Lake Assessment (CSLAP), and Invasive Species Management (PRISM) as well as our educational Lake Friendly Living program. You can donate any time at www.senecalake.org/donate or contact our Association Director, Kaitlin Fello (firstname.lastname@example.org ), if you would like to help us in our funding efforts.
In addition, we would like everyone to know our Virtual Annual Meeting will take place on October 13, 2021, from 5:00 p.m. - 7:00 p.m. Please save the date and join us while we discuss our year in review and our plans for the future. The Virtual Annual Meeting will be preceded again this year by our Virtual Silent Auction. Be ready to start the bidding on your favorite item on Friday, October 8, through Friday, October 15. We hope you will join us for some fundraising fun and bid on your favorite special packages that week! If you are interested in donating to this year’s silent auction, please email Kaitlin at email@example.com.

By 12:00am on 8/19, discharge peaked from Keuka Outlet at Dresden at 3290 cubic feet per second(cfs). Discharge rates continued above 2000cfs until approximately 10:00am that same morning.
Manhole 360 (DEC)/ 135 Seneca Street.
Seneca Pure Waters recently had a meeting with the representatives from the D.E.C. Regional 8 office. Although the New York Sewage Right to Know alert originally reported a spillage of over 34 million gallons, D.E.C. officials indicated that the volume was miscalculated, and subsequent alerts were corrected. In reality, approximately 177,000 gallons of sewage spilled into the Keuka Outlet, and towards Seneca Lake.
The NYS Alerts also revealed the location of the incident: 135 Seneca Street, Penn Yan. This property sits directly adjacent to The Birkett Mills.

On Tuesday, July 20th, Seneca Lake’s lake-level climbed to a recent high of 446.68 feet above sea level, almost five inches above the Summer upper target of 446.3 feet. Since then, the lake level has fallen to the Gordon Hansen Seneca Lake Rule Curve target range of 446 +/- .3 feet.
The Seneca Lake Rule Curve, developed in the mid-70s by Gordon Hansen of the Navy’s Underwater System Center at Dresden, defines the lake’s highest and lowest tolerable levels. Rule curves establish a target range for the water level, helping to prevent severe flooding or severe drought conditions, and ensuring a stable, reliable water supply throughout low water summer months and protecting damage to delicate natural resources during high water months.
For reference, the Rule Curve for Seneca Lake predicts minor flood damage at about 447.8 feet, and major flood damage at 448.5 feet. The 100-year flood level for Seneca Lake is 449.9 feet, which has not been reached since the first Seneca Lake level record in October 1 of 1956. After the Dundee/Lodi storms in 2018, the lake rose about 12 inches in 12 hours topping out at 447 feet. Seneca Lake levels have reached to 447+ feet eight times since USGS began recording lake level data.
Each finger lake has a Rule Curve to guide its water level management, but there is only voluntary coordination among the lakes to manage both lake level and water discharge from each lake. Water can flow into Seneca Lake faster than it can flow out, since the downstream area is relatively flat and the outflow is regulated; therefore, the lake level rises after a rapid snow melt or big rain event.
The outflow of Keuka Lake, which drains directly into Seneca via the Keuka Outlet, is controlled by the Keuka Lake Outlet Compact (KLOC)—an intermunicipal organization representing the eight municipalities around Keuka Lake. Its primary purpose is to regulate Keuka Lake level using six outlet gates located at the Main Street bridge in Penn Yan, NY.
To minimize the risk of downstream flooding, the "Reservoir Regulation Manual-Keuka Lake Outlet" (developed by the Army Corps of Engineers), limits the discharge rate to 1,000 cubic feet per second (cfs). To achieve this maximum discharge rate, the Keuka Lake level must be at least 716.03 feet with all six gates open. On July 17th and 18th, the Keuka Outlet gage at Dresden, NY recorded two consecutive hours of more than 1,000 cfs (1,020 cfs to 1,300 cfs) which is due to both Keuka Lake outflow and precipitation in the Keuka Lake Outlet subwatershed. Although the Keuka Outlet was flowing high on these dates, there were no reports of significant damage due to the controlled outflow from Keuka Lake (Both residents and businesses on the west side of Seneca Lake near Himrod saw property damage during and after the recent rainfall event. Most reported damage was due to small stream spillover).

Education & Community Outreach
The Seneca Lake Pure Waters Association is now looking for volunteers for a growing program that aims to engage and educate watershed residents on the health of the lake, and find ways to partner with like-minded organizations to create new outreach opportunities. As an education and community outreach volunteer, you could expect to:
Plan and execute educational webinars, workshops, and forums for the public to attend and learn.
Partner with other local organizations to bring a variety of experts and educational opportunities to watershed residents.
Seek new outreach possibilities to expand Seneca Pure Waters’ brand recognition and the understanding of Lake health issues and best practices.
Serving as an Education and Outreach volunteer would be a natural fit for anyone who feels passionate about educating all ages on preserving and protecting Seneca Lake. This group of volunteers would meet once monthly, with some efforts needed outside of regular meetings.
Lake Friendly Living Committee
Pure Waters Lake Friendly Living Program seeks volunteers to help promote and educate residents about home practices that can have a positive impact on our lake. As a Lake Friendly Program volunteer, your role can cover a variety of promotion and education needs including:
Introduce the program to your community through meetings with your social, religious and professional groups. Pure Waters will provide you with information and materials.
Organize a workshop on “how to’s” related to landscape techniques such as planting rain gardens, buffers and native greenery, installing a rain barrel or permeable surfaces, or any other Lake Friendly Living technique that you find on our LFL webpage – www.senecalake.org/lakefriendlyliving .

Due to frequent and unpredictable rainfall events, a section of farmland in the Seneca Lake Watershed had been experiencing persistent erosion and flooding issues. Although the farmland had been treated well with good management practices including strip crops, cover cropping, and reduced tillage practices, it still experienced significant flooding and erosion issues.
After a watershed analysis was completed of the area, a decision was made for the Yates County Soil and Water Conservation District to install two stormwater retention basins (officially referred to as Water and Sediment Control Outlet Basins). Stormwater basins have been constructed for many years around the watershed and are a proven, useful land management practice. The basins take the peak flow of water, store it, and slowly release it which reduces downslope flooding and erosion.
The basins are strategically placed in the landscape to allow for the most water storage capacity. For this project in Yates County, approximately 2,700 feet of 6-inch plastic drain tile and 600 feet of 4-inch plastic drain tile was used to outlet the water from the basins to a downslope, stable area. The basins were constructed in the middle of the farmland so extra sloping work was completed to keep the loss of farmland to a minimum. Over 1,300 cubic yards of soil were moved. After construction, only 0.3 acres of farmland were lost for the basins and the farm has seeded those areas to a wildflower mix for beneficial insects.
This project was made possible through funding by the Finger-Lakes Lake Ontario Watershed Protection Alliance.
