    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).

    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.

    The stock market has been going up and many investors now find that selling stocks or mutual funds will entail a large tax expense. One common way to avoid that expense, and get a full charitable deduction (if applicable), is to directly gift highly-appreciated securities to a qualified charity. 

    To qualify, securities must be held for more than one year and it is best if they are common, publicly held shares. Donating the securities in this way avoids incurring capital gains taxes that would occur if one sold the securities and then donated the proceeds. The charity receives more money. In addition, if the donor itemizes deductions (beyond the standard deduction), the full value of the securities is tax-deductible. 

    Pure Waters now has an account with Morgan Stanley that is capable of accepting securities as contributions. If you have questions, please contact Pure Waters Director, Kaitlin Fello, at Kaitlin@Senecalake.org.  To make a direct donation, contact our Morgan Stanley account manager, Steve Finewood, at Stephen.m.finewood@morganstanley.com or 315-787-3013. Tell him that you wish to donate to Seneca Lake Pure Waters Association and he will provide the instructions for you and your securities broker. 

    This is a great way to help Seneca Pure Waters preserve, protect, and promote Seneca Lake water quality.

    Seneca Lake is the largest of the Finger Lakes, containing as much freshwater as all the remaining Finger Lakes combined. In addition to supplying drinking water to over 100,000 residents, the majestic lake and its watershed drive our local economy through agriculture, wineries and breweries, tourism, and recreation.  A healthy lake is essential for all of this to occur, not just for us, but for generations to come. We are the stewards of the lake and have a responsibility to keep threats facing the lake to a minimum. 

    The mission of Seneca Lake Pure Waters Association is to preserve and protect Seneca Lake. By being a Pure Waters member, you are directly supporting our water quality activities and educational programs. 

    Seneca Pure Waters: 

    • identifies various contamination and pollution threats to the lake and its watershed

    • supports research studies

    • develops watershed management plans in collaboration with a network of partners, and

    • informs municipal and citizen practices to preserve and protect the lake and its watershed.

    Over 200 Pure Waters volunteers conduct water quality efforts that:
