Seneca Lake is the largest of the glacial Finger Lakes of the U.S. state of New York, and the deepest lake entirely within the state. It is promoted as being the lake trout capital of the world, and is host of the National Lake Trout Derby. Because of its depth and relative ease of access, the US Navy uses Seneca Lake to perform test and evaluation of equipment ranging from single element transducers to complex sonar arrays and systems. The lake takes its name from the Seneca nation of Native Americans. At the north end of Seneca Lake is the city of Geneva, New York, home of Hobart and William Smith Colleges and the New York State Agricultural Experiment Station, a division of Cornell University. At the south end of the lake is the village of Watkins Glen, New York, famed for auto racing and waterfalls.
At 38 miles (61 km) long, it is the second longest of the Finger Lakes and has the largest volume, estimated at 4.2 trillion US gallons (16 km³), roughly half of the water in all the Finger Lakes. It has a maximum depth of 618 feet (188 m), and a mean depth of 291 feet (89 m). It has a surface area of 42,800 acres (173 km2).
It is fed by underground springs and replenished at a rate of 328,000 gallons (29,520 m³) per minute. These springs keep the water moving in a constant circular motion, giving it little chance to freeze over. Because of Seneca Lake's great depth its temperature remains a near-constant 39 °F (4 °C). During the summer months however, the top 10 to 15 feet (3.0 to 4.6 m) does warm up to a pleasant 70–80 °F (21–27 °C).
Seneca lake has a typical aquatic population for large deep lakes in the northeast, with coldwater fish such as Lake Trout and Atlantic Salmon inhabiting the deeper waters, and warmwater fish such as Smallmouth Bass and Yellow Perch inhabiting the shallower areas. The lake is also home to a robust population of "Sawbellies", the local term for Gizzard shad.
Over 200 years ago, there were Iroquois villages on Seneca Lake's surrounding hillsides. During the American Revolutionary War, their villages, including Kanadaseaga ("Seneca Castle"), were wiped out during the 1779 Sullivan Expedition by Continental troops under order by General George Washington to invade their homeland, destroy their dwellings and crops, and end their threat to the patriots. They destroyed nearly 50 Seneca and Cayuga villages. Today roadside signs trace Sullivan and Clinton's route along the east side of Seneca Lake where the burning of villages and crops occurred.
After the war, the Iroquois were forced to cede their land when Britain was defeated. Their millions of acres were sold and some lands in this area were granted to veterans of the army in payment for their military service. A slow stream of European-American settlers began to arrive circa 1790. Initially the settlers were without a market nearby or a way to get their crops to market. The settlers' isolation ended in 1825 with the opening of the Erie Canal.
The canal linked the Finger Lakes Region to the outside world. Steamships, barges and ferries quickly became Seneca Lake's ambassadors of commerce and trade. The former, short Crooked Lake Canal linked Seneca Lake to Keuka Lake.
Numerous canal barges sank during operations and rest on the bottom of the lake. A collection of barges at the southwest end of the lake, near the village of Watkins Glen, is being preserved and made accessible for scuba diving by the Finger Lakes Underwater Preserve Association.
The painted rocks located at the southern end of the lake on the eastern cliff face depict an American flag, Tee-pee, and several Native Americans. The older paintings, located on the bottom of the cliff, were said to have been drawn in 1779 after the Senecas escaped men from John Sullivan's campaign. However, this account is questioned by historian Barbara Bell, arguing that it is unlikely that the Senecas would have returned to paint the paintings having just escaped from Sullivan's men. She suggests instead that these paintings may have been made much later, for tourists on Seneca Lake boat tours.
It is known that the more visible and prominent paintings of the Native Americans, American flag, and Tee-pee were added in 1929 during the Sullivan Sesquicentennial. There are two mistakes in these 1929 additions: firstly the Native Americans in the Seneca Region used longhouses and not Tee-pees, and secondly the flag is displayed pointing to the left which is never to be done on a horizontal surface.
Guns of the Seneca
Seneca Lake is also the site of a strange and currently unexplained phenomenon known as Mistpouffers. In this area, they are called the Seneca Guns, Lake Drums, or Lake Guns. These are mysterious cannon-like booms and shakes that are heard and felt in the surrounding area. The term Lake Guns originated in the short story "Lake Gun" by James Fenimore Cooper in 1851. The most widely accepted explanation is sonic booms from military aircraft, though this does not explain the sounds heard during Cooper's time.
The east side of Seneca Lake was once home to a military training ground called Sampson Naval Base, primarily used during World War II. It became Sampson Air Force Base during the Korean War and was used for basic training. After Sampson AFB closed, the airfield remained as Seneca Army Airfield but was closed in 2000. The training grounds of Sampson have since been converted to a civilian picnic area called Sampson State Park.
There is still a Naval facility at Seneca Lake, the Naval Undersea Warfare Center (NUWC) Sonar test facility, where a scale model of the sonar section of the nuclear submarine USS Seawolf (SSN 21) was tested during the development of this ship.
Water quality buoy
There is a YSI EMM-2500 Buoy Platform located in the north end of Seneca Lake roughly in the center. Its coordinates are: latitude: 42°41'49.99"N, longitude: 76°55'29.93"W. The buoy has cellular modem communications and measures wind speed and direction, relative humidity, air temperature, barometric pressure, light intensity, and the water's depth and temperature, conductivity, turbidity, and chlorophyll-a levels.
The buoy was initially deployed in June 2006. The water depth where it is located is about 200 feet (61 m).
Viticulture and winemaking in the area date back to the 19th century, with the foundation of the Seneca Lake Wine Company in 1866 marking the first major winery in the area. The modern era of wine production began in the 1970s with the establishment of several wineries and the passage of the New York Farm Winery Act of 1976. The region was established as an American Viticultural Area in 1988.
Seneca Lake Wine Trail hosts many events on and around the lake, annually. With more than 30 wineries currently located on the shores of Seneca Lake, the winter 'Deck the Halls' event is a great time at the lake with participating wineries showcasing their vintages and pairing these wines with distinctive, tasty treats. Wineries also provide participants with an ornament at each stop to commemorate the event. 2011 marks the 20th anniversary of this event.
