Description
Seneca Lake is the largest of the glacial Finger Lakes of the U.S. state of New York, and the deepest glacial lake entirely within the state. It is promoted as 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 38 miles (61 km) long, it is the second longest of the Finger Lakes and has the largest volume, estimated at 3.81 cubic miles (15.9 km3), roughly half of the water in all the Finger Lakes. It has an average depth of 291 feet (89 m), a maximum depth of 618 feet (188 m), and a surface area of 66.9 square miles (173 km2).
