Seneca Lake Professional Review and Guide
"While locals disagree on which is the biggest Finger Lake, Seneca holds the most water, over four trillion gallons. Covering 43,343 acres and up to 3 miles wide and 35 miles long, this lake’s average depth is just under 300 feet, and its maximum depth is 618 feet—deep enough for the military to keep a couple of deepwater research barges out in the middle year-round.
Half the shoreline is developed and includes the city of Geneva and the village of Watkins Glen, cradle of the American Grand Prix and current home of the Watkins Glen International of NASCAR fame. Key species: Lake trout, brown trout, rainbow trout, landlocked Atlantic salmon, black bass, northern pike, and yellow perch"
