Otisco Lake
Otisco Lake is the easternmost of New York's eleven Finger Lakes. The 2,048-acre (8.29 km2) lake is located in Onondaga County, southwest of the city of Syracuse.
History
Otisco Lake's name may have been derived from the Iroquois name for the lake's outlet, Nine Mile Creek, Us-te-ke, meaning "bitter-nut-hickory". At least one older map, published in 1825, has the name spelled as "Ostisco". The name may also have been derived from the word ostickney, meaning "waters much dried away", or from the Onondaga word ostick, meaning "the water is low".
Prior to European settlement, the lake was used by the Onondaga people for seasonal fishing and hunting, however no permanent settlements were known to exist. After the Revolutionary War, lands surrounding Otisco Lake were given to soldiers as payment for their service in the war. The first house was erected near the head of Otisco Lake by Oliver Tuttle in 1804, in what is today the Town of Otisco.
In 1869, Otisco Lake was made larger with the construction of a dam near the lake's outlet, which enabled the lake to be used as a reservoir for the Erie Canal. The dam's construction raised lake levels by nine feet (2.7 m), and flooded a road at the southern end of the lake. To re-build the road, a causeway was built out of hemlock logs. The causeway was damaged by storms and allowed to deteriorate before being reconstructed in 1983.
