Wood Creek: Wood Creek in Central New York State flows westward from the city of Rome, New York to Oneida Lake.  Its waters flow ultimately to Lake Ontario, which is the easternmost of the five Great Lakes.  Wood Creek is less than 20 mi long, but has great historical importance.  Wood Creek was a crucial, fragile link in the main 18th and early 19th century waterway connecting the Atlantic seaboard of North America and its interior beyond the Appalachian Mountains.  This waterway ran upstream from the Hudson River (at Albany, New York) along the Mohawk River.  Near present day Rome, the Mohawk River is about one mile from Wood Creek across dry land.  In the 18th century, cargo and boats were portaged between the Mohawk and Wood Creek; the crossing was called the "Oneida Carry".  In 1797, the Rome Canal was completed and finally established an all-water route.  The waterway then followed a downstream run along Wood Creek to the east end of Oneida Lake.  After a 20 mile crossing to the west end of the lake, the waterway entered the Oswego River system.  This system led either to the Lake Ontario port at Oswego, or further westward along the Seneca River.
