The River Cam is a tributary of the River Great Ouse in the east of England. The two rivers join to the south of Ely at Pope's Corner. The Great Ouse connects the Cam to England's canal system (via the Middle Level Navigations and the River Nene) and to the North Sea at King's Lynn. The total distance from Cambridge to the sea is about 40 mi (64 km).
