Lake Carnegie, Rowing and canoeing reservoir in Princeton, United States.

Lake Carnegie is a reservoir on the southern edge of Princeton University that stretches for several miles. The water body connects with the Millstone River and the Delaware-Raritan Canal, creating a broad surface for various activities.

The lake was built in 1906 and was the first water body in the United States designed specifically for competitive rowing. This construction set a new standard for sports facilities and supported the growth of rowing in America.

The lake serves as a training ground for Princeton University's rowing teams and provides recreational opportunities for the local community. People use the water regularly for sport and leisure.

The boat launch area near Route 27 is open from sunrise to sunset with restrictions on gasoline-powered boats. Swimming is not permitted, but rowers and paddlers find ideal conditions for their activities.

Albert Einstein visited the lake with his friend Johanna Fantova, who recorded their experiences in her personal diary. This connection shows how the water became part of the daily life of prominent figures in Princeton.
