Lake Information for Greenwood Lake

Greenwood Lake is an interstate lake approximately seven miles (12 km) long, straddling the border of New Jersey and New York. It is located in West Milford, New Jersey (in Passaic County) and Greenwood Lake, New York (in Orange County).

The lake was originally called "Quampium" by the Munsee Native Americans who lived there. It was renamed "Long Pond" by Europeans, who settled the area in the 1700s for farming and ironmaking, and eventually came to be re-christened "Greenwood Lake." It was dammed up in 1837 to increase the size of the lake for water power downstream.

The enlarged lake began to attract tourists. During its resort era, several steamboats operated on the lake, including the Greenwood Lake Transportation Company's "Arlington" and "Milford", and their side-wheeler, "Montclair", built in 1876, which had two decks and is reported to have been capable of carrying from 200 to 400 passengers. These steamboats met the trains and took passengers to the various resorts around the lake in both states.
