Spy Pond, Lake in Arlington, United States

Spy Pond is a lake in Arlington, United States, covering about 103 acres (42 hectares) with a maximum depth of around 20 feet (6 meters). The pond has a irregular shoreline with several coves and points, and it is surrounded by a mix of residential areas, parks, and natural vegetation.

Spy Pond was formed by glacial activity and has been a feature of the landscape for thousands of years. In the 19th century, ice was harvested from the pond and shipped to Boston and beyond, and later the area around it was developed for housing.

Local residents often use the pond for fishing and small boating, and the surrounding paths are popular for walking and jogging. The pond's name is sometimes linked to a story about a spy during the American Revolution, though the tale is likely more legend than fact.

Visitors can access the pond from several points, including a public boat ramp and nearby parks with paths along the shore. Parking is available at some entrances, but it can be limited on weekends, so arriving early is a good idea.

The pond is home to a variety of fish, including largemouth bass and yellow perch, making it a spot for local anglers. Its shoreline includes a small island that serves as a nesting site for birds.
