Gardner Lake State Park is a public recreation area occupying on the southern edge of Gardner Lake in the town of Salem, Connecticut. The state park offers opportunities for boating, fishing, and swimming and is managed by the Connecticut Department of Energy and Environmental Protection.
For most of the 20th century, the site of the state park was a private resort. The state purchased the site in 2001 for $550,000 after previous efforts to purchase it in the 1990s by local government were rejected by voters. In 2008, the state invested $1 million dollars in improvements to the park's boat launch and parking area. Those improved facilities contributed to a marked upturn in public use.
The park offers a swimming beach and boat launch. Gardner Lake covers and is a state-designated bass management lake.
In 2012, 2013, and 2016, reports of disruptive behavior and the failure of visitors to pack out trash led to calls for increased vigilance by authorities and more cooperation from the public.
