Blydenburgh County Park is one of the largest parks in Suffolk County, spanning 627 acres of rolling, wooded terrain in Smithtown, Long Island. The park has long been centered around Stump Pond — however, in August 2024, severe flash flooding caused the dam to collapse, completely draining the pond.
