The Lake Hopatcong Foundation supports the lake and the community surrounding it with our community calendar. If you have a free event or event that benefits the Lake Hopatcong community (Hopatcong, Jefferson, Mt. Arlington or Roxbury) and is open to the public within the four towns surrounding the lake, fill out the community calendar form to be included on our website. We also provide important lake safety phone numbers on our Lake Public Safety page.

We have information on our website regarding the annual weed harvest and water level management plan as a courtesy post. We do not run these programs. The aforementioned programs are run by the State of New Jersey through the Department of Environmental Protection – State Park Service.
