The Lake Hopatcong Guide offers boaters and other Lake Hopatcong residents and visitors the opportunity to see a map of businesses and historical sites around the lake (with information and photos), kayak launch points, hiking trails, an events calendar, lake news, weather, useful links, and more. There’s a button to quickly call the N.J. State Police, and a warning will come up automatically if the high-water no-wake restriction is in effect. This free app was developed as part of an initiative from the Lake Hopatcong Foundation, a 501c3 nonprofit organization.
