Environmental Programs & Initiatives

The Lake Hopatcong Foundation has a wide mission that involves a variety of facets of the Lake Hopatcong experience. But none of that will really matter if the health of the lake deteriorates. Because of that, we have a strong focus on maintaining and improving the lake environment.

Lake Steward Program

The Lake Hopatcong Lake Steward program aims to educate boaters about the importance of proper vessel maintenance to prevent the spread of Aquatic Invasive Species. Lake Stewards inspect boats entering the lake at Lee’s County Park Marina, remove any invasive species and educate boaters on how to prevent their spread within our lake and to other lakes.

Water Scouts

The Lake Hopatcong Water Scouts program is designed to educate people about the threat posed to the lake by the presence of invasive plants, water chestnut in particular, as well as to recruit trained volunteers to remove them.


Floating Wetland Islands

Several floating wetland islands have been installed in Ashley Cove in Jefferson Township. The plants on these islands pull phosphorus out of the water, thereby reducing the nutrients that aid aquatic plant growth in the lake.


Lake Hopatcong Guide Map

The Lake Hopatcong Foundation received a BOAT U.S. Foundation Grant in 2015 to create a Lake Hopatcong Guide Map.  Copies of the map are free and have been distributed to local businesses and municipalities around the lake. Additional copies can be obtained at our office.

Water Quality Monitoring

Water quality monitoring is essential to assess the overall health of Lake Hopatcong on a year to year basis, identifying long-term trends or changes in water quality, and quantifying and objectively assessing the success and potential impacts of restoration efforts.
