Lake Stewards

The Lake Steward program seeks to prevent the introduction of and/or the spread of three main aquatic invasive species: Water Chestnut, Hydrilla, and Fanwort. Studies have shown that boats and recreational equipment are among the main vectors of aquatic invasive species spread. This high-risk pathway is also one that we have the ability to do something about. While it can be intentional, often times the spread of invasives is unintentional, with the boater not realizing that there are plants or other species attached to the hull of the boat, entangled in the prop, or caught on part of the trailer or other equipment, or that moving these species around will cause a problem.

Lake Stewards, educated in AIS identification and prevention, 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. 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 (AIS) to Lake Hopatcong prevention of AIS is important to the overall health and quality of our lake.

STOP Aquatic Hitchhikers! 


  • CLEAN off  visible aquatic plants, animals, and mud from all equipment before leaving water access
  • DRAIN watercraft bilge, livewell, motor, and other water-containing devices before leaving water access.
  • DRY everything for at least five days OR wipe with a towel before reuse.

For ANGLERS, the additional step of DISPOSE is recommended:

  • DISPOSE of unwanted bait, worms, and fish parts in the trash. When keeping live bait, drain bait containers and replace with spring or dechlorinated tap water. Never dump live fish or other organisms from one water body into another.
