Lake Host

The Lake Host Program​

Clean water, healthy wildlife, and stable property values depend on a healthy lake free of invasive species. The NH LAKES Lake Host Program is the first line of defense in protecting our lakes from invasive plants and animals.

These lake heroes protect the lakes you love by capturing invasive species that try to sneak in on boats, trailers, and gear. 

They offer free complimentary boat inspections to teach boaters about the Clean, Drain, and Dry method for aquatic invasive species prevention.

You can expect to meet a Lake Host at some of the most popular New Hampshire boat launch sites. Look for the iconic uniform—a royal blue t-shirt and a big smile!

Clean, Drain, and Dry

Don’t let aquatic invasive species invade our precious lakes. Once they arrive, they may never leave. Practice the clean, drain, and dry method to stop the spread.

Do you think you’ve seen an aquatic invasive plant or animal lurking in the water or hitchhiking on a boat, trailer, or other recreational gear? Learn what they look like and how to report them.
