A New Hampshire lake during summer


Lake Host On Duty

NH LAKES is pleased to offer the Lake Host Program, an aquatic invasive species education and prevention program for the 20th year!

Lake Hosts work at boat ramps throughout the state checking boats for hitchhiking aquatic invasive species, and teaching people about the Clean, Drain, & Dry method to keep invasive plants and animals out of our lakes. Each summer, approximately 400 volunteers and 300 employees are trained to work as Lake Host Inspectors. 

Grant funds and locally-contributed funds are allocated to Lake Host employee paychecks. You can add MORE Lake Host coverage to your favorite lake by making a tax-deductible donation today through Lake Host Charitable Giving! To donate, click here.
