Lake Host Program

The Lake Host™ Program is a courtesy boat inspection program administered by NH LAKES in cooperation with local participating groups to prevent the introduction and spread of aquatic invasive species, plants and animals, from waterbody to waterbody.

Infestations of invasive species such as variable milfoil and Asian Clams in our waterbodies are undesirable because: they make recreation in and on the water dangerous and unpleasant; they disrupt the ecological balance of waterbodies; they reduce shoreline property values; and they are difficult and expensive to control.

 NH Waterbodies with Aquatic Invasive Species Infestations


Trained Lake Hosts staff boat ramps to:

  • Educate visiting boaters about aquatic invasive species (plants and animals)
  • Conduct a brief boater survey
  • Teach boaters the “Clean, Drain & Dry” method for preventing the spread of aquatic invasive species
  • Conduct courtesy boat and trailer inspections to remove all hitchhiking aquatic invasive species and native species, too
  • Remind boaters to always open/remove drain plugs before trailering from the ramp and to leave all drain plugs open/out while transporting
  • Send suspicious species fragments to the New Hampshire Department of Environmental Services for identificationHPIM0595.JPG

Since 2002, hundreds of paid and volunteer Lake Hosts have conducted more than 851,102 courtesy boat inspections and have made more than 1,550 ‘saves’ of aquatic invasive plant or animal specimens that were about to enter or had just left a waterbody.

Lake Host Program for ramps not open to the general public:

Community groups, marinas, and owners of ramps not open to the public are invited to participate in NH LAKES Lake Host Program on a non payroll-grant award basis. NH LAKES can hire individuals to work as NH LAKES Lake Hosts at these ramps not open to the general public, provided that the local group provides funding to cover salaries and associated taxes, statutory benefits including insurances, and payroll fees.

Lake Host Program for ramps open to the general public:

The Lake Host Payroll Grant Program is open to groups (lake, pond, river and watershed associations, municipalities, and other community groups) that pledge to staff boat ramps open to the general public. NH LAKES provides (‘sets aside’) grant funding to cover the salaries and benefits of individuals hired as NH LAKES employees to work as Lake Hosts at local ramps open to the public. Participating groups are required to match their payroll award by a minimum of 100% by providing volunteer labor and/or by contributing funding to extend Lake Host employee coverage at their ramp. Funding for the payroll grant award programs comes from the New Hampshire Department of Environmental Services’ Exotic Species Prevention Grant Program which is funded by a portion of the revenue generated by in-state boat registration fees. Funding for the payroll grant program also comes from foundations and local sources.

2017 Lake Host™ Payroll Grant Program

We are pleased to offer the Lake HostTM Program, one of the nation’s premier aquatic invasive species education and prevention programs, for its 16th year! With grant funding support from the New Hampshire Department of Environmental Services, the Alden N. Young Trust, TransCanada, and a Federal Supplemental Environmental Project, we have awarded payroll grants to approximately 85 local groups to staff 108 of the most highly used boat ramps throughout the state with trained NH LAKES Lake Host employees. Local groups, individuals, and municipalities have also contributed funds to provide for additional Lake Host staff time and have also contributed hundreds of hours in volunteer Lake Host time.
