Lake Hosts are an important line of defense to catch suspicious specimens on boats and trailers that are about to enter NH lakes.  As of the end of July 2017, the NH Lakes Association reports that “Lake Hosts have now captured 14 specimens of hitchhiking invasive species this summer.”  Here’s a sampling –

Lake Sunapee – The new owner of a sailboat licensed in Vermont was told by the seller that it was last used in Lake Champlain 3 years ago.  The new owner was not educated about aquatic invasive species.  Upon trying to launch at Lake Sunapee, the Lake Host helped the new owner remove approximately 100 juvenile zebra mussels from the hull of the sailboat.  The boat was dry, and the mussels disintegrated when pinched (and therefore were not viable).  No other zebra mussels were found, and the boat was launched into the lake. 


Lake Opechee – A Water Chestnut seed was recently found by the Lake Hosts in Laconia.  The woody, dark-colored, barbed seed hitchhikes on the carpeted bunks of trailers and can start growing again even after several years of being out of the water and dormant.

The 14 invasive specimens identified by NHDES were found at the following locations:

Opechee (Laconia) – Water Chestnut seed

Monomonac (Ringe) – Eurasian Milfoil

Potanipo (Brookline) – Variable Milfoil

Sunapee (Sunapee) – Zebra mussels

Winnipesaukee (Moultonborough) – Variable Milfoil

Northwood (Northwood) – Variable Milfoil

Robinson Pond (Hudson) – Variable Milfoil
