It is believed that the milfoil species we have in the lake came from an overflow of Scobie Pond in
Francistown, as a result of the Mothers Day Flood of 2006.

In July of 2006, a sample was sent to NH-DES for DNA sampling and identification.

The species was confirmed by November of 2006.  This specific variety does very well in the
acidic waters in NH.  It will continue to spread, and grow up to 1 inch per day.  Once reaching the
surface, it will spread out along the surface, and continue to grow and spread.  There is no known
biological solution to prevent this variety from growth, though UNH is working on engineering a
weevil to do so.  This variety does not die from freezing, it will instead change to a cactus like state
in the cold, and be ready to grow again when the warmer weather arrives. The only known State
approved method of dealing with this variety in an infested area this size, is the use of an
herbicide.

In 2007, the State set their sites on addressing the issues up river first (Scobie Pond), with the
intent of mapping out the infestation in our Lake during the summer of 2007.

In the summer of 2007, the infestation was mapped out by DES:

map.  This map shows 94.2 acres of 192.5 acres (or 49%) infested as of the summer of 2007.
DES  also mapped out small localized outbreaks in Glenn Lake.

In the Spring of 2008, Amy Smagula updated residents of the Lake at a meeting held at Goffstown
Town Hall (
click here for link to meeting notes).  She reported that Glenn lake was being treated in
the Spring of 2008, and that our Lake could be treated as early as the Spring of 2009.  She
informed us that an organization, or municipality must submit a grant request to the DES by
September 15th in order to tap into State matching funds.

In July of 2008, this Association was formed to accomplish this.

In September of 2008, DES updated the infestation map:
