Prior to undertaking the management program,
the FOSL held an informational meeting with the Town,
Lycott, SePRO (manufacturer of Sonar) and the VT DEC on
May 14, 2004 as well as a meeting with the residents around
the lake area that would be impacted by the management
program. Brochures and pamphlets were available in the
local library for review.
A whole-lake treatment was undertaken in accordance with
the permit on June 11, 2004 with Sonar AS. Samples were
collected on a weekly basis from four locations--the lake,
beach area, Mill River and ¼ mile downstream of
the dam -- to determine the fluridone concentration. The
targeted fluridone concentration was to be maintained
at 5 - 8 ppb for ninety days. Based on the results of
the FasTEST analyses, booster treatments were conducted
on June 29, July 13, August 2, and August 30, 2004. Fluridone
samples were collected and submitted to SePRO for analysis
up to and including September 28, 2004, when the sample
results from all four locations were less than 5 ppb |
Posters were erected prior to
each treatment to alert lake residents of the pending treatment
and water-use restrictions. On October 1, 2004 a letter
from the State indicated that all use restrictions were
lifted from Star Lake and the outlet stream to its confluence
with the Mill River. Upon receipt of this correspondence,
posters were erected indicating that the treatment program
was completed and successful.
On September 17, 2004 Lycott conducted a post-treatment
survey of Star Lake. Global positioning system equipment
was used to evaluate the fifteen survey areas established
by the pre-treatment surveys. The survey revealed that
the treatment program effectively managed the Eurasian
Milfoil without adversely affecting the non-target plants.
As part of the permit and five-year management plan,
a survey will be conducted during September 2005 to determine
if there has been any re-growth of Eurasian Milfoil. The
use of alternative management techniques will be reviewed
for implementation if necessary.
