There is no question that the picocyanobacteria blooms over the past four years initiated the Highland Lake Association (HLA) to explore what has been done in the past and what can be done now to address the problem. The following is information that may help with informed participation in a Public Forum Discussion, with the Town of Windham, which is set for Wednesday, March 7 at the Windham High School auditorium.
In
reviewing a 2003 Phosphorus Control Action Plan for Highland Lake, it was
noticed that the action items called for biannual meetings of the key
stakeholders including the two Towns of Windham and Falmouth, the Highland Lake
Association as well as the Maine DEP, citizens, and the Cumberland County Soil
and Water Conservation District (CCSWCD.) It was researched, and no one
remembered ever having a meeting of those stakeholders; so the HLA approached
Windham Town Council first, since the Association had already begun a
relationship with the them, and then scheduled a combined meeting with both
Windham and Falmouth Town Managers to discuss the concept of getting together
to improve and protect the water quality.
The HLA
expected to be met with professionalism, and that’s what we got, as well as
very willing, responsible town leaders who were happy to spend the time on
forming the Highland Lake Leadership Team (HLLT), and being active
participants.
The
HLLT has formally met just three times, but the enthusiasm from all members has
been noticeable. All the committees have made great strides in outlining their
specific charge and jumping into the efforts required of each. The two towns
are working well together in identifying ordinance differences as the Ordinance
Committee looks to both towns and surrounding areas for the best practices that
will protect the lake. From the trends that the lake has experienced, it is
obvious that the existing ordinance and resident practices are not preventing
greater concentrations of phosphorus from entering the lake.
This
rise in phosphorus is very concerning, because phosphorus is the base of the
food chain within the lake and once the level gets above 10 parts per billion,
the likelihood of algae blooms is high; and while we don’t know if it is
directly related to the picocyanobacteria blooms or not, we do know that higher
levels of phosphorus will exacerbate the blooms.
The
Education and Outreach Committee is working with all the other committees to
help communicate their information, needs and results to the general
public.
This
includes the upcoming Public Forum which is reaching out to road associations
to provide guidance on best practices on roads and individual home landscaping
to minimize phosphorus exports to the lake.
The
Watershed Committee is in the process of identifying the many steps and tasks
involved with a Watershed Survey to be held on May 19. This effort will look at
the entire watershed to identify sources of phosphorus and nitrates into the
lake; then will prioritize, and make recommendations of what should be done to
address the problems.
There will
be about 50 volunteers involved in the one long-day survey. This will be the
basis used to show what problems we have, and what we need to do to address
existing conditions that are detrimental to the lake. Once this is completed, a
new Phosphorus Management Plan will be developed. Both of these efforts are
precursors to being able to apply for EPA Grant Funding, which will be
necessary to address many of the identified issues. A portion of the funding,
like in the 2005-2008 timeframe, will come from matching funds from the
community including residents and contractors.
The
whole process of reducing phosphorus export to the lake, finding the causes of
the picocyanobacteria blooms and addressing those causes likely will take about
five years to get things back in control, and then hopefully it will be much
more of a maintenance issue. The improvements will come in steps as we are able
to eliminate the problems.
Keeping
up the vigilance on the water quality through appropriate testing will tell us
if we made the progress we hoped or whether there is still much more work to
do. It is clear from the 2003 through 2008 effort, that the real danger is
complacency in not staying on top of all the threats the lake is facing.

join us for the Highland Lake Association Public Forum held on Wednesday, March
7 at the Windham High School Gymnasium at 7 p.m. For more information, please
