MLA Annual Meeting was held on July 9th, 2011
The Annual MLA Meeting was held at the Winthrop American Legion Building.
The Business Meeting was held with the election of the MLA Board of Directors.
Next years Annual Meeting is set for Saturday, July 14, 2012 at the American Legion Hall in Winthrop.
Notes taken during an outstanding annual meeting presentation by Sue Gallo, Maine Audubon Society on
Loons. Loons weigh 9-15 lbs; have solid bones. Males and females look the same, distinguished by size, males being
larger. When flying, they cruise 50-60 mph, reaching top speed of 90 mph. They need to fly fast to keep the heavy
body mass airborne. Loons usually migrate only as far as the closest coast; can get to and from wintering grounds in a
day. For Maine loons, Long Island Sound is as far as they’d go to winter. Upon return in spring, males show up first
at ice out. They actually do fly-overs from the coast and know very clearly what the ice conditions are on a nearly
daily basis, so that’s why they appear to arrive on the very day of ice out; they’ve been checking it out for a while.
They are only an hour or so in air miles away, so they can check relatively easily. Males come early to stake out
territories. Females come one week later. A family of loons eats 900 lbs of fish (mostly in the 4”-6” range) per
summer. Loons don’t breed until 7 years old. Then they usually have 2 eggs. The non-breeders are the ones we see

Annual Maranacook Lake Free ICE-OUT Contest – Win $100
The ice-out contest allows people to make their best guess on when the ice melts enough for a weight to drop through
the ice. This unit will be located on the west shore of the lower basin (Winthrop end) of the lake.
To take part in the contest, submit your guess to MLA on the enclosed form to our address.
All entries must be received no later than midnight March 20.
You must be at least 18 years of age to play the contest. All you have to do is fill out the form with your contact
information and pick the Month, Date, Hour and Minute you think the ice will melt enough for the weight to trigger
the timing mechanism. The limit is five entries per person.
The window for ice out for the past 75+ years is March 22 – May 4.
The winners will be those who guess the closest to the exact Month, Date, Hour and Minute of the winning time when
the ice at the previously mentioned location melts to sink the weight and trip the timer. In the unlikely event of a tie,
the prize will be split.

COURTESY BOAT INSPECTIONS (CBI)
Since implementation of the Courtesy Boat Inspection program at Maranacook Lake in 2004, inspectors have
completed 9,418 boat inspections! Maranacook inspections comprise approximately 20% of all Cobbossee
Watershed inspections, thereby evidencing the importance of boat inspections on Maranacook in deterring the
spread of invasive aquatic plants within the Cobbossee Watershed. In 2011, inspections increased by 6% on
Maranacook alone (compared to 2010) and increased by 2.5% overall. Funding support from your Maranacook
Lake Association, the Friends of the Cobbossee Watershed and the towns of Winthrop and Readfield allowed,
on average, 20 hours per week of coverage at both the Readfield and Norcross Point public launch sites from
Memorial Day weekend through Labor Day weekend. The two Maranacook sites are part of the ten sites
staffed throughout the Cobbossee Watershed, the largest regional CBI effort in the state!

MLA and Members help replace motor on DIVER ASSISTED SUCTION HARVESTER (DASH)
The Friends of the Cobbossee Watershed built their own Diver Assisted Suction Harvesting (DASH) unit (a pontoon
boat with a pump that provides suction for the “plant vacuum” and a hookah diving system to supply air to divers). It
is a working system that is used to remove tons of variable leaf milfoil. The Friends’ DASH boat needed a new
outboard motor to replace the old one that failed, in order to place it into service this summer. Thanks to John Blouin,
who raised the funds to get a new motor, and Clark Marine got the best price and installed it . There were a large
number of contributors, including MLA! Here comes DASH to the rescue.
