GREEN LAKE MILK CARTON DERBY KICKS OFF SEAFAIR
AND SUMMER SATURDAY JULY 10
Seafair blasts onto the scene at Green Lake with the Pirate’s Booty Milk
Carton derby Saturday, July 10, 10:00 a.m.-4:00 p.m. (8:30 a.m. registration),
attracting thousands of spectators to watch more than 100 wacky milk carton
boats compete for $10,000 in prizes. A kids bounce house and plenty of
food booths, along with exhibitors, line the shores. Visit the FOGL booth
to learn more about Green Lake water quality while the kiddies make paper
fish on sticks. The race starts at the southwest corner of Green Lake,
near the Aqua Theater and the Green Lake Small Craft Center (5900 West
Green Lake Way N).
SOMETHING NEW HAS BEEN ADDED
...
FOGL has a new hat! Check out the new headgear below. The Friends of Green
Lake baseball cap sells for $15 and s made of royal blue cotton twill
with an embroidered FOGL reed logo. Profits support FOGL programs. To
order yours email FOGL.

IMPROVING WATER CLARITY
IN GREEN LAKE
Green Lake water clarity varies with the amount of suspended sediment
(clays and silts) and/or plankton (microscopic plants and animals also
known as algae) in the water. The graph below shows that water clarity
improved following the 2004 alum treatment, which continues to be effective
at reducing phytoplankton blooms. Click the image below for a larger version.
See the Monitoring page for more details.

REPORT TOXIC BLUE-GREEN ALGAE
BLOOM

Toxic blue-green algae looks pea-green in this Feb. 2008 Green Lake
pic.
The Washington Dept of Ecology has started a program to test blue-green
algae blooms for toxicity. Any blooms in Green Lake should be reported
so they can be recorded and tested.
The bloom usually looks pea-green, and can be scum or filaments or small
spheres. As the cells die, they can release pigment that is a striking
blue (see the photo below). Digital photos help document the bloom. Contact
Gayle Garman / Richard Fleming (206-525-1974), Sally Abella (206-296-8382),
or Tricia Shoblom (425-649-7288) to report a bloom.

Dec. 2007 close-up photo of the toxic blue-green algae in Green Lake!
The 2007 bloom was sampled by the County Dept. of Natural Resources and
was predominantly Anabaena flos-aquiae, which can produce a neurotoxin.
Shoreline accumulations also were seen Jan. and Feb. 2008.

FAMILY PICNIC YES - JULY MEETING NO!
The weather was perfect for our Annual
Family Potluck Picnic on July 27 on a knoll near the Bath House
Theater. Good food was shared and new friends stopped by to chat
and find out more about FOGL. The next meeting is a "non-meeting"
- it will take place by the Community Center on the east side of
the lake. We will be hunting for milfoil weevils, a natural control
of milfoil growth. Bring scuba gear!
