WARNING SIGNS UP AT GREEN LAKE! NO SWIMMING,
WADING, WET WATER BOATING.
On Sep 12, 2014 Seattle Park Department posted signs around Green Lake
advising visitors that the lake is closed to wading, swimming, and wet
water boating activities. The lake remains open to fishing (though fish
should be thoroughly cleaned) and boating in stable boats. And the lake
remains open for Green Lake Crew to continue their training on the lake.
This closure, which remains in effect as of this date October 24, 2014,
was in response to test results from samples collected on September 11,
2014, that showed a high level of microcystin, a toxin produced by cyanobacteria
commonly known as blue-green algae growing in the lake. Earlier advisory
signs had been posted on August 22, only advising visitors of the potential
hazard from the green scum and to "Be Alert -- If in Doubt Stay Out."

The King County Department of Natural Resources is continuing weekly sample
collection and analyses for the lake. The most recent test results for
samples collected on September 26 show microcystin levels to be well in
excess of the guidance limits for recreational activities in the lake.
Test results for Green Lake are posted at the nwtoxicalgae.org
This site lists historical test results as well as the most recent. Scroll
to the bottom of the page for the most recent testing. The page is updated
as testing of samples is completed. Sample collection from Green Lake
is currently being conducted on a weekly schedule. Health Department guidelines
require that closures remain in effect until testing shows that the microcystin
level is below the guidance level of 6.0 ug/L for three consecutive weeks.
Visitors to Green Lake are advised to heed the warning signs and keep
yourself, children, and pets out of the water. Additionally it is wise
to keep in mind that the cyanobacteria (blue green algae) may show up
at other times during the year. It is wise to always heed the caution
to: Be Alert and if in Doubt Stay out.
BLAST FROM THE PAST - ALGAE
August, 2003 - Green Lake looked like pea soup but smelled like something
A Friends of Green Lake member explains the
alum treatment funding petition to a Park visitor. FOGL collected 1,500
signatures, enough to persuade the Mayor and City Council to include the
2004 alum treatment in the City Budget.
SEND A MESSAGE FOR GREEN
Green Lake is ill.
For three straight
years, toxic algae blooms have kept swimmers and dogs out of the water
in late summer and fall.
This jewel of a lake needs help. A successful alum treatment
in 2003 brought eight years of clear water. Please write a message to
the City Council Members, urging them to budget for the studies and permits
for another alum treatment. Send your message as soon as possible. They
are currently working on the budget.
Write to the City Council at USPS mail to Councilmember Nick Licata, Attn:
Emilia Sanchez, Deputy City Clerk, PO Box 94728, Seattle, WA 98124-4728;
or fax to (206) 386-9025; or e-mail to Council@Seattle.Gov. You can start
"Dear Council Member,
"Please allocate immediate funding for the studies and permitting
that are essential for cleaning up Green Lake. Without 2015 funding, there
will almost certainly be two more summer/fall seasons of toxic algae and
lake closures. Thousands of people use Green Lake every day. Please fund
its clean up!
"_______________" (Name) "_______________" (Neighborhood)
The alum treatment done in March 2004 was designed to last 10 years.
The 10 years are up. Please support FOGL efforts to keep Green Lake beautiful
and healthy. The time has come for action.
