AUDIENCE COMMENTS
Mr. Geoffrey Noble advised the Committee that the pond behind the Community Center
is full of algae and white froth with blue areas on it, and appears to have been treated.
Mr. Bolick will follow up on this and report back to the Committee.
Mr.Noble added that St. Thomas and St. Maartin are considering using Blue tilapia, but
this lake is PBSD's. The Committee agreed that they would not allow Blue tilapia to be used,
and Mr. Dorrill would contact these communities immediately and advise them of this.
LAKE LOCATIONS RECEIVING AERATION & LITTORAL PLANTS
The lakes at Oakmont, L'Ambiance and Georgetown will be the first to have the aeration
and littoral plantings installed. Other lakes will follow. With no correlation between nutrient
loading and visible algae, the Committee discussed the effectiveness of algae control methods.
The lakes on the map indicated as private are not maintained by PBSD.
CONSIDERATION OF A LAKE NUMBERING SYSTEM
Mr. Cravens suggested a numbering system be developed to identify basins and lakes.
REEVALUATE PROS AND CONS OF ALGAE CONTROL USING BLUE TILAPIA
New information was provided regarding unintended consequences of using Blue tilapia
for algae control. Mr. Cravens suggested that the Blue tilapia program remain on hold until the
rainy season, at which point it can be reevaluated, and the Committee concurred.

Water Management Committee of the Pelican Bay Services Division
February 26,2015 Meeting Minutes
STATUS OF LAKE NUTRIENTS AND COPPER
Dr. Trecker reviewed the levels of nutrients and copper in the lakes. Copper levels were
trending downward indicating equilibrium. Continued monitoring was recommended.
Mr. Dawson motioned, Mr. Bachman seconded that a recommendation be made to
the full Board that a copper testing site be set up in Lakes 2-1 and 3-lat the entry
sites where water from outside of Pelican Bay enters Pelican Bay. The motion
carried unanimously.
IRRIGATION ORDINANCE
The County is considering an ordinance that would make recycled water subject to the
same mandated restrictions as potable water. If approved, this could decrease the high nutrient
levels in the lakes as there would be less runoff.
UPDATE ON COMMUNITY EDUCATIONAL OUTREACH
The water quality brochure would be updated with a new picture and title"Our Lakes in
Pelican Bay", the water quality presentation would be revised and presented to key groups in the
community; and an article on the lakes would be submitted to the Pelican Bay Post.
COPPER REMEDIATION WITH GEOFFREY NOBLE
Mr. Geoffrey Noble presented his research on copper remediation that he has been
collaborating on with the Chemistry Department at Florida Gulf Coast University. Mr.Noble
proposed doing copper remediation work in one of the PBSD lakes at a cost of$20,000. The
Committee did not feel they could justify that amount of money at this point.
ALTERNATIVE TREATMENTS
Mr. Bolick has the peroxide treatment on order,which Mr. Dorrill indicated was
effective at the Lely Resort.
ADJOURNMENT
Mr. Bachman motioned,Mr. Streckenbein seconded to adjourn at 2:49 p.m. The
motion carried unanimously.
