The motion carried unanimously. 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. 2 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. Tom Cravens, Chairman 4/21/2015 11:54:13 AM 3
