minutes as presented. The motion carried unanimously.
AUDIENCE COMMENTS
Mr. Ray O'Keefe, resident of the Breakwater Association, commented on the results of
alum treatment in the three lakes at the Breakwater resulting in a significant reduction of
phosphorus and nitrogen, and significantly improved water clarity.
Dr. Trecker expressed his concerns over future concentrations of alum in lake sediment.
STATUS OF AERATOR PURCHASE AND INSTALLATION
Mr. Bolick reported that the eight newly installed aerator systems became operational
today. The PBSD FY2017 budget contains $100,000 for installation of aerators in the remainder
of PBSD lakes which have no aerators.
CH2M HILL PROPOSAL FOR NON-STOICHIOMETRIC ALUM TREATMENT OF
PONDS TO REDUCE PHOSPHORUS
A consultant from CH2M Hill was unable to attend this meeting. Dr. Trecker will
schedule a presentation by CH2M Hill on non-stoichiometric alum lake treatment at the next
committee meeting.
STATUS OF TILAPIA, PEROXIDE,BACTERIA,AND HYDROTHOL INCLUDING
COST AND FREQUENCY OF USE
Mr. Cravens commented on the need to determine the cost effectiveness of each type of
lake treatment being used in PBSD lakes. Mr. Bolick's casual observation is that tilapia is the
most cost effective type of treatment.
Dr. Trecker commented that although upland lakes are not regulated, he reiterated the
importance of algae removal in these lakes which include concerns of(1) aesthetics, (2) sediment
buildup, and (3) consequences of the lake water feeding into Clam Bay.
Ms. O'Brien commented on the need to explore any possible adverse effects from tilapia
to Clam Bay. Dr. Trecker volunteered to study existing literature on negative consequences of
tilapia.
Mr. Bolick reported that he maintains and regularly updates a table of PB lakes with
corresponding treatments. He will provide a copy of this table to committee members.
PLANS FOR LAKE BANK REPAIRS
Mr. Dorrill reported that lake bank surveys will be completed by staff in the first quarter
of FY2017. The FY2017 budget for lake bank repairs is $75,000.
PLANS FOR STORMWATER DRAIN REPAIRS
Ms. Jacob reported that all of the stormwater drain repair requests reported to Collier
County Road& Bridge will be completed within the next three or four weeks.
