APPROVAL OF 01/19/16 MEETING MINUTES
Mr. Streckenbein motioned, Mr. Dawson seconded to approve the 01/19/16 meeting
minutes as amended. The motion carried unanimously.
AUDIENCE COMMENTS
Ms. O'Brien provided four photos of littoral plants in the pond north of the Naples
Grande.
COMMENTS ABOUT TECHNIQUES USED TO COMBAT ALGAE IN PELICAN BAY
Mr. Cravens gave a synopsis of techniques used to combat algae in Pelican Bay since
August 2012, when the use of copper sulfate throughout Pelican Bay ended. The PBSD has
obtained good results by installing aerators and littoral plants, although additional chemicals are
required for touch up. The PBSD has achieved good results with blue tilapia, although the
tilapia's life span in Pelican Bay lakes is still unknown. Dr. Trecker is looking into bacterial
treatment which is known to reduce sediment. Mr. Bolick reported that littoral plants will be
installed shortly in 26 lakes.
STATUS/PLANS FOR INSTALLING AERATORS IN 2017
Dr. Trecker reported that the agenda item should have been for a status of 2016, not
2017. Mr. Bolick reported that we have $100,000 in the FY16 budget for installation of
approximately 10 or 12 solar aerators. Once sites have been finalized,he will notify the
respective homeowners' associations and/or PBF.
CURRENT READINGS ON EFFECTIVENESS OF TILAPIA,BACTERIA AND
PEROXIDE IN LAKE TRIALS
Mr. Bolick reported no algae in the 2 test lakes with tilapia. He reported that peroxide
has shown to be effective in combination with a chemical herbicide. Mr. Bolick reported that the
results from the six month bacteria lake trials (begun in January 2016)will not be available until
July. Mr. Cravens suggested the exploration of mechanical algae removal.
STATUS ON SEDIMENT TESTING
Ms. Jacob reported plans to begin sediment testing by the Collier County approved
sediment tester in mid-March, with a cost of approximately$10,000. Copper levels will be
compared to 2013 test results. A motion on this item was made and approved after the meeting
was closed and when the committee reconvened.
STATUS/PLANS FOR LAKE BANK EROSION PROJECTS
Mr. Dorrill reported on plans to re-survey six or seven lakes with severe lake bank
erosion. Mr. Cravens reported on the 5000 feet of erosion on the west side of the north berm.
$75,000 has been budgeted in FY16 for lake bank erosion projects. Mr. Dorrill will provide the
lake bank survey results at the April PBSD Board meeting. At that time, decisions can be made
on which projects to complete in FY16.
LAKE WATER QUALITY DATA
Dr. Trecker provided a handout which listed the Pelican Bay lakes with high levels of
phosphorus (.30 mg/L or higher) and copper (90 µg/L or higher) for each quarter of 2015, which

was added to the record. All lakes listed were either golf course lakes or private lakes. Dr.
Trecker commented on the high levels of copper in some lakes, despite the fact that copper is no
longer being used to treat any Pelican Bay lakes. He also commented on the high level of
phosphorus in the Vizcaya lake which feeds into Upper Clam Bay; this may be the cause of the
high level of phosphorus in that bay. Dr. Trecker has shared these results with the respective
association presidents or representatives of these private lakes.
ADJOURNMENT
IThe meeting was adjourned at 2:35 p.m.
THE COMMITTEE RECONVENED AT 2:37 P.M. TO VOTE ON THE MOTION FOR
AGENDA ITEM#8
Dr. Trecker motioned, Mr. Streckenbein seconded to recommend to the full PBSD
Board that we undertake sediment testing in ten lakes in accordance with the
protocols used in 2013. The motion carried unanimously.
