News from the September 5, 2012 chapter meeting

The Central Florida Lake Management Society (CFLMS) hosted a chapter meeting on September 5th, 2012 at the Faculty Club on the Rollins College campus.  The central theme of the meeting focused on careers and opportunities in aquatic resources management and was geared toward engaging young scientists and engineers.  In addition to captivating the attention of the students and young professionals in the audience, the speakers also did an excellent job providing relevant discussion geared toward the many seasoned professionals in attendance.  Throughout the meeting, emphasis was placed on the importance of interaction and sharing of ideas which occurs primarily by participation in professional societies such as CFLMS and the Florida Lake Management Society (FLMS).

CFLMS president, Sergio Duarte, opened the meeting, introduced the theme and pointed out the necessity of engaging students and the next generation of lake management professionals.  Rick Baird provided the first presentation and gave a detailed and colorful account of his educational and professional experiences in Orange County.  Along with a photo documentary, Rick provided a great overview of the history of the Florida Lake Management Society and the opportunities Florida provides for development within the water resources profession.  Rick talked about the importance of citizen involvement and use of self-imposed Municipal Service Taxing Units (MSTUs) to generate funds for implementing water resources projects.

Tim Egan and Amy Giannotti provided an overview of the City of Winter Park lakes management program and some of the challenges and successes they have faced over the years.  Marissa Williams discussed the stormwater and lakes management program in the City of Maitland and how a stormwater utility fee has allowed the City to implement many projects that would not have been possible otherwise.  Dr. Jim Griffin concluded the meeting with a discussion on Water Atlas use, its advantages, and the ability to convey a wealth of water resources data with a modest investment that can benefit citizens and taxpayers around the State.  In addition, Dr. Griffin offered some tips on fishing in Lake Virginia (where he grew up).

The meeting was attended by nearly fifty members and guests.  More than ten percent were students so the meeting theme will hopefully resonate and encourage more student and young professional interest in the future.  The meeting was held over lunch, so there was plenty of opportunity for networking and meeting new people.  Many thanks to our host Ann Francis of Rollins College Environmental Sciences Department and to our sponsors AMEC and Environmental Research & Design, Inc.

News from the November 4, 2010 chapter meeting

The central FLMS chapter meeting was held at the City of Casselberry.  This meeting brought lake managers together with engineers for a great discussion.  Following an overview presentation of the planning and construction by Kelly Brock, the group was given a tour of the City's stormwater/recreational facility. As part of Casselberry's revitalization of the downtown area, a portion of the municipal complex located along Lake Concord was transformed from an office building with an adjacent, poorly performing stormwater pond into a functioning stormwater treatment site that now serves as a center for recreational activities. New recreational elements include a play structure, café area, interactive water feature, boardwalk, and amphitheater. An exfiltration trench and nutrient separation baffle boxes were installed to help protect Lake Concord from pollutants in stormwater runoff. The Park incorporates environmentally friendly materials and informational kiosks to educate the public on stormwater practices. The combination of these features creates an aesthetically pleasing park that is also extremely functional.

After the tour, Ron Novy and Sergio Duarte of Orange County Environmental Protection Division shared the results of the Lake Tibet sub-basin study.  To view the executive summary of this study, click here.  

Dr. Harvey Harper presented the following summary of the Lake Tibet Sub-basin 1 and 2 Study during our Butler Chain of Lakes Advisory Board Meeting on July 19, 2010: 

  • The study indicated that the average nutrient discharges from sub-basin 1 and 2 are 10 higher that the nutrient concentrations found in the lake and that the total phosphorus (TP) concentrations in the reclaimed water (RW) at the Bay Hill Golf Course were 100 times greater than the average phosphorous concentrations seen at Lake Tibet (1,558 vs. 14 micro gram / liter of TP).
  • Phosphorus loadings from the golf course area were found approximately 1,478% greater than phosphorus loadings onto the golf course area from residential areas.
  • The stable isotope analysis concluded that the majority of nutrients originated from organic sources. RW is typically categorized as organic in origin, while turf fertilizers are typically from inorganic sources.
  • Concentrations of both soluble and TP were substantially higher beneath golf course areas than in more upland portions of the two sub-basin areas.
  • The vast majority of phosphorus present in groundwater appears to be in the form of soluble phosphorous which is readily available for biological uptake by algae and plants and detrimental to the water quality of the lakes.

In addition to the reclaimed discussion above, an update on the status of the NPDES Pesticide General Permit requirements was discussed. The results of a recent public meeting with FDEP, F&W and FDACS reviewing the details of proposed permit program that the State of Florida was submitting to USEPA. In the proposal only a select group of agencies need to submit “Notice of Intents” for pesticide applications. All local governments and private applicators are covered under the State’s approved permit and NOIs would not be needed. Click here for the Draft Proposed rule.

A short update on recent projects wa also held. Orange County and Seminole County discussed the results of projects to re-vegetate stormwater pond areas with native species. It was concluded that the first year required heavy maintenance but once established, the native species began to take a foothold against invasive. Continued monitoring was needed before a final conclusion could be developed.

Orange County discussed a new project to incorporate several “next generation” technologies into a nutrient reduction project. A Stormwater Reuse/Harvesting pond with a Solar Irrigation component was mentioned as a current project being planned for the Barnett Park at Lake Lawne. The project would not only provide treatment in meeting the lakes TMDL reductions, but also be an alternatively powered source of irrigation water that would reduce the Parks use of potable water. The pond itself includes a triple treatment cell design that includes a cell for trash/floatable removals, sediment settling and water storage. 

It was also noted that the bringing together of the engineers from ASCE and the scientists/biologists from CFLMS was something that was long overdo and continued events should be planned in the future

This is a great opportunity to share information and keep up with the latest lake management issues throughout the year with your Central Florida colleagues.
