years ago. Mr. Ferrington volunteered to show the Board that video at a future meeting, allowing for further discussion. Member Von De Linde questioned if this was something that could be repaired. Mr. Ferrington opined that, with the Rice Street interchange project scheduled in the immediate future, and the reconfiguration of 1 -694, opportunities may be available to correct the situation by increasing the culvert capacity to make it less likely to backflow in the future during moderate or heavy rain events. Chair Eckman asked if Mr. Ferrington would be willing to provide the video online. Mr. Ferrington advised that he could do so, but would prefer a presentation format to allow his verbal input on what the video contained. Action item: Chair Eckman asked that Mr. Ferrington provide his comments on expanding the Rice Street interchange culverts as part of his written comments for the Third Generation Plan, allowing the GLWMO Board to further address it through the Plan. Mr. Petersen sought clarification if the problem culvert was the one under 1 -694 or the one under the frontage road (Soo Street or any other restriction between the outlet channel and grass lake), noting that there was a culvert under County Road E /Soo Street. He also questioned whether there had been evidence of flows over this road in the past. Mr. Ferrington opined that it was at the intersection, and was covered over and proceeded north underground. Jill Roberts, Lake Owasso Resident In her career as an educator, and having been a resident of Lake Owasso during the 1940's to -date, Ms. Roberts advised that she could attest to the improved quality of the Lake for recreational purposes than was available during the early 1950's and throughout the 1960's. Ms. Roberts opined that a lot of that improvement was due to weed treatment programs and opening the Lake to allow for boating. Ms. Roberts expressed her concern, as well as concerns of other Lake Owasso residents, with suggestions in the DRAFT Third Generation Plan related to "no wake" or "no boat" zones being implemented. Ms. Roberts requested the source and intent of this suggestion; and why it was included in the Draft Third Generation Plan. In the interest of time and to avoid redundancy, Chair Eckman asked that Ms. Roberts put her specific questions /comments in written form to receive a formal response from the GLWMO. Ms. Roberts advised that she intended to provide written comment to that effect; however, she requested preliminary information at this time. In response to Ms. Roberts' concerns, Member Westerberg provided a summary of recommendations from one of the available studies related to wakes and motorized boats on lake water quality. Mr. Westerberg read the summary and recommendations based on a 1979 study entitled, "Changes in Phosphorus Concentrations due to Mixing by Motorboats in Shallow Lakes," authored by Yousef A. Yousef at the University of Central Florida and dated November, 1979. Ms. Roberts sought additional information on whether the entire study was based on three specific lakes in Florida and whether it was a long -term study. 11
