TMDL Study Update and Sampling Stations Update Mr. Petersen advised that three (3) sampling stations were installed on August 4; and provided their approximate locations without being too specific to avoid potential vandalism of the stations. Mr. Petersen advised that the FOR bid included measuring six (6) storm events, two (2) per month; to determine the total phosphorus , total suspended solids, flow rates and volumes for larger events not less than 1/2 inch of rainfall. At the request of Chair Eckman, Mr. Petersen confirmed that the laboratory costs were inclusive in the bids; and advised that he had helped with their installation. At the request of Mr. Ferrington, Mr. Petersen clarified that the principal intent of the monitoring was not to better define input into Bennett Lake; but to provide sampling input for non - treated sub watersheds that would be used to calibrate the TMDL model. Mr. Petersen noted that the original Barr UAA monitored flow from the Galtier Street system at Lady Slipper Park. Due to current high water, however, they were unable to monitor at the original monitoring point and are now monitoring upstream of the original monitoring point. Third Generation Watershed Planning Update Special Meeting August 25, 2011 After a brief discussion as to whether it was still needed, the consensus was that the special meeting originally scheduled was no longer needed; and several Members advised that they would be out of town as well. Motion 11 -08 -10 Member Miller moved, and Member Von De Linde seconded cancellation of the previously scheduled Special GLWMO Board meeting of August 25, 2011. Ayes: 4 Nays: 0 Motion carried. Chair Eckman reviewed written comments received to -date on the draft Third Generation Plan regarding Restricting "wakes" and lake water quality (how should this issue be addressed in the Third Generation Plan? With one exception, they were all about the notation for further consideration of "restricting wakes" to address water quality. Chair Eckman expressed her dismay that this one notation had been blown so out of proportion; and that the other portions of the plan were not given fair consideration or receiving comment. Chair Eckman reiterated the intent of that notation in the Draft Third Generation Plan for further research related to motorized activity on lakes and impacts of that turbulence on phosphorus release; clarifying that it was not the absolute intent of that the Third Generation .Plan to expand no wake zones on Lake Owasso. Based on this misconception, Chair Eckman requested comment from individual Board members on their thinking of that one notation receiving so much attention; and whether it indicated an opportunity for additional education. Chair Eckman personally opined that she was more focused on addressing runoff into the GLWMO lakes prior to considering no wake zones expansion as a management strategy, especially without the apparent benefit of additional research and more scientific studies and methodologies for all the variables involved in the impact of motorized recreation on shallow lakes.
