Master This Comment Date Who Made Comment List # Tables # precipitation, groundwater, and internal loading from curly -leaf pondweed, wind mixing, rough fish activity, and sediment release. Loads from motorboat activity is also a likely phosphorus source but was not quantified. According to this information from the Barr study, "Loads from motorboat activity is also a likely phosphorus source but was not quantified." A significant amount of taxpayer money was spent on this study and it identified existing phosphorus loading sources, instead of spending additional money on sources not quantified the managing board should focus on the findings of the study. 351 91 Grass Lake WMO Watershed Management Plan — 6/201141 September 15, Jill Roberts 2011 The following monitoring and study recommendations were made: DOWater quality monitoring in Central Park East and West Wetlands and the Charlie Pond system. DOFisheries impact study on water quality (e.g. carp) DOSediment core collection and analysis in Central Park East and West Wetlands, the Charlie Pond system, and Bennett Lake. DOWater quality monitoring in the shallow portion of Lake Owasso The following structural BMP recommendation was made: DDlncorporation of infiltration BMPs throughout the watershed. The following in -lake BMP recommendation was made: DOCurly -leaf pondweed management The Barr study makes no recommendation about limiting boat traffic. 353 92 1.9.f To address internal loading (in Lake Owasso) work with member communities to test the impacts of establishing a no boating area or no wake zone on certain portions of September 15, Jill Roberts the lake (e.g. shallow areas) for a defined time period; the goal being to make it a permanent ordinance if the results are positive. 2011 354 93 Establishing a goal to make a permanent ordinance of no boating area or no -wake zone on Lake Owasso should not be a goal of the GLWMO. This would not be improving the September 15, Jill Roberts water quality while maintaining recreation. The Implementation Activity is not in keeping with the Watershed wide Goal 1.2 above. 2011 358 94 The Lake Owasso Management Plan (Osgood, 2000) set the following management goal for Lake Owasso: "maintain the high quality of Lake Owasso and provide recreational September 15, Jill Roberts use." To meet the goal, the management plan also set the following management objectives: "maintain high water clarity, prevent Eurasian water milfoil from becoming 2011 problematic, provide safe and pleasant recreational uses, find a solution for low lake levels, and coordinate lake management." The current 3rd generation draft plan does not apparently see the value in the Osgood management goal of providing recreational use by providing safe and pleasant recreational uses nor does the current plan provide for finding a solution for low lake levels. Instead it states that it wants to spend $6,000 to address modifying the outlet into Wabasso to lower water levels on Owasso and it also wants to reduce pleasant recreational uses by imposing no /wake, no /boating areas, which will affect the safety of individuals using the lake. 360 95 The Cedar Island Lake study on the Estimation of Internal Phosphorus Loading for Cedar Island Lake was completed by Freshwater Scientific Services, LLC in 2010. This report September 15, Jill Roberts also used the Yousef study referenced by Mr. Westerberg at the August 18, 2011 GLWMO board meeting. The Cedar Island Lake report responds to issues in a very similar way 2011 to the way the current GLWMO draft has proposed dealing with water quality issues on Lake Owasso. Cedar Island Lake is very different from Lake Owasso in size (87 Acres) and water depth (7 foot maximum). "In addition, it would be useful to conduct a small study on the effects of intense motorboat activity on sediment resuspension and phosphorus levels in the lake." (This is taken from the Final Remarks found on page 8 of the report.) 361 96 Given the amount of people who recreate in the GLWMO and existing issues related to water quality and conflicting uses of the resources, the main objective of the process September 15, Jill Roberts was to reach as many constituents as possible in an effort to solicit issues, needs and concerns reflective of the broad base of users. A detailed description of the GLWMO's 2011 efforts to reach a diverse audience during the watershed management planning process is described in Appendix D. Grass Lake WMO Watershed Management Plan- 6/2011108 It would have been beneficial to have had a stakeholders meeting during the comment period, after the draft had been released. I specifically refer to the Lake Owasso "test' of no -wake / no boating areas that lacked a referenced source for the inclusion in the draft plan.
