It was interesting to note that the results obtained from Lake Mizell were not as conclusive because it was frequently used for recreational activities which made it difficult to maintain a valid control. This suggests that while the GLWMO proposes to conduct a "test ", on this very real recreational lake, Lake Owasso, it would need very large areas of no boat traffic to maintain a valid control. 335 85 Carp also have been earmarked as stirring up the sediment in the lake bed. Carp have been a very real factor in the waters of Lake Owasso for many years. The carp are an September 15, Jill Roberts issue and the plan should address their removal. 2011 340 86 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 341 87 I am opposed to the test of a Lake Owasso no /wake, no /boat areas. This "test' carries with it heavy ramifications, a few include: September 15, Jill Roberts Safety, in concentrating boat traffic in a smaller area of the lake. 2011 A decrease in property values of home owners on the lake. Minnesota has many boating enthusiasts that value boating and recreation on Minnesota lakes and have invested a great deal of money in purchasing equipment that could not be used. The goal of maintaining the lake for recreational pleasure is stated in the GLWMO document. Implementing this "test' results in negating recreational lake pleasure for many individuals and should be removed from this draft plan. Implementing a "specific monitoring activity: Develop and implement an investigation to better assess the magnitude of the impact of motorized watercraft activities on phosphorus loads to the system, by monitoring water quality on days of high use." (21.1b, page 128) This appears subjective and needs better clarification. 345 88 I am against spending $2500 to evaluate establishing a no boating area or no -wake zone portions of Lake Owasso. This proposal is in conflict with the page 9 Executive September 15, Jill Roberts Summary paragraph that states, "Recreation is a key reason the residents of GLWMO are interested in the local lakes, ponds, and wetlands." 2011 346 89 GLWMO Executive Summary 1 18 September 15, Jill Roberts SNAIL LAKE 2011 Recreational Uses: Fishing, boating, swimming Should other sports including waterskiing, wakeboarding, knee boarding, or tubing be included in this use statement? GLWMO Executive Summary 20 BENNETT LAKE Recreational Uses: Fishing, canoeing GLWMO Executive Summary 21 Issue Summary: Bennett Lake, which is located in the City of Roseville's Central Park, has poor water quality and is listed as impaired by the state, due to excessive nutrients. Lake Bennett has neither boat activity nor water sport and yet is cited for poor water quality. This Lake drains into Owasso. 350 90 Grass Lake WMO Watershed Management Plan — 6/201140 September 15, Jill Roberts The Lake Owasso Use Attainability Analysis (Barr, 2009) is a lake management plan that includes a diagnostic study that assesses the water quality of the lake, identifies water 2011 quality issues, and recommends structural, non - structural, and in -lake practices to achieve water quality improvement. A watershed model (using the software P8) was developed to evaluate the phosphorus loads generated in the watershed. The following are the main conclusions of the study: DDAnnual water and phosphorus budgets were developed, based on monitoring from 2007 and 2008, that identified the following phosphorus sources to the lake: watershed runoff, internal loading from ponds and wetlands within the watershed, direct Grass Lake Watershed Management Organization — 2011 Watershed Management Plan Response to Comments: 60 -dav review period 9/19/2011 Page 13
