Boa 66 , <br /> Cr}�stal Bay, r� 55323 <br /> Dear I•1r'. Olson: <br /> Last summer scientists at the Gray Freshwater Biological Institute <br /> surveyed each lake basin of Lake 2�finnetonka. Stubbs Bay was shown <br /> to be the nost eutrophic bay in terms of turbidity, algal bloom, <br /> and nutrient content. In fact, it �oas c,�orse than Aalstead's Bay <br /> � '. on the upper lake. Since Stub_tZS Bay is small and very shallow, it <br /> is clear that a multiple dock for large power boats would make <br /> the situation worse in several respects: <br /> • 1) The movement of sediments in shallow areas will cause <br /> increased nutrient �,�ash-out from the sediments into <br /> the lake. � <br /> 2) The adjacent shoreline properties will be sealed in by <br /> a sediment bank causing stagnation especailly on the shore- <br /> line southeast of the project and causing residents problems <br /> � with filamentous algae, aquatic macrophytes, and foul odors <br /> � from stagnation. Also; these residents k*ill have to dredge <br /> their wa}� out eventually if they wish access to the lake. <br /> . , . , <br /> If the dock is designed for low horsepower boats, then of course . <br /> the above detrimental factors would not apply. <br /> ' urs sincerely, . � ' <br /> �� <br /> J M.
