U � r <br />.r <br />2315 Old Beach Road <br />Wayzata, MN 55391 <br />May 17, 1978 <br />EXH/,(3/T F <br />.dLS4t. p/3 <br />Mr. Earl Sween <br />2440 Old Beach Road <br />Wayzata, MN 55391 <br />Dear Mr. Sween: <br />I have read over the proposed dredging plan offered by WAWAPADCO <br />and I find that it is much better than the plan offered by <br />Mr. Novak. The retaining of water so'that the wetland only has <br />to deal with the nutrients from approximately 15% makes this plan <br />more appealing. <br />I visualize our role as follows: <br />(a) We can retain the effluent water from the dredge in the <br />Institute wetlands by sealing off the culvert which goes <br />under Old Beach Road. <br />(bJ We 'shall conduct daily determinations of the nitrogen, <br />phosphorus and dissolved organic carbon in the wetlaad until <br />concentrations are identical to Lafayette Bay water. At this <br />point we shall allow Mie water to return to Lafayette Bay. <br />(c) Fiske-Subba=ow, and Micro Rj eldahl methods will be used for <br />phosphorus and nitrogen determinations respectively. '- <br />(d) -We shall measure turbidity by spectrophotometry. <br />(e) We expect the West Lafayette Bay Association to pay for liming' <br />and landscaping the spoils area. <br />(f) ,The Freshwater Biological Research Foundation, has agreed. to <br />fund the project up . to the level of $5,000. <br />urs sincerely, <br />A A -A <br />M.
