The retaining of water so that the wetland only has <br />to deal with the nutrients from approximately 15Z makes this plan <br />more appealing. <br />I visualize our role as follows: <br />(d) <br />(e) <br />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 />We shall conduct daily determinations of the nitrogen, <br />phosphorus and dissolved organic carbon in the wetland until <br />concentrations are identical to Lafayette Bay water. At this <br />point we shall.allow the water to return to Lafayette Bay. <br />Fiske-Subbarow and Mlcro—Kjeldahl methods will be used for <br />phosphorus and nitrogen determinations respectively. <br />We shall measure turbidity by spectrophotometry. <br />We expect the West Lafayette Bay Association to pay for liming <br />and landscaping the spoils area. <br />The Freshwater Biological Research Foundation has agreed to <br />fund the project up to the level of $5,000. <br />Yours sincerely. <br />M.
