Page 35 <br /> Page 2 <br /> The water quality on Lake Minnetonka made a dramatic improvement <br /> as the effluent from the 'sewage treatment plants was removed from <br /> the Watershed; however , continued urbanization of the Watershed <br /> has increased the quantities of nutrients contained in the run-off, <br /> which in part has negated some of the benefits from the removal <br /> of the sewage effluent from the Watershed. It is our belief that <br /> water quality on Lake Minnetonka is no longer improving but rather <br /> becoming more polluted. <br /> The Harza Study was an excellent technical study of Lake Minnetonka, <br /> establishing many benchmarks of water quality that existed in 1968 . <br /> It isolated for us the chief cause of pollution to Lake Minnetonka <br /> and made recommendations to minimize this pollution effect. We <br /> believe that it is now time for the Harza Study to be updated by <br /> reevaluating present water quality trends and isolate the present <br /> sources of pollutants to Lake Minnetonka together with recommend- <br /> ations to minimize these causes. <br /> The Orono City Council requests that the Lake Minnetonka Conservation <br /> District in conjunction with Minnehaha Creek Watershed District <br /> enter into a joint project that will update the information contained <br /> in the Harza Study and make recommendations to preserve the quality <br /> of Lake Minnetonka for future generations. <br /> We feel that now is the time for us to update the technical <br /> information about Lake Minnetonka and reevaluate our goals and <br /> policies to insure that this great natural resource is preserved. <br /> Thank you for your cooperation in this matter. <br /> Yours truly, , , <br /> i <br /> C T OF ORON <br /> , G�� <br /> Brad Van Nest <br /> Mayor <br />
