The Sucker Lake to Snail Lake option <br />(Alternative 1) is recommended because of <br />its lower initial cost (excepting Alternative <br />3A), limited street restoration required, the <br />ability to combine this improvement with <br />existing City roadway improvement <br />projects, and because this option provides <br />the highest quality of water to Snail Lake <br />of any of the other options considered. <br />2. dater should be pumped continuously <br />into Snail Lake just after ice-out until the <br />lake reaches an elevation of 882.7 (esti- <br />mated pumping time -two months). <br />3. bVater should be pumped into the lake any <br />time the lake level drops below the mini- <br />mum management level of 881.5, until the <br />lake is raised to an elevation of 882.0 (sub- <br />ject to volume restrictions per agreement <br />with I~NIZ and SPV1~1). <br />4. Pdatural fluctuation above 881.5 should. be <br />allowed without intervention. <br />5. A high level outlet for Snail Lake, at eleva- <br />tion 884.0, should be constructed as part of <br />proposed roadway improvements to Snail <br />Lake boulevard. <br />6. If necessary, the take should be pumped <br />up to 882.7 before freeze-up to prevent <br />pumping large volumes of water the fot- <br />lowing spring to makeup for winter seep- <br />age losses. <br />7. All necessary reviews, approvals and per- <br />mits be obtained prior to proceeding with <br />construction. <br />Shnraview Minnesota Page 3 <br />
