Prior Lake, MN 55372 July 16, 1992 Mr. John Stine, Regional Hydrologist Minnesota Department of Natural Resources 1200 Warner Road St. Paul, MN 55106 Dear Mr. Stine: Recently in our telephone conversations, you have indicated the need for the Board of Managers to submit a letter concerning the proposal to temporarily retain water in Spring Lake, Scott County. The Board proposes to use either sand bags or two 6-inch by 6-inch beams to be placed at the top of the sill of the outlet to Spring Lake. This will raise the outlet elevation of Spring Lake temporarily to an elevation of 911.0:t. This would retain an approximately 1 foot of water over what is normally the elevation of Spring Lake. The purpose of retaining this water is the above normal precipitation and rising water levels in the watershed of Prior/Spring Lake. The 509 Plan states that one of the main goals of the District is to retain as much water in the watershed as possible. The Board feels this is one way to retain a substantial amount of water. Current water levels on the lakes outletting to Spring Lake indicate that if all water is released to Prior Lake with no water discharged, the water surface elevation of Prior Lake will reach an elevation of 903.6:t. The current water surface elevation of Prior Lake as of July 13, 1992 is 902.74 and rising. Damage has occurred to the shoreline as a result of less than standard shoreline protection measures and rising lake levels. " Currently, the flow out of Spring Lake is such that the maximum outlet capacity of the Prior Lake outlet would be such that it would only be half of the flow that is entering the lake. By damming Srping Lake to an elevation I-foot higher, the inflow to Prior Lake would be approximately equal to the outflow from Prior Lake. In this manner, the lake level could be maintained at its current elevation while minimizing the outflow from Prior Lake. As the elevation in Prior Lake begins to drop, the elevation in Spring Lake will also be lowered. Raising the outlet of Spring Lake could accomplish several things. The District '.0( I II I i' , I I' I' I J Mr. John Stine -2- July 16, 1992 could reduce the severity of the peak on Prior Lake. It would also reduce the need for greater discharges from the outlet, thus allowing more water out of the District. Levels on Spring Lake have peaked at elevations greater than the proposed elevation. The District recognizes the need for a meeting with County authorities to ascertain the impacts of this proposal and a Board Manager will be contacting you shortly after the anticipated arrival of this letter to arrange such a meeting. If you have any questions, please feel free to can Bill Dilks (447-4166) or me (473-4224). " Sincerely, JAMES M. MONTGOMERY, ~U~NGINEERS. INC. Peter R.
