I Mr. Andrew Cardinal, Sr. Sept. 11, 1992 Page Two INALYSI$ Policy 3-6 of the Council's Water Resources Management Development Guide/Policy Plan states that the Council will protect the utility of the region's water and related land resources and seek their restoration, where-needed. In this case, restoration of the drainageway is a better alternative than constructing a new darn and undertaking large-scale dredging for the following reasons: 1) There are no flood-storage benefits associated with re-creating the lake since it is located at the bottom of the watershed. 2) Only limited water quality benefits would be realized from the re-creation of the lake, because Long Lake is the primary sink for upstream sediments and nutrients, While Locke Lake has received sediment from the floodplain and streambanla in its subwatershed, this could be reduced by an aggressive program of streambank and streambed stabilization. Based on previous Council research, a comprehensive streambank erosion control program could cost the RCWD as little as $520,000. This is considerably lower than the $800,000 estimate for the initial dredging, and would provide a permanent solution to the erosion problem. Taking into account the limited water quantity and quality benefits associated with this project, along with the substantial costs, it seems prudent for the RCWD to not pursue this project. Instead, the Council suggests,the watershed district concentrate on a more aggressive streambed and bank stabilization program to reduce sedimentation in Rice Creek. If you have any questions or concerns about the issues discussed in this letter, please call Sheryl Corrigan of the Council's staff at 291-6572.
