CITY OF SPARTA: Perch Lake Rehabilitation Planning Study

1. Perform a detailed survey of the bottom of Perch Lake, consisting of cross sections every 100 feet from the dam to the upper end. 2. Perform a survey of selected areas designated as spoil disposal areas including estimating the area and depth of spoil spreading required to dispose of materials determined to be taken from lake bottom. 3. Create a lake bottom map showing cross sections of the present lake bottom and the proposed lake bottom to determine the sediment volume to be removed. 4. Develop a report that includes a description of the watershed, the lake conditions, the sedimentation history, and an estimate of the future sediment loads from the watershed. 5. Prepare a final report.
