EAGLE SPRING LAKE MANAGEMENT DISTRICT: Eagle Spring Lake Sediment Impact Analysis

Purpose

Phase 1 - Sediment Impact Analysis. AUSACOE sediment study consisting of: a) Collection of 12 sediment cores. 6 cores will be analyzed for phosphorus (P) release from the marl layer and 6 cores will be analyzed for P release from the organic (i.e. peat) layer. 3 cores of each will be tested in oxic conditions and 3 cores of each will be tested in anozic conditions. b) Collection of 3 sediment cores to esdtimate compaction due to sediment dewatering. c) Collection of 9 sediment cores to estimate internal phosphorus loading in the surface marl layer as a result of sediment dewatering. A electronic version and paper copy of a report of A through C above and a separate report containing the following elements: 1) Long term water budget; 2) Analysis of the capacity of the two Eagle Spring Lake outlets(i.e.dams): 3) Mapping of potential lake bed to be exposed during a lake drawdown; and 4) Recommendations for extent of drawdown (depth, duration and rate).
