Lake Lansing prior to dredging was eutrophic, had a surface area of 182 hectares (approximately 450 acres), a maximum depth of 11 meters (35 feet), and a mean depth of somewhere between 2.1 to 2.3 meters (7.0 to 7.5 feet). Surface area and maximum depth remained the same after dredging as before, but the mean depth increased to 2.7 meters (9.0 feet). Comparison of pre- and post-dredging data reveals an increase in transparency and substantial reductions in in-lake phosphorus and chlorophyll a. Trophic status of Lake Lansing improved from a highly eutrophic condition to a meso-eutrophic condition. Heavy metals, specifically arsenic and mercury, were not remobilized during dredging.
