Title

Phosphorous Dynamics of Lake Eola Sediments

Keywords

Lake Eola; Phosphorus; Sedimentation analysis; Phosphorus content in Water

Abstract

Lake Eola is an eutrophic, land-locked lake located in downtown Orlando, Florida. It has a surface area of approximately 27 acres (11 .0 Ha) and a maximum water depth of 22 feet (6.7 meters) near the center. Sediment samples were collected from the lake bottom at various water depths and analyzed for physical characteristics and phosphorus content. Lake water samples were collected and analyzed for selected parameters as related to sediment phosphorus dynamics. Phosphorus release from agitated, aerobic sediment samples was measured in laboratory batch experiments. Phosphorus release from anaerobic hypolimnetic sediments was measured by utilizing~ situ isolation chambers. Results indicate that phosphorus release from anaerobic Lake Eola sediments can be described by the Freundlich isotherm, indicating that release may be a desorption process. Phosphorus budget calculations indicate that the phosphorus that accumulates in the hypolimnion of Lake Eola has the potential for increasing productivity when overturn occurs.
