Lake Eola Lake Restoration Methods C.W. SHEFFIELD, Pollution Control Officer TERRY L. STODDART, Microbiologist RICHARD ALT, Chemist RAYMOND T. KALEEL, Biologist Orange County Pollution Control Department Orlando, Florida 32806 MARTIN WANIELISTA, Director Environmental Systems Engineering Institute Florida Technological University Orlando, Florida 32816 INTRODUCTION The problems associated with pollution of lakes from industrial, municipal, and other waste sources are numberous. The restoration of these polluted waters is complicated and in most instances expensive. The project endeavors to demonstrate means for restoring lakes which have been degraded, following the elimination of pollutional sources. The restoration of Lake Eola in Orlando, Florida was the objective of the project. This lake was in a highly degraded state from various sources of pollutants. The restoration project consisted of initial research studies to determine the existing problems and.the development of a restoration plan. The basic plan consisted of the following: 1) lowering of the lake to enhance bottom material consolidation; 2) silt and muck removal; 3) adding layers of sand to help eliminate nutrient recycling; 4) treatment devices enacted on all storm drains; 5) algae control; 6) transplanting of macrophytes and; 7) restocking the lake with fish. Documentation of each phase was enacted by Orange County Pollution Control Department, Florida Technological University and other water pollution control agencies. T his project will serve as a model for other lakes to demonstrate an economical and practical means of restoring a polluted body of water. DISCUSSION GENERAL The restoration of Lake Eola was initiated by the action of many concerned Orange County citizens and governmental agencies. Lake Eola is located in the heart of the metropolitan Orlando area. This twenty-eight acre lake is surrounded by a beautifully landscaped park. It receives the surface run-off from four hundred acres of city streets. The storm water enters the lake via twenty-two active street drains. Several of these drains are continuously flowing, carrying waste water primarily from commerical cooling systems. The fountain located near the center of the lake recycles approximately 4.3 million gallons of water per day enhancing oxygenation of the lake waters. The morphology of the lake is given in Figure 1 and 2. The shoreline of the lake is fairly regular with no coves or sheltered areas. Two striking features of the shoreline were a seawall around the perimeter of the lake, eliminating natural beach areas, and a complete absence of submergent and emergent aquatic macrophytes. 401
