ABSTRACT:
Circulation systems for ponds, lakes, or other bodies of water. In one set of embodiments, water is drawn up from the depths of the body for exposure to the atmosphere and to generate an overall, high flow circulation pattern throughout the entire body. In other embodiments, the circulation in the body of water is primarily limited to an upper aerobic zone with only small and controlled volumes from a lower anaerobic zone being brought up. Each system preferably includes a flotation platform, dish, impeller, and draft tube with specific modifications to the various systems to adapt them for use in a variety of environments.
