Abstract: A mixing apparatus is disclosed for ponds and other shallow bodies of water. The apparatus uses air flow to entrain and move large volumes of water up and through the mixer. This movement of water creates a mixing of water from different depths within the body of water, and thus prevents, eliminates, or reduces stagnation of the water. The air flow is driven by one or more blowers, which may be mounted on the apparatus. The air from the blower is injected into the water about one to two feet below the surface. The air is injected through a series of relatively large holes positioned on opposed sides of tubing. The injected air creates water flow in sufficiently large volumes to mix the water within a shallow body of water of moderate size.
