This article begins with a discussion of thermal stratification of impounded waters, the disadvantages of stratification, and several attempts at using compressed air to mix a reservoir. Several examples are provided of the use of aerohydraulic guns, or bubble guns, which shoot air bubbles to the surface from underwater tubes. An example of direct aeration at Lake Bret, Switzerland, is mentioned, along with the use of submerged wiers on the Roanoke River in Virginia. Various other methods are mentioned such as bunger valves that have been used in some dams to control the discharge and provide aeration of low oxygen hypolimnion waters.
