Lake John Hay is located six miles northwest of Salem, Indiana and is used for drinking water and tournament and recreational fishing. With an average depth of 14-15 feet, it is ideal for algae and plant growth. The persistent, recurring algae blooms was causing taste and odor problems, which led to frequent complaints.
FluenceTORNADO® Self-aspirating surface Aerators and submerged Diffused Air Systems helped to rejuvenate the Laguna Niguel fresh water reservoir in Southern California. The aerators removed the algae and odor problems naturally, and kept the oxygen content of the water high enough to support a profitable fishing industry.
