Queen Bee tests the capability of natural systems to remove phosphorous from the water.  Between the inflow and outflow points shown in the aerial photograph within is the wetland treatment area.  Water currently flows up this wetland from the inflow and back down it to the outflow point.  Measurements of phosphorous concentration are made at the inflow and outflow points to establish how much phosphorous is consumed by the sacrificial wetland ecosystem.  Removal of phosphorous from the Lake Okeechobee watershed is important because it prevents excessive nutrient load from entering Lake Okeechobee, Florida's largest source of fresh water.
