Description
What is SAFE YIELD? Why is it important? How do we achieve it? In Arizona, safe yield refers to a long-term balance between the water that is naturally and artificially recharged to an aquifer and the groundwater that is pumped out. When more water is removed than is recharged, the aquifer is described as being out of safe yield. When the water level in the aquifer then drops, we are said to be mining groundwater. View a pdf.
