The aquifer is centralized under Spokane Valley and the Rathdrum Prairie, hence the name; it contains ten trillion gallons (38 trillion liters) of water, and is part of the Columbia River drainage basin. The only watercourse that remains above the surface for an extended distance is the Spokane River. The area surrounding it receives an average of 15–30 inches (38–76 cm) of rain annually. The aquifer is the primary water source for the greater Spokane area, which is home to over 700,000 people in the Inland Empire.[2][3]
