McMinnville Water & Light serves approximately 12,500 water customers through a gravity-fed water system that begins with a 6,350-acre watershed located in the Coast Range. Water is stored in McGuire and Haskins Reservoirs, which have a combined capacity of 3.5 billion gallons. The water from those reservoirs flows through the water treatment plant and water transmission/distribution system to supply the City of McMinnville with an abundant source of high-quality, low-cost drinking water.
