McGuire Reservoir

McGuire Reservoir is an impoundment of the upper Nestucca River in Yamhill County in the U.S. state of Oregon. It is the primary raw water source for McMinnville Water and Light, which supplies drinking water to the city of McMinnville.

Before a 21st-century project expanded the reservoir, it had a surface area of about 136 acre and a shoreline of about 4.8 mi. The expansion increased the holding capacity of the reservoir from 3760 acre-ft to 9800 acre-ft.
