Henry Hagg Lake (also Hagg Lake) is an artificial lake in northwest Oregon, in the United States. The reservoir is an impoundment of Scoggins Creek, which drains a small portion of the eastern side of the Northern Oregon Coast Range.[3] The lake and creek are part of the Tualatin River’s watershed in the Tualatin Valley.[4] It is located about 5 miles (8.0 km) southwest of Forest Grove.


Population growth, fueled by the success of Washington County’s local agriculture, increased the need for both residential and irrigation water. To satisfy this need, Henry Hagg Lake was created in 1974 behind an earthfill dam on Scoggins Creek. The reservoir was named in honor of Henry Hagg, an Oregon dairy farmer who was active in local agricultural committees during the first half of the twentieth century.
