Water Quality - Marys River Watershed Council

The City of Corvallis Public Works and the City of Philomath Public Works both draw water from the Marys River in order to service both municipal areas. Learn more about where your drinking water comes from: the City of Corvallis Water Quality Reports and the City of Philomath Annual Water Quality Reports.

About 1/3 of Corvallis’s drinking water and all of Philomath’s water supply comes from the Marys River and its tributaries.
