Our Watershed is an incredible resource left to us by the City forefathers. Since 1917, when the City began to have a controllable water source, the watershed has provided clear, plentiful water for the citizens of Forest Grove. Publicly owned, the 4,225-acre forested watershed constitutes a significant ecological, economic, and social resource for the community of Forest Grove and the region.

Watershed Management Plan

The City closely follows the Watershed Management Plan (PDF) to keep a sound, balanced environment for wildlife to flourish, while protecting water quality. The Watershed Management Plan classifies forest management goals and related issues, determines the most important management policies for resolving issues and achieving goals, and identifies a list of recommended actions.


Public tours are hosted annually, typically during the summer. If you are interested in attending a tour, please call the Engineering office at 503-992-3228 to inquire about the next scheduled tour date.
