Oregon Water Resources Department – Watermaster, District 18
Formerly Washington County Watermaster Program
The District 18 Watermaster Office is no longer represented as a department within the Washington County Land-use and Transportation division.
You will continue to receive support related to water rights, surface water, groundwater, and water use concerns across Washington County.
This page outlines the changes, provides updated contact information, and directs you to essential resources.
What's Changing?
The Watermaster program is now solely managed by the Oregon Water Resources Department (OWRD).
- New email: [email protected]
- New phone number: 503‑602‑0513
- Contact information and regional support details can now be found through OWRD’s directory.
What’s Staying the Same?
- Local Watermaster services continue without interruption.
- Support for water rights questions, enforcement, monitoring, and complaint investigations.
- Groundwater and surface water information remain available on the same dedicated pages you’re familiar with.
