Water Rights

Q.
I'm purchasing or selling a piece of property. Do I have water rights?

A. All legally established water rights are on record with the Oregon Water Resources Department. You may contact our office for information on a specific piece of property or search our interactive water rights mapping application.

Q.
I just have a small lawn and a little garden. Do I need water rights to irrigate from my well?

A. Oregon law allows the irrigation of up to 1/2 acre lawn or non-commercial garden if the source is ground water. However, there may be restrictions on this use if your property is within a ground water management area, such as the Cooper-Bull Mountain Critical Ground Water Area. Please contact us to determine if your property is located in one of these special management areas.

Q.
I want to build a small pond on my property. Do I need a water right?

A. In most cases, yes, you would need to apply for a water right. Small, off-channel ponds can be applied for under an Alternate Review Process that is generally faster and less expensive than the standard reservoir application. To download application forms, please visit the Oregon Water Resources Department website.

Q.
I have a small creek/stream running through my property. Can I pump out of it to irrigate my lawn?

A. No, not without a valid water right issued by the Oregon Water Resources Department. The Tualatin Basin is closed for any additional surface water permits.
