ORS § 552.310
The right to condemn property, pursuant to ORS 552.305(4), shall include property already devoted to public use, including city, state and county property, which is less necessary than the use for which it is required by the district. In the acquisition of property or rights by condemnation, the board shall proceed in the name of the district under the provisions of the laws of Oregon. However, the right of condemnation may not be exercised against any water right; against land or other property owned by a city supplying domestic water; a public utility as defined by ORS 757.005; against a telecommunications carrier as defined in ORS 133.721; against lands of a domestic water supply district organized under ORS chapter 264, an irrigation district organized under ORS chapter 545, a drainage district organized under ORS chapter 547, a diking district organized under ORS chapter 551 or a corporation for the use and control of water organized under ORS chapter 554; or against property of the State of Oregon for highway purposes.
