(2) When the Willamette River serves as the boundary between Linn and Lane Counties in subsection (1) of this section, a reference to the river refers to the middle of the Willamette River as it existed on January 8, 2003, and may be further identified using coordinates and other location information determined by the affected county surveyors and filed by the appropriate counties with the appropriate county assessors and the Department of Revenue under ORS 308.225. [Amended by 2003 c.622 §2]

Note: In addition to the boundary described in 201.200, the eastern boundary of Lane County is the summit of the Cascade Range adjacent to parts of the western boundaries of Deschutes County (see 201.090) and Klamath County (see 201.180). The northern boundary of Lane County is the southern boundaries of Linn (see 201.220), Benton (see 201.020), and Lincoln (see 201.210) Counties. The western boundary of Lane County is the Pacific Ocean.

Umpqua County, referred to in 201.200 (1), was incorporated in Douglas County in 1863.
