History
Formed in 1874 from Douglas County, Grant County, Jackson County and Wasco County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Lake County was created on October 24, 1874, from Douglas, Grant, Jackson, and Wasco counties. On October 20, 1882, Lake County lost territory to the creation of Klamath County. In 1885, Lake County gained territory from Grant County, and in 1927, boundaries with Klamath County were redefined to run along range lines.

Roof outlines traced from aerial imagery from FEMA Response Geospatial Office with Oak Ridge National Laboratory (ORNL). Good for seeing what is on a lot; not accurate enough to set a fence from.
