2011 Map of Porters Flat

About this map

The Snake River defines the western edge of this landscape on the Oregon-Idaho border, where the historic crossing at Porters Ferry once connected the high desert plains. This 2011 survey reveals an intricate network of water management essential to life in Malheur County, featuring the Galloway Canal, Smith-Hemenway Lateral, and Domby Ditch. These irrigation features support the agricultural settlements of Eaton, Jonathan, and the namesake Porters Flat. To the north, the terrain rises sharply toward Kelly Mountain and Haystack, contrasting with the level expanses of West Weiser Flat. Local transport is anchored by Olds Ferry Rd, following the river's course past Porters Island. The map documents a rural corridor where family-named roads like Pringle Rd and Ferrel Rd link isolated homesteads to the vital water sources of Scott Creek and Warm Springs Creek.
