2020 Map of Owyhee

About this map

The Snake River carves a winding path along the Oregon-Idaho border, defining a landscape of complex irrigation and river islands near Nyssa. This map documents a dense network of water management features, including the Owyhee Ditch, Mitchell Butte Lateral, and Kingman Drain, which support the agricultural plateaus of Lincoln Bench and Nyssa Bench. Along the riverbanks, a series of named islands like Prati Island, Big Cottonwood Island, and the curiously named Silly Goat Island appear as the river system shifts and branches. Near the junction of the Owyhee River and the main channel, the settlement of Owyhee and the Owyhee Cem provide specific points of interest for genealogists tracing local families. The presence of Beet Dump Rd points to the area's deep-rooted sugar beet industry and the logistical infrastructure required to move crops from the benches to market.
