About this map

The Owyhee Dam and the northern tip of Lake Owyhee anchor this 2017 survey of Malheur County, Oregon. The landscape is defined by the complex water engineering required for high-desert agriculture, tracing the intricate paths of the Owyhee Siphon, Snively Siphon, and Kingman Lateral. These irrigation features, along with several tunnels such as Tunnel Number 1 and Tunnel Number 5, reflect the heavy industrial intervention in the canyon topography.

Beyond the infrastructure of the Owyhee River, the map identifies notable natural landmarks and geothermal features including Snively Hot Spring and a standalone Hot Spring to the northeast. Distinctive geological formations like Balancing Rock, Pinnacle Point, and Blackjack Butte punctuate the terrain, while numerous upland water sources like Four Points Reservoir and Mahogany Long Draw Reservoir highlight the managed hydrology of the region.
