About this map

The Owyhee River carves a deep path through Malheur County, anchored by the massive water management infrastructure that defines this landscape. This 2024 survey captures the intricate network of water transport systems including the Owyhee Siphon, Snively Siphon, and Black Willow Siphon, which serve the high desert agricultural interests via the South Canal and Kingman Lateral.

Remote reservoirs and springs are scattered throughout the hills, including Mahogany Long Draw Reservoir, Four Points Reservoir, and Snively Hot Spring. The topography is dominated by named heights like Deer Butte and Blackjack Butte, while human access is preserved through a system of rugged service roads such as Owyhee Lake Rd and Upper Tunnel Rd. This map provides a clear picture of the modern-day intersection between the high-desert environment and the irrigation engineering that supports life in the region.
