About this map

Upper Tumalo Reservoir and the Tumalo Dam anchor this Deschutes County landscape, illustrating the complex irrigation infrastructure essential to central Oregon. The map documents an intricate network of water management features, including the Columbia Southern Canal, Tumalo Feed Canal, and several historic waterways like Maxwell Ditch and Snow Creek Ditch. These systems historically transformed the arid terrain of Bull Flat into viable ranching and agricultural land.

Residential growth is evident in the northern portion of the quadrangle near the settlement of Plainview, where modern road layouts like Cascade Estates Dr contrast with the older, more utilitarian grid of the Gist area. Aviation history is represented by the Sage Ranch Airport, while family-named routes such as Fryrear Ranch Rd and Livesay Rd indicate the area's deep-rooted agricultural heritage and private landholdings.
