2023 Map of Poison Creek Slough

About this map

The low-lying Harney Basin landscape is defined here by a intricate network of waterways and irrigation infrastructure centered around the Poison Creek Slough. The terrain is marked by the presence of the East Fork Silvies River and numerous distributary channels including Foley Slough, Embree Slough, and Gapman Slough, which weave through the agricultural sections of Harney County. This contemporary study shows how the land is partitioned for ranching and aviation, notably featuring the Burns Municipal Airport and its runways located south of N Steens View Ln. The local road system, including Red Barn Rd and Old Experiment Rd, follows the rectangular Public Land Survey System grid, while Hwy 20 and Crane Blvd cut diagonally across the wetlands. The inclusion of the Upper Hanley Canal illustrates the ongoing importance of water management in this high-desert environment.
