2023 Map of Manastash Creek

About this map

Manastash Ridge and Umtanum Ridge dominate this section of the central Washington landscape, creating a series of deep canyons and high passes. The terrain is defined by the drainage systems of Manastash Creek and Umtanum Creek, which cut through the ridges toward the Yakima Valley. Local water management is visible through the KRD (Kittitas Reclamation District) infrastructure, including the South Branch Canal and its South Branch Extension, which bring irrigation to the higher elevations.
