2011 Map of Isham Creek

About this map

John Day River flows through this rugged portion of eastern Oregon, where the landscape is defined by its network of steep gulches and isolated ranchsteads. Family names like Ricco Ranch, Kimberly Ranch, and Drinkwater Ranch mark the limited arable land along the river and its tributaries. The drainage patterns of Isham Creek and Reynolds Creek reveal a terrain dominated by elevation changes and seasonal water sources like Eureka Spring and Bumblebee Spring. Road access is primarily limited to forest routes and county highways, including County Hwy 62 and N River Rd, which follow the natural contours of the river valley. This 2011 survey captures the enduring character of Grant County's rural ranching heritage and the geographic isolation of its high-desert water systems.
