1967 Map of Krumbo Reservoir

About this map

Malheur National Wildlife Refuge dominates this section of Harney County, illustrating a complex hydrological system designed for habitat management in the high desert. The Blitzen Valley floor is a network of managed water features, including the Krumbo Canal, Warm Springs, and the Blitzen River, which feed into larger bodies like Baca Lake 4154 and Knox Pond. The human footprint is defined by the Witzel Ranch and infrastructure such as the Krumbo Reservoir Spillway and a remote Landing Strip. These features reveal how the landscape was engineered for both ranching and conservation during the mid-20th century. Beyond the wetlands, the terrain rises toward volcanic landmarks like Krumbo Butte and the curiously named Dutch Oven depression, while numerous Borrow Pits and Prospects suggest local mineral exploration and material extraction for road maintenance like the Patrol Road.
