About this map

The northern reaches of Harney Lake and the Malheur National Wildlife Refuge define this arid Oregon landscape, where water management is critical to the local ecology and ranching. The presence of the St Clair Canal and scattered infrastructure like the Stock Pond Well indicate the ongoing human effort to direct seasonal flows from Silver Creek and Warm Springs Creek.

Topographical features such as Freeman Butte and the deep incisions of Brown Canyon break the flat expanse of the Harney Valley. This provisional 1990 data captures a specific era of land use in Harney County, including the isolated Reed Landing Strip, illustrating the vast distances and specialized transport required to navigate the Warm Springs Valley region. The map provides a detailed view of the drainage patterns through Sand Hollow as they converge toward the alkaline basin of the lake.
