2024 Map of Drews Reservoir

About this map

Drews Reservoir dominates the drainage of this portion of south-central Oregon, where the high desert terrain meets the eastern edge of the Fremont National Forest. The reservoir is fed by a complex network of seasonal and perennial streams, including Stevenson Creek, Drews Creek, and Chandler Creek, which flow through Drews Valley before reaching the impoundment. The landscape is defined by significant elevation changes, rising from the valley floor toward the Willow Creek Hills and the prominent La Sere Point. Named water sources like Kerman Spring, Salt Spring, and Dip Spring suggest the importance of reliable water in this arid environment. The map details the transition from the forested mountain slopes in the west to the more open, creek-carved flats of the eastern range.
