2020 Map of Brownlee Dam

About this map

Brownlee Dam anchors this stretch of the Snake River canyon, where the border between Baker County, Oregon, and Washington and Adams Counties, Idaho, is defined by the deep waters of Brownlee Reservoir. The settlement of Brownlee sits on the western shore, positioned near a landscape marked by steep drainage patterns and notable elevations such as Officer Butte and Road Mtn. Historical crossing points and river navigation are suggested by features like Ferry Canyon and the Wildhorse Rapids located near the confluence of the Wildhorse River. The terrain is deeply dissected by numerous watercourses, including Brownlee Cr and Flat Cr, which cut through the high ridges of Black Canyon and Board Gulch. This contemporary survey reflects the modern infrastructure of the Snake River, illustrating the massive scale of water management and its effect on the local topography.
