Unit 31 Boundary
That portion of WASHINGTON COUNTY within the following boundary: beginning at Brownlee Dam on the Snake River, then southeast on State Highway 71 to U.S. 95, then southwest on U.S. 95 to the Snake River at Weiser, then down the Snake River to the point of beginning.
Brownlee Zone Context
West-Central Idaho — Snake River Reservoirs
Brownlee covers the country around Brownlee, Oxbow, and Hells Canyon reservoirs. It's lower-elevation, drier, and earlier-season than most Idaho elk zones, making it a logical choice for archery hunters.
Heat is the under-rated challenge in early seasons. Cambridge and Council are the realistic supply points.
