About this map

Grays Lake dominates the central portion of this 2013 topographic study, illustrating the unique wetland and aquatic environment along the border of Bonneville and Caribou counties. The settlement of Gray sits on the eastern edge of this expansive basin, which is punctuated by prominent landforms rising from the water, most notably Bear Island and the smaller Bishop Island. These interior heights provide a distinct contrast to the surrounding marshy lowlands and the seasonal drainages that feed them, such as Willow Cr and Bridge Cr.

To the west, the landscape transitions into Outlet Valley, bordered by the high ground of Little Gray Ridge. The road network, including Grays Lake Rd and W Side Rd, follows the natural contours of the basin, marking the interface between private land and the Caribou Nat For. This map captures a specific moment in the preservation and survey of this vital Idaho waterway system, where irrigation and natural flow are closely managed.
