About this map

Eagle Rock Reservoir sits atop the high plains of northern Weld County, serving as a primary water landmark in this arid section of the Colorado-Wyoming borderlands. The landscape is defined by dramatic erosion features, most notably the Chalk Bluffs and the deeply incised drainage of Bull Canyon. These geological formations break the steady sweep of the range, creating a complex series of draws and ridges that direct the intermittent flows of Simpson Cr and Little Crow Cr.
