About this map

Lyman Lake State Park dominates the northwest corner of this high-desert landscape in Apache County, where the reservoir is fed by the Little Colorado River as it flows north through the Richville Valley. The geography reflects a mix of public recreation and private ranching, with a campground and boat ramp serving visitors on the western shore while the Voigt Ranch and various corrals mark the agricultural use of the surrounding mesas.

Hydrology is the primary driver of life here, evidenced by several named water sources like Neilson Spring and Coyote Creek cutting through the arid terrain. The map's contour lines illustrate the significant elevation changes near Scraper Knoll and along the river's path, including technical details such as a gaging station used to monitor water levels in this critical watershed. This edition includes 1984 revisions to woodland and purple-tinted updates to physical features, showing the state of the area's development in the late 20th century.
