About this map

Eagar and the surrounding Round Valley landscape are defined by a sophisticated network of high-elevation water management systems within the Apache National Forest. This 2021 survey illustrates how the drainage of Nutrioso Cr and Milligan Cr is captured by numerous small-scale impoundments such as McKay Reservoir, Glen Livet Reservoir, and Trinity Reservoir. These features, along with dozens of livestock tanks like Basin Tank and Loco Knoll Tank, trace the ongoing reliance on seasonal runoff in this part of Apache County.

Local history is marked by quiet landmarks like the Butler Cem and a network of named trails, including the Homestead Trl and Murray Basin Trl, which navigate the varied terrain of Picnic Hill and Molina Basin. The map also reveals geologically distinct features such as the Mesa Sink Hole and Indian Tank Hill, providing a detailed look at the interface between the settlement at Eagar and the managed forest lands.
