About this map

Parker Dam anchors this desert landscape where the Colorado River defines the border between Arizona and California. The map documents a complex water management infrastructure, featuring the Gene Wash Reservoir and the Copper Basin Reservoir, which are connected by the Colorado River Aqueduct through engineering feats like the Whipple Mountain Tunnel and Copper Basin Tunnel. These facilities represent the critical mid-century development required to move water across the Mojave.

Recreational and small-scale settlements are concentrated along the water's edge, including Black Meadow Landing on Lake Havasu and the community of Parker Strip further south. The surrounding terrain is dominated by the Whipple Mountains and Aubrey Hills, with the Bill Williams River joining the main channel near the dam. Local transport is facilitated by roads like Lake Shore Blvd and Parker Dam Rd, while the Gene Wash Reservoir Airport serves the immediate utility operations.
