2021 Map of Delamar Lake

About this map

The Delamar Flat basin dominates this portion of Lincoln County, defining a landscape shaped by intermittent water and high desert topography. This area is characterized by a series of vital water management features, including the Delamar Flat Reservoir, Southside Reservoirs, and Southeast Reservoirs, which suggest a history of managing runoff for rangeland use. The terrain is framed by the Pahroc Range to the northwest and the Delamar Mountains to the southeast, creating a broad corridor known as the Delamar Valley. This 2021 survey also details the course of Jumbo Wash as it descends from the northeast toward the flat. Notable geological landmarks such as Black Point and the nearby Black Point Reservoir provide distinct navigational points in an otherwise expansive and open desert environment.
