About this map

Water management dominates this arid New Mexico landscape, where a series of tanks and small catchments reveal the essential infrastructure of ranching in Otero County. Features such as Double Mills Reservoir and Lower Steer Pasture Tank highlight the necessity of reliable water sources for livestock across these high desert flats. The terrain is marked by subtle topographic shifts between drainage basins, serving the larger agricultural and ranching operations of the region. Local names like Road Tank, Sand Tank, and Long Tank indicate a history of land use focused on directing seasonal runoff. This survey provides a clear view of the Public Land Survey System boundaries, specifically where t11s r8e meets t12s r8e, tracing the grid that defined settlement and property lines in this part of the Southwest.
