2018 Map of Little Tanks

About this map

Diamond Butte stands as a prominent landmark in this high-desert reach of Mohave County, where the landscape is defined by an extensive system of water management features necessary for life in the arid West. The 2018 survey reveals a network of man-made catchments including Alva Shelly Reservoir, Walter Shelley Reservoir, and the dual Sevy Draw Reservoir Number One and Number Two. These features, alongside the namesake Little Tanks, suggest a history of ranching or livestock management integrated into the natural drainage of Sevy Draw and the broad Main Street Valley. The map documents the persistent human effort to capture seasonal runoff in a region where water sources like Nina Pond and Rattlesnake Reservoir are critical infrastructure. This modern topography captures the region as it remains intersected by rural routes such as Co HWY 105 and Co RD 5, providing a detailed look at contemporary land use in a sparsely populated section of the Arizona strip.
