2015 Map of Merino

About this map

Merino and the surrounding high plains of Natrona County are defined by an intricate network of drainage draws and small water catchments essential for ranching in this arid environment. The landscape is carved by Castle Cr and its tributary, S Fork Castle Cr, while numerous named depressions like Austin Draw and Hemingway Draw navigate the undulating terrain. A significant number of localized water features, including Thirtythree Mile Reservoir and N Thirtythree Mile Reservoir, underscore the importance of water management in this portion of Wyoming. Remote access is provided by unpaved routes such as Divide Rd and CR-114, which traverse the high ground between watersheds. This 2015 survey illustrates how contemporary land use remains tied to these vital water sources, providing a clear record of the physical geography used by local livestock operations.
