2011 Map of Black Sea Reservoir

About this map

Black Sea Reservoir and the intricate drainage of West Blacktail Creek define this rural landscape in Rosebud County. The map reveals a highly engineered watershed, marked by a dense system of earthen works managed for water storage in the arid Montana plains. Numerous private or regional water control structures, such as Big Timber Number 14 Dam and Big Timber Number 10 Dam, dot the tributary lines leading toward larger basins. These dams reflect the essential role of water management for local ranching and agricultural sustainability. To the north, McGinnis Creek meanders across the quadrangle, flanked by additional numbered improvements like the L Galt Number 20 Dam and Galt Number 22 Dam. This topographic survey provides a precise record of these water-related landmarks and the unimproved roads that connect them across the basin floor.
