2011 Map of Yellow Water Reservoir

About this map

Yellow Water Reservoir and its associated water management infrastructure define the character of this Petroleum County landscape. Located in a region of Montana where water security is vital for ranching and agriculture, the reservoir is held by the Yellow Water Main Dam. The drainage network is shaped by the winding paths of McDonald Creek in the north and Elk Creek across the central portion, while Yellow Water Creek flows out from the reservoir's eastern edge. The map also records smaller-scale engineering improvements like the J King Number 1 Dam and J King Number 2 Dam, reflecting the importance of private or localized water control in the early 21st century. The sparse road network and lack of dense settlements emphasize the open, rural nature of this high plains territory.
