1983 Map of Haynie Reservoir

About this map

Haynie Reservoir centers this landscape in McCone County, illustrating a typical mid-century water management pattern in the Missouri River basin. This 1983 provisional survey highlights a terrain defined by complex drainage systems and intermittent waterways rather than permanent settlements. To the north and south, the sheet documents the intricate headwaters of several major prairie drainages, including Cow Creek and the meandering path of Lost Creek. The topography around South Fork Buffalo Creek and Denwoody Creek reveals a largely unpopulated cattle-grazing or dryland farming environment during the late 1970s and early 1980s. This specific survey is particularly valuable for researchers tracing the precise course of these seasonal water bodies before modern agricultural or land-use changes altered the local hydrology.
