About this map

The Cheyenne River Indian Reservation landscape is defined here by the winding course of the Moreau River as it enters Lake Oahe. This 1952 topographic study, later updated with 1980s aerial revisions, documents the hydraulic transition where riverine currents meet the expanded waters of the reservoir. The topography is etched by numerous drainage systems, including Marshall Creek and Hardboy Creek in the north, and Blue Beaver Creek to the south.

Evidence of local community life is centered on St Marys Ch, a solitary landmark near the river's bend. The map illustrates a complex network of seasonal watercourses like Jolley Creek and Veo Creek that carve through the high ground, reflecting the erosion patterns of the Missouri River Basin. This document serves as a detailed record of land use and hydrology within the reservation before further modern development altered these traditional drainage patterns.
