Forsman Reservoir sits at the heart of this Valley County landscape, surrounded by an intricate network of drainages that define the high plains of northern Montana. Published as a provisional map by the U.S. Geological Survey based on data from the mid-1970s, the sheet illustrates the critical role of water management in this arid region. The terrain is deeply incised by multiple watercourses, including Buggy Creek and Wolf Creek, which wind through the breaks and coulees.
