A decision by the North Dakota supreme court on May 24, 1901, resurrected Bowman County.

That decision also caused the county's area to slightly increase; its former boundary descriptions were replaced by descriptions based on the boundary lines of adjacent jurisdictions, which added a strip along its south border and another strip along its east border.

However, on June 10, 1907, ND Governor John Burke issued a proclamation which re-created Bowman County.

The Little Missouri River flows northward through the west part of the county; the North Fork of the Grand River flows easterly through the lower part of the county, filling Bowman-Haley Lake in the process.

Spring Creek flows south-southeasterly through the central part of the county, discharging into Bowman-Haley Lake.

Its highest point is on the south boundary line, toward its southwestern corner, at 3,228 ft (984 m) ASL.

In terms of ancestry, 47.4% were German, 28.1% were Norwegian, 9.9% were Irish, 6.4% were Swedish, 6.4% were English, 5.4% were American, and 5.2% were Polish.
