The Missouri River carves through the southeastern corner of this Chouteau County landscape, creating a dramatic break in the high plains terrain marked by Widow Coulee and Portage Coulee. The small settlement of Floweree serves as a local focal point in the northeast, while the community of Portage is situated along the western edge. This 2011 survey documents a highly managed water system essential for local agriculture, featuring Floweree Lake and several man-made structures including Robertson Dam and Lars Dam.
