Portage Country Club occupies rolling terrain just north of the city of Portage. The course was built on glacial till and features naturally undulating greens that slope primarily from south to north, following the lay of the land. Sand bunkers guard most putting surfaces, with several set into the front slopes to penalize approach shots that fall short. Fairways are lined by stands of mature oak and hickory, narrowing the visual target on several holes. Water comes into play on four holes, most notably on the inward nine where a creek crosses diagonally in front of the green on the par-three thirteenth. The rough is maintained at two distinct heights: the first cut at two inches and the second at three-and-a-half inches, creating graduated penalties for shots that miss the fairway. Irrigation heads are spaced on twenty-five-foot centers, ensuring consistent turf moisture throughout the season. The course drains toward the Fox River watershed, and drainage swales are sodded rather than piped, allowing surface water to move visibly after heavy rain.
