Cattail Crossing Golf Course in Watertown, South Dakota, opened in 2004 as a municipal facility designed by Garrett D. Gill. The course sits on the northern plains of South Dakota, where the landscape transitions between prairie and glacial lake country. Watertown itself lies near several natural lakes, and the course takes its name from the wetland vegetation common to the region. The facility features 27 holes divided into three nine-hole loops—Red, Yellow, and Blue—allowing for multiple 18-hole combinations. The Red/Yellow pairing represents one of these configurations. Gill's routing works with the relatively flat to gently rolling terrain typical of eastern South Dakota, incorporating native grasses and water features that reflect the area's wetland character. The design emphasizes playability for a range of skill levels while maintaining strategic interest through bunkering and hazard placement. As a municipal course in a community of roughly 20,000 residents, Cattail Crossing serves as the primary public golf option for Watertown and the surrounding region. The facility includes standard practice amenities and a clubhouse with food service. The course hosts local tournaments and league play throughout the South Dakota golf season, which typically runs from late April through October depending on weather conditions.
