Delbrook Golf Course officially opened on July 21, 1928 as an 18-hole private club. In 1945 the City of Delavan purchased the course and has operated it since. As one of the oldest courses in Wisconsin, Delbrook has undergone a number of changes, including a renovation to 27 holes in 2001. By combining the new holes with the old, Delbrook offers a unique combination of traditional and modern design throughout our 27 holes. With four sets of tees, the golf course offers a challenge to the skilled golfer but will not overwhelm the less experienced.
