Dunn-St. Croix Conference
The Dunn-St.Croix Conference is a high school athletic conference with its catchment in western Wisconsin. Founded in 1930, the conference and its member schools belong to the Wisconsin Interscholastic Athletic Association.
History
1930-1944
The Dunn-St. Croix Conference was formed in 1930 by eight small high schools in western Wisconsin: Baldwin, Boyceville, Downing, Elk Mound, Glenwood City, Hammond, Roberts and Woodville. The conference was named after the two counties that all eight original member schools were located in. Elk Mound left the conference in 1931 for membership in the Little Eight Conference, and the next year, Dunn County Agricultural School and Elmwood became Dunn-St. Croix Conference members. Football was added as a sponsored sport in 1934, and four members made up the initial roster. Elk Mound returned to the Dunn-St. Croix in 1937 after the Little Eight Conference was folded, and the ten member schools subdivided into eastern and western divisions:| Eastern Division | Western Division |
| Boyceville | Baldwin |
| Downing | Elmwood |
| Dunn County Aggies | Hammond |
| Elk Mound | Roberts |
| Glenwood City | Woodville |
In 1938, the Dunn-St. Croix Conference shifted from eleven-player to eight-player football league-wide, after the Dunn County Aggies made the switch the year prior. Sponsorship of interscholastic football was abandoned by the Dunn-St. Croix Conference during World War II, and would not make its return until several years later.
1944-1960
The Dunn-St. Croix Conference's two-division alignment lasted until 1944, when Downing High School was closed and redistricted to Glenwood City. In 1949, the ledger further shrunk to seven schools, as Baldwin and Glenwood City exited for membership in the Middle Border Conference. Prescott joined the Dunn-St. Croix Conference in 1951 to bring membership back up to eight schools, the same year the conference reinstated eight-player football as a sponsored sport. In 1953, the Dunn-St. Croix Conference suspended football sponsorship for a second time, and its members entered the new 856 Conference. A ninth school was added to the membership roster in 1955 when Somerset became members after being displaced from the Northwest Border Conference's closing. In 1956, Elk Mound became members of the Cloverbelt Conference, and Plum City joined from the Bi-County League in 1957 to replace Dunn County Agricultural School after its closing. The Dunn-St. Croix Conference also reinstated sponsorship of football that year after the 856 Conference ceased operations.1960-1988
In 1960, the high schools in Hammond and Roberts were combined to form the new St. Croix Central High School, inheriting their predecessors' place in the Dunn-St. Croix Conference. The next year, Woodville was merged with Baldwin, and the newly minted Baldwin-Woodville Area High School inherited Baldwin's Middle Border Conference membership. They were replaced by Arkansaw from the West Central Conference and Elk Mound from the Cloverbelt Conference, with the latter making their return to the Dunn-St. Croix after a five-year absence. Football also made the switch from eight-player to eleven-player in 1961, with several schools playing the regulation variant for the first time. Arkansaw's time in the Dunn-St. Croix Conference would be short-lived, as they returned to the West Central Conference in 1964. The conference accepted two new members in the second half of the 1960s, with Pepin joining from the West Central Conference and Colfax moving over from the Middle Border Conference. The 1970s began for the Dunn-St. Croix Conference with the exit of Prescott to the Middle Border Conference and two new schools joining in 1972: Glenwood City and Spring Valley. Both incoming schools came from the Middle Border with Glenwood City making its return to the conference after its exit in 1949. Membership remained stable for five years until 1977, when Somerset exited for membership in the Upper St. Croix Valley Conference. They were replaced by two former members returning to the Dunn-St. Croix: Arkansaw and Prescott.1988-2002
By 1988, two Dunn-St. Croix members based in Pepin County saw enrollment dwindle to levels that would make further athletic competition unsustainable. The two schools entered into a cooperative agreement under the Pepin/Arkansaw banner that year, an arrangement that would last until Arkansaw was folded into Durand's school district in 1992. Two years later, Somerset made their return from the Upper St. Croix Valley Conference and Mondovi joined from the Middle Border Conference. The Dunn-St. Croix Conference was divided by enrollment into large schools and small schools for most sports that year:| Large Dunn-St. Croix | Small Dunn-St. Croix |
| Elk Mound | Boyceville |
| Glenwood City | Colfax |
| Mondovi | Elmwood |
| Prescott | Pepin |
| Somerset | Plum City |
| St. Croix Central | Spring Valley |
2002-present
In 2002, Prescott and Somerset both ended their second stints in the Dunn-St. Croix Conference when they both joined the Middle Border Conference, and the conference realigned as a single division. The Dunn-St. Croix Conference lost Pepin as members in 2009 when they entered into a cooperative athletic partnership with Alma and joined the Dairyland Conference. Elmwood and Plum City consolidated their athletic programs in 2014, with both schools staying in the conference. In 2016, St. Croix Central traded affiliations with Durand-Arkansaw, with the latter entering from the Middle Border Conference. The membership roster remained stable until 2025, when Elk Mound returned to the Cloverbelt Conference and two schools joined as their replacement: Chetek-Weyerhaeuser moved over from the Heart O'North Conference and Clear Lake of the Lakeland Conference.Football (since 2020)
In February 2019, in conjunction with the Wisconsin Football Coaches Association, the WIAA released a sweeping football-only realignment for Wisconsin to commence with the 2020 football season and run on a two-year cycle. Four members were retained from the Dunn-St. Croix football roster, and three new associate members were added along with full members Elmwood/Plum City. This alignment was kept intact for the 2022-2023 competition cycle. For the 2024-2025 cycle, Cadott was shifted to the Lakeland Conference as football-only members, and the Dunn-St. Croix entered into a mandatory crossover scheduling partnership with the Lakeland. In 2026, McDonell Central Catholic and Osseo-Fairchild are set to replace Clear Lake and Turtle Lake, who are transitioning to eight-player football and membership in the North Central Conference.Membership timeline
