1928–1955 {{OSM Location map The Bi-County League was formed in 1928 by eight small high schools near the
Mississippi River in west central Wisconsin:
Alma,
Arkansaw,
Cochrane,
Durand,
Fountain City,
Gilmanton,
Mondovi and
Nelson. All original members were located in two counties (
Buffalo and
Pepin), which is where the name originated from. Five years after it was founded, the conference lost three members to the new
Mississippi Valley Conference (Alma, Durand and Mondovi), along with a fourth becoming an independent in Fountain City. Pepin replaced the four departing schools, bringing the membership tally to five. Alma and Fountain City rejoined the Bi-County League in 1934 to bring membership back up to seven schools.
Plum City joined the Bi-County League in 1935, replacing Cochrane after their exit. They would rejoin the next year, bringing the conference back up to eight members. It would stay at this number for most of the next two decades, save for a season when
Maiden Rock was the Bi-County League's ninth school.
1955–1959 The Bi-County League’s membership was whittled away by rural school district consolidation in the 1950s, starting with Nelson’s closing and redistricting to Durand in 1955. Two years later, Plum City left for membership in the
Dunn-St. Croix Conference, and after the
merger of Cochrane and Fountain City in 1958, the conference was left with only five members. The Bi-County League was dissolved in 1959, with four schools (Alma, Arkansaw, Gilmanton and Pepin) forming half of the new
West Central Conference and Cochrane-Fountain City becoming members of the Mississippi Valley Conference. == Conference membership history ==
