The WIAA’s newly released 2026-27 Division 3 girls basketball sectional assignments carry an unusual distinction: both of last year’s second-half sectional champions — Oostburg and Kettle Moraine Lutheran — have been promoted to Division 2, while two Division 2 programs and a Division 4 dropout fill in behind them.
Two champions, gone up a level
Oostburg won last year’s Sectional 3 title 62–43, and Kettle Moraine Lutheran took Sectional 4 with a 70–43 win. Both are now Division 2 programs for 2026-27, confirmed on this year’s Division 2 assignment sheet in the same new Sectional 3.
Marinette and Green Bay East arrive from Division 2
Filling part of the gap, Marinette and Green Bay East both played Division 2 basketball in 2025-26 and drop to Division 3 for 2026-27, landing together in Sectional 2.
Barron drops to Division 4
Barron played Division 3 basketball in 2025-26 but doesn’t appear on the 2026-27 Division 3 sheet; the 2026-27 Division 4 assignments confirm the Golden Bears have moved down, landing in Division 4 Sectional 1.
The two surviving champions land together
Saint Croix Central and Wisconsin Dells, which won last year’s Sectional 1 and Sectional 2 titles respectively, both land in the same Sectional 1 for 2026-27 — a pairing similar to the boys Division 1 story where two reigning sectional champions were placed in the same bracket.
