Published WIAA placements. A program's placement enrollment can differ from the school's annual student count, especially for co-ops. Missing seasons are not estimated.
Compiled by Ewert Sports from WIAA team pages and WIAA placement reports. These are WIAA enrollment figures, not district-wide enrollment or a division calculation. Missing years are not estimated; co-op totals and sport-specific counts are kept separate.
District enrollment · 2005–2025
Wisconsin DPICertified total enrollment for Riverdale High, published by the Wisconsin Department of Public Instruction. This is not the WIAA placement figure above — WIAA counts on its own date and, for many sports, over a subset of grades. The two are kept separate and are not comparable year to year.
