Free-fishing days and youth exemptions follow the statewide South Dakota rules.

Only where they conflict. South Dakota's statewide 2026 regulations apply on Angostura Reservoir by default; the overlays above replace the matching statewide rules for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.
