About. Morone chrysops — A hard-fighting open-water schooling bass of big reservoirs and their feeder rivers across the Plains and Midwest. White bass run up tributaries by the thousands to spawn in spring — the run is a calendar event on waters like McConaughy and the Missouri reservoirs — then chase shad in surface-busting "jumps" through summer. Often hybridized with striped bass to make the "wiper." Abundant and lightly regulated, so creel limits are generous or absent.
Prefers. Water 55–80°F (ideal 68°F) · either tide · depth 4–30 ft.
- Daily creel
- no limit
Illinois: no statewide daily limit on white bass (abundant on the big rivers and reservoirs).
