- Main species:
- Walleye, northern pike, smallmouth bass
- Best time:
- Late spring through early fall offers changing opportunities along points and bays.

Seasonal tips
- spring

- summer
- Post-runoff rivers offer hatch and terrestrial fishing, while prairie reservoirs provide warmwater alternatives. Check heat-related restrictions before every trout outing.
- fall
- Cooler water can improve trout activity and reservoir predator fishing. Avoid walking through spawning redds in shallow gravel.
- winter
- Selected tailwaters remain open water, but weather and shelf ice limit access. Ice fishing on lakes requires current local safety information.
