About Lake Decatur
Set in Illinois, United States, Lake Decatur is a reservoir that holds the typical mix of warm-water and cool-water species you'd expect for the area. Anglers fishing Lake Decatur usually focus their effort on transitions: the edges of weed beds, points that stick out into deeper water, and the shaded sides of any inflow. Early morning and the last hour of light tend to be the most productive windows on a body of water this size.

Fishing Techniques
- For Largemouth bass
Vary your retrieve speed and lure presentation until you find what the bass are keying on, as their preferences can change daily based on weather and water conditions.
- For Channel catfish
Fish near structure like submerged trees or rocks, as channel catfish often use these areas for ambush points and shelter.
- For Black crappie
Vary your retrieve speed until you find what the crappie are responding to; sometimes slow and steady is best, other times a twitching action triggers strikes.
