How to Fish Union Lake
Synthesized from 1 angler reports
Union Lake produces Largemouth Bass, Walleye, Panfish / Bluegill, Northern Pike, and more. Below are season-by-season fishing patterns by species.
Spring
Spring (Pre-Spawn) Largemouth Bass on Union Lake
For spring (pre-spawn) largemouth bass on Union Lake, work lipless crankbaits worked slowly through emerging vegetation around deep reed edges adjacent to potential spawning flats (8-12 feet) with natural craw colors baits. Water temps run 48-58°F. Bass are transitioning from winter depths to shallower pre-spawn staging areas, becoming more active with warming trends Fish are beginning to feed more aggressively to prepare for spawning, focusing on larger meals near structure transitions

Spring (Spawn) Largemouth Bass on Union Lake
For spring (spawn) largemouth bass on Union Lake, work texas rigs (pitch/flip) targeting visible bed areas and reed edges around protected reed bed areas in 2-4 feet of water, especially where they meet depth changes with natural craw colors baits. Water temps run 58-65°F. Bass transitioning to spawning areas in shallow protected zones, especially near reed edges Males actively guarding nests while females move between spawning flats and slightly deeper staging areas Feeding activity increases during pre-spawn, becomes territorial during spawn

Spring (Post-Spawn) Largemouth Bass on Union Lake

Water temps run 58-68°F. Post-spawn largemouth bass are actively feeding while recovering, holding tight to reed edges with access to deeper water for quick transitions Fish are establishing typical early summer patterns, using reeds as primary cover while ambushing prey from defined edges

Summer
Summer Largemouth Bass on Union Lake
For summer largemouth bass on Union Lake, work texas rigs (pitch/flip) for precise presentations to reed edges around deeper reed edges where vegetation meets depth changes, creating prime ambush points with natural craw colors baits. Water temps run 68-82°F. Due to summer stratification in this moderate-depth lake, bass will establish distinct morning and evening shallow feeding patterns while holding deeper during midday hours Fish are actively using reed edges as primary ambush points, especially during lower light periods Bass will position tightly to structure, requiring precise casting to reed edges and depth transitions

Fall
Fall Largemouth Bass on Union Lake
For fall largemouth bass on Union Lake, work spinnerbaits worked parallel to reed edges and through transitions around deep reed edges adjacent to depth changes, especially where they meet 8-12 foot contours with natural shad colors baits. Water temps run 52-65°F. Bass are actively feeding to build energy reserves for winter, following baitfish schools and targeting high-calorie forage near reed edges and depth transitions Fish are transitioning from shallow to deeper water as temperatures cool, staging at key structural elements along the way
