Spring Fishing Patterns on Union Lake

Season	Species	Water Temp	Behavioral Patterns	Key Locations	Best Techniques	Forage Types	Bait Colors
Spring (Pre-Spawn)	Largemouth Bass	48-58	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	Deep reed edges adjacent to potential spawning flats (8-12 feet) Transition areas where depth changes meet emerging vegetation Secondary points with access to both shallow and deep water	Lipless Crankbaits worked slowly through emerging vegetation Bladed Jigs around reed edges and depth transitions Soft Jerkbaits worked with long pauses in deeper staging areas	Emerging Crawfish becoming active in warming shallows Resident Baitfish schools in deeper edges	Natural Craw Colors Natural Baitfish Colors Green Colors
Spring (Spawn)	Largemouth Bass	58-65	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	Protected reed bed areas in 2-4 feet of water, especially where they meet depth changes Secondary points near spawning flats Shallow protected bays with firm bottom composition	Texas Rigs (Pitch/Flip) targeting visible bed areas and reed edges Wacky Rigs worked slowly around spawning areas Soft Jerkbaits for cruising pre-spawners	Crawfish emerging in warming shallows Small bluegill relating to reed edges Young of year baitfish beginning to appear	Natural Craw Colors Green Colors Light Neutral Colors
Spring (Post-Spawn)	Largemouth Bass	58-68	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	Deeper reed edges with distinct depth changes Secondary points with emerging vegetation Inside turns of reed beds adjacent to slightly deeper water	Wacky Rigs worked precisely along reed edges Texas Rigs (Pitch/Flip) targeting pockets in reeds Soft Jerkbaits worked parallel to reed lines	Crawfish emerging in reed beds Young of year baitfish beginning to school near vegetation	Natural Craw Colors Green Colors Natural Baitfish Colors

Summer Fishing Patterns

Season	Species	Water Temp	Behavioral Patterns	Key Locations	Best Techniques	Forage Types	Bait Colors
Summer	Largemouth Bass	68-82	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	Deeper reed edges where vegetation meets depth changes, creating prime ambush points Secondary deep structure in 12-15 foot range for midday holding areas Shaded areas near reed beds during sunny periods	Texas Rigs (Pitch/Flip) for precise presentations to reed edges Frogs/Toads for early morning and evening activity over reed beds Drop Shot for targeting suspended fish in deeper water during midday	Crawfish relating to reed edges and transitions Small baitfish schools utilizing reed bed cover Bluegill and juvenile panfish in vegetation	Natural Craw Colors Green Colors Natural Baitfish Colors

Fall Fishing Guide for Union Lake

Season	Species	Water Temp	Behavioral Patterns	Key Locations	Best Techniques	Forage Types	Bait Colors
Fall	Largemouth Bass	52-65	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	Deep reed edges adjacent to depth changes, especially where they meet 8-12 foot contours Secondary points with access to both shallow and deep water Deep weed edges where vegetation meets clean bottom	Spinnerbaits worked parallel to reed edges and through transitions Soft Body Swimbaits (Small/Medium) retrieved steadily along depth changes Lipless Crankbaits burned through scattered vegetation	Young-of-year baitfish schools congregating near vegetation edges Crawfish moving along bottom in transition areas Remaining panfish schools near deeper reed edges	Natural Shad Colors Natural Craw Colors Metallic Colors

Spring (Pre-Spawn)	Largemouth Bass	Deep reed edges adjacent to potential spawning flats (8-12 feet)	Transition areas where depth changes meet emerging vegetation
Spring (Spawn)	Largemouth Bass	Protected reed bed areas in 2-4 feet of water, especially where they meet depth changes	Secondary points near spawning flats
Spring (Post-Spawn)	Largemouth Bass	Deeper reed edges with distinct depth changes	Secondary points with emerging vegetation
Summer	Largemouth Bass	Deeper reed edges where vegetation meets depth changes, creating prime ambush points	Secondary deep structure in 12-15 foot range for midday holding areas
Fall	Largemouth Bass	Deep reed edges adjacent to depth changes, especially where they meet 8-12 foot contours	Secondary points with access to both shallow and deep water
