🎣 Types of Wisconsin Bass Species
Wisconsin is home to a wide variety of freshwater bass species that attract anglers from across the Midwest. Whether you're fishing in a serene northern lake or drifting along a winding southern river, understanding the types of bass available in Wisconsin can significantly improve your success. From the aggressive strikes of largemouth bass to the deep runs of smallmouths, the state offers a bass fishing experience for every style and skill level. Here’s a complete list of all types of bass species that can be found in Wisconsin waters, including native and occasionally caught species:
🟢 1. Largemouth Bass (Micropterus salmoides)
The largemouth bass is one of the most popular game fish in Wisconsin and can be found in nearly every warm water lake, bay, slough, and slow-moving river across the state. Recognizable by its wide jaw that extends past the eye and its dark green body with a horizontal stripe, the largemouth prefers shallow, weedy environments where it can ambush prey. During the late spring and summer months, these fish become especially active and can be targeted with topwater lures, spinnerbaits, and soft plastics. Trophy specimens over 20 inches are not uncommon, and they provide an exciting challenge for bass anglers.
-
Habitat: Warm, weedy lakes, bays, sloughs, and slow rivers
-
Key Traits: Broad body, large mouth extends past the eye
-
Size Range: 12–22 inches (can reach 10+ lbs)
-
Best Season: Late spring through early fall
🔵 2. Smallmouth Bass (Micropterus dolomieu)
Known for their fierce fights and acrobatic leaps, smallmouth bass are prized among anglers who frequent Wisconsin’s clear, rocky lakes and flowing river systems such as the St. Croix and the Flambeau. These bronze-colored bass are typically found near submerged rock piles, current breaks, and ledges. Unlike their largemouth relatives, smallmouth bass prefer cooler, more oxygen-rich waters. They thrive in northern lakes and river systems and are particularly aggressive during the spring spawning season. Ranging from 10 to 20 inches, with some trophies reaching over 5 pounds, smallmouth bass are a top target for experienced anglers.
-
Habitat: Clear, rocky lakes and flowing rivers (e.g., St. Croix River, Lake Superior)
-
Key Traits: Bronze coloration, vertical bars, smaller mouth
-
Size Range: 10–20 inches (trophy fish can exceed 5 lbs)
-
Best Season: Spring and early summer, especially during spawning
🟣 3. Rock Bass (Ambloplites rupestris)
Often mistaken for young smallmouth bass, rock bass are a common panfish species found in Wisconsin's rocky-bottomed lakes and streams. They are easily identified by their red eyes, stout body, and spiny dorsal fins. While not typically targeted for sport, rock bass are frequently caught by accident when fishing for other species. They are aggressive feeders and will readily take small jigs, worms, or spinners. Though their average size ranges between 6 and 10 inches, they are considered a fun catch, especially for beginner anglers and kids.
-
Habitat: Lakes and rivers with rocky bottoms
-
Key Traits: Red eyes, compact body, often mistaken for smallmouth bass
-
Size Range: 6–10 inches
-
Fun Fact: Often called “redeye” by local anglers
🟡 4. White Bass (Morone chrysops)
White bass are a schooling fish most commonly found in larger bodies of water, such as the Lake Winnebago system and the Mississippi River. These silver-sided bass are characterized by their horizontal stripes and deep, laterally compressed bodies. During the spring spawning season, white bass migrate into rivers and streams, creating fast-paced fishing opportunities for shoreline and boat anglers alike. Averaging between 10 and 15 inches, they are known for their aggressive feeding habits and strong, sustained fights. White bass respond well to small crankbaits, blade baits, and live minnows.
-
Habitat: Large lakes and reservoirs (like Lake Winnebago system)
-
Key Traits: Silver body with horizontal stripes
-
Size Range: 10–15 inches
-
Best Time: Spring runs into tributaries for spawning
🧡 5. Hybrid Striped Bass (Wiper)
Hybrid striped bass, commonly known as “wipers,” are a cross between striped bass and white bass. Although not native to Wisconsin, they are occasionally stocked in select reservoirs and large river systems. These hybrids combine the hard-fighting traits of their striped parent with the aggressive feeding behavior of white bass, making them a thrilling catch. They have broken, irregular stripes along their silvery bodies and can grow quite large, often surpassing 10 pounds. Wipers are most commonly caught using large jigs, crankbaits, and live bait during early morning and evening feeding times.
-
Habitat: Occasionally stocked in large reservoirs or rivers
-
Key Traits: Cross between striped bass and white bass; broken stripes
-
Size Range: Can exceed 10 lbs
-
Note: Rare in Wisconsin, but caught in select stocked waters
🔴 6. Temperate Bass Group (Bonus Mention)
While largemouth and smallmouth bass belong to the "black bass" family, the temperate bass group—comprising white bass, striped bass, and their hybrids—offers a different experience for anglers in Wisconsin. These fish are not true black bass, but they are commonly grouped under the general term “bass” due to their popularity and similar appearance. Their schooling behavior and powerful runs make them an exciting target, particularly during their seasonal migrations and feeding frenzies.

Includes White Bass, Striped Bass, and Hybrid Striped Bass—these are not true "black bass" like largemouth or smallmouth, but still often grouped under the term "bass" in angling.
