Catfish Fishing Regulations in Michigan: What Every Angler Needs to Know
June 19, 2026
Michigan may be famous for its walleye and salmon, but the state’s catfish fishery is one of the most underrated angling opportunities in the Great Lakes region. From hard-fighting channel cats in southern rivers to massive flatheads lurking in deep pools, the Wolverine State offers serious catfishing for anglers willing to put in the time.
Before you rig up a rod and head to the water, you need to understand the rules that govern catfish fishing in Michigan. Michigan’s fishing regulations are updated each year, and knowing the current season dates, bag limits, size requirements, and license rules keeps you on the right side of the law — and helps protect the fishery for future generations.
Key Insight: The 2026 Michigan Fishing Regulations are in effect from April 1, 2026, through March 31, 2027. Always verify the current rules directly with the Michigan DNR before your trip.
Catfish Species Found in Michigan
Michigan is home to several members of the catfish family (Ictaluridae), though two species dominate the sport fishing scene. Understanding which species you are targeting helps you choose the right tactics, locations, and gear.
Channel Catfish — Channel cats, with their deeply forked tail, are the most popular of the catfish. They have two dorsal fins including one adipose fin, barbels around the mouth, and a slender body with speckled sides. Channel catfish live in all Great Lakes but Superior, as well as inland lakes and medium to large rivers. They are most common in the southern half of the Lower Peninsula. In productive waters, channel catfish often grow to over 30 inches and weigh more than 10 pounds. The current state record channel catfish weighed 40 pounds.
Flathead Catfish — Flathead catfish can vary in color from dark brown to yellowish. Unlike channel catfish and others, the flathead does not have a forked tail. It also has a protruding lower jaw. Flatheads can reach Michigan record weights of 50+ pounds. They are found in large rivers, streams, inland lakes, and the Great Lakes, usually over hard bottoms. They prefer deep, sluggish pools with logs and other submerged debris that can be used as cover.
Bullheads — Michigan also has several species of the bullhead family, including black, brown, and yellow bullheads. Bullheads are smaller fish, averaging 1–2 pounds and rarely exceeding 8 pounds. All three species have sharp dorsal and pectoral spines, so handle them with care. Bullheads are widely distributed across the state and are especially popular with younger or beginner anglers due to their willingness to bite.
You can learn more about the full range of catfish varieties in our guide to different types of catfish.
Pro Tip: To tell a channel catfish from a flathead, check the tail and the jaw. The channel cat has a deeply forked tail, while the flathead has a rounded tail and a protruding lower jaw that resembles an underbite.
Catfish Season Dates in Michigan
One of the most angler-friendly aspects of Michigan catfishing is the open season. Channel catfish and flathead catfish are listed among the species open for the entire year across the Great Lakes, Lake St. Clair, and the St. Clair and Detroit rivers. This year-round access applies to most major waters in the state.
For inland waters across the Lower and Upper peninsulas, catfish are similarly not subject to a closed season under Michigan’s general statewide regulations. The 2026 Michigan Fishing Regulations are in effect until March 31, 2027. This means you can pursue catfish in most Michigan waters throughout the calendar year under the current regulatory period.
| Water Type | Channel Catfish Season | Flathead Catfish Season |
|---|---|---|
| Great Lakes (except Lake Superior) | Open all year | Open all year |
| Lake St. Clair / St. Clair River / Detroit River | Open all year | Open all year |
| Inland lakes and rivers (Lower Peninsula) | Open all year | Open all year |
| Upper Peninsula inland waters | Open all year | Open all year |
Important Note: Some gear-restricted streams have special seasonal rules that may affect fishing methods even when catfish are technically in season. Always check pages 44–46 of the 2026 Michigan Fishing Regulations for gear-restricted stream details before fishing.

Daily Bag Limits for Catfish in Michigan
Michigan’s bag limits for catfish are relatively generous compared to many other game fish in the state, which reflects the species’ resilience and productivity in Michigan waters.
Under the statewide general regulations, channel catfish must be larger than 12 inches in Michigan, and there is a daily limit of 10 fish. This 10-fish daily possession limit applies to channel catfish across most inland waters.
For flathead catfish, the Michigan DNR regulates them alongside channel catfish in the general species table. The statewide daily possession limit for flathead catfish also falls within the general “other species” framework, and anglers should confirm current limits in the official 2026 Michigan Fishing Regulations digest, as specific waters can carry different rules.
| Species | Daily Bag Limit (General Statewide) | Notes |
|---|---|---|
| Channel Catfish | 10 fish | 12-inch minimum size applies |
| Flathead Catfish | Consult 2026 DNR digest | Special water rules may apply |
| Bullheads (black, brown, yellow) | No statewide limit | Check local water restrictions |
Important Note: The general regulations table provides statewide regulations for the listed species. However, there are many waters in the state that have fishing regulations which differ from those in this table. Always cross-reference the specific water body you plan to fish.
Possession limits in Michigan are directly tied to the daily bag limit. The daily possession limit — also known as the bag limit — is the total number of fish that may be caught and retained in one calendar day. If you are fishing over multiple days, the possession limit may differ, so review the definitions section of the regulations handbook carefully.
Size and Length Limits for Catfish in Michigan
Michigan enforces a minimum size limit for channel catfish to protect younger fish and ensure the population stays healthy. Channel catfish must be larger than 12 inches in Michigan. Any channel cat you catch that does not meet this threshold must be returned to the water immediately.
For flathead catfish, there is no separate statewide minimum size limit listed under the general regulations, but individual water bodies can carry special rules. Given that flatheads on average are substantially larger than channels, and a large flathead in Michigan can exceed 50+ pounds, most anglers targeting trophy flatheads are naturally catching fish well above any minimum threshold.
Bullheads do not carry a statewide minimum size requirement under Michigan’s general regulations, which makes them a popular target for casual anglers and families looking for easy action.
| Species | Minimum Size Limit | Where It Applies |
|---|---|---|
| Channel Catfish | 12 inches | Statewide general rule |
| Flathead Catfish | No general statewide minimum | Check individual water body rules |
| Bullheads | No statewide minimum | Statewide |
Pro Tip: Always carry a measuring device when catfishing. Channel cats close to the 12-inch minimum are common in many Michigan rivers, and releasing undersized fish quickly improves their survival rate.

Legal Methods for Catching Catfish in Michigan
Michigan allows a range of legal fishing methods for catfish, giving you plenty of flexibility in how you approach the water. The most common and productive approach is standard rod-and-reel fishing, but the state also permits several other techniques.
Rod and Reel / Pole Fishing — This is the go-to method for most Michigan catfish anglers. Channel cats are typically pursued by anglers using live, dead, or cut bait, though anglers have long used all manner of bait presented on the bottom — cheese, shrimp, liver, spawn — or commercially prepared blood or scent baits. One of the best ways to fish for catfish is by using nightcrawlers, small fish, chicken livers, or stink baits that attract catfish from afar. Bottom fishing with a slip sinker rig or a Carolina rig is a preferred method.
Gear Considerations — Whether you prefer spinning reels or baitcasting reels, be sure to use a stout, quality fishing rod. Medium-heavy or heavy action rods in the seven-foot range tend to be ideal. Spool your reel with 15-to-50-pound monofilament, fluorocarbon, or braided line, depending on the size and types of catfish you expect to encounter. Browse our guides on different types of fishing rods and types of fishing reels to find the right setup for catfish.
Bow and Spearfishing — Michigan does permit bowfishing and spearfishing for certain species. Underwater spearfishing opportunities have expanded to additional Great Lakes waters, though some areas remain excluded. While anglers no longer need to submit monthly reports for this activity, they are still required to obtain a free spearfishing license. Check the bow- and spearfishing regulations table in the 2026 Michigan Fishing Regulations for species-specific rules.
Flathead-Specific Tactics — Flatheads are caught mostly on live bait fish and only occasionally on cut or prepared baits. They shelter in cover of submerged logs or other large structures. After dark is prime fishing time for catching flathead catfish.
- Bottom rigs with live bluegill or other baitfish are highly effective for flatheads
- Cut bait, stink bait, and prepared scent baits work well for channel cats
- Limb lines and trotlines may be used in some Michigan waters — check the netting regulations section of the DNR digest for current rules on passive gear
- Jug fishing is practiced by some anglers; verify legality on specific water bodies with the Michigan DNR before use
Common Mistake: Using gear that is legal on one water body but restricted on another. Gear-restricted streams in Michigan have specific rules that limit the types of tackle and methods allowed. Always check pages 44–46 of the 2026 regulations digest before fishing a river or stream you haven’t fished before.

Fishing License Requirements for Catfish in Michigan
You need a valid Michigan fishing license to target catfish on public waters. There are no species-specific stamps or endorsements required for catfish — your standard all-species license covers it.
All anglers ages 17 and older are required to purchase a fishing license to fish public waters in Michigan; these licenses are good for all species, though additional reporting requirements apply to some species and fishing methods.
As of the 2026 license year, the Michigan DNR has set the following fees:
| License Type | Cost (2026) | Valid Through |
|---|---|---|
| Resident Annual | $26 (+ $1 surcharge) | March 31, 2027 |
| Nonresident Annual | $76 (+ $1 surcharge) | March 31, 2027 |
| Senior Annual (residents 65+) | $11 (+ $1 surcharge) | March 31, 2027 |
| Daily (24-hour) | $10 | 24 hours from purchase |
You can purchase an annual fishing license at $26 for Michigan residents or $76 for nonresidents. A senior annual fishing license is available at $11 for Michigan residents 65 and older or residents who are legally blind. A daily fishing license costs $10 per day for Michigan residents and nonresidents 17 and older and is valid for 24 hours.
Michigan offers an optional youth license for anglers 16 and under, but it is not required for kids to fish — they still must follow all rules.
Anglers can purchase 2026 fishing licenses through the Michigan DNR Hunt Fish app or the department’s website. The app also provides tools for reporting harvests and accessing the full text of current regulations.
Pro Tip: Michigan offers two free fishing weekends: a Winter Free Fishing Weekend (February 14–15, 2026) and a Summer Free Fishing Weekend (June 13–14, 2026). These are great opportunities to introduce a new angler to catfishing without the upfront license cost.
Fishing license fees are waived for full-time, federal, active-duty U.S. military personnel. Additional exemptions apply to certain residents — consult the official 2026 Michigan Fishing Regulations digest for a complete list.

Best Catfish Fishing Spots in Michigan
Michigan’s river systems and large inland lakes deliver some of the best catfishing in the Midwest. The most productive waters are concentrated in the southern Lower Peninsula, where warmer temperatures support larger catfish populations.
Saginaw River — The Saginaw River is one of Michigan’s premier catfish destinations. Saginaw Bay and the lower Saginaw River deliver excellent fishing throughout the warmer months, with catfish listed among the target species alongside walleye, yellow perch, and smallmouth bass. There are numerous public launches and select shore and pier areas for access. The deeper pools and bends of the lower Saginaw hold both channel cats and flatheads, with the best action typically after dark during summer.
Grand River — The Grand River, Michigan’s longest river, winds through the heart of the Lower Peninsula and offers consistent channel catfish fishing from spring through fall. Deep holes near bridges, log jams, and undercut banks are prime holding areas. The stretch near Grand Rapids and downstream toward Lake Michigan sees regular catfish activity.
Kalamazoo River — The Kalamazoo River in southwest Michigan produces solid channel catfish numbers, particularly in the slower, deeper sections of the lower river. Adult catfish typically inhabit deep pools with log jams or rocks for cover during the day and move into shallow water at night, making the Kalamazoo’s varied structure ideal habitat.
St. Clair River and Lake St. Clair — Channel catfish and flathead catfish are among the species regulated on Lake St. Clair and the St. Clair and Detroit rivers. These connecting waters between Lake Huron and Lake Erie see significant catfish activity, particularly for larger channel cats drawn to the strong current and abundant forage.
Flint River — The introduced population of flathead catfish in the Flint River system was found to prey largely on crayfish, making it a productive flathead fishery. The Flint River’s deep runs and woody structure provide classic flathead habitat.
Houghton Lake — The state record channel catfish was caught from Houghton Lake, making it a legendary destination for anglers chasing trophy-sized fish. This large inland lake in Roscommon County supports a healthy channel cat population and is accessible from multiple public launch sites.
Detroit River — The Detroit River provides year-round catfish access and is known for its diverse warmwater fishery. The Detroit River area offers catfish alongside walleye, with shore access available at Sterling State Park and nearby boat launches in Monroe.
- Target deep pools, river bends, and areas with submerged logs or rock structure
- The best fishing periods for channel catfish are from dusk until midnight or when water levels are rising after rains have washed food into the lake or stream
- Live bait such as bluegill or suckers is the top choice for large flatheads
- Cut shad, chicken liver, and prepared stink baits consistently produce channel cats
- Fish the warmest months — June through September — for peak catfish activity in Michigan rivers
Key Insight: Michigan is an often overlooked fishery when it comes to targeting catfish. The state has two major species — channel catfish and flathead catfish — that are some of the most underrated fish in the state. Southern Michigan rivers offer serious trophy potential for anglers willing to fish after dark.
