Bass Fishing Regulations in Michigan: Season Dates, Limits, and Rules You Need to Know
June 14, 2026
Michigan is one of the most productive bass fishing states in the country, but fishing legally here means knowing the rules before you rig up your rod. With over 11,000 inland lakes and shorelines on four of the five Great Lakes, Michigan is a freshwater fishing paradise — and that diversity comes with a regulation system that varies by water body, region, and species.
Whether you’re targeting largemouth in a weedy southern lake or chasing trophy smallmouth along the rocky shores of Lake St. Clair, the bass fishing regulations in Michigan govern everything from when you can keep fish to how many you can take home. Getting these details right keeps you on the right side of a conservation officer and helps protect the fishery for future seasons.
This guide covers every major regulation category you need to understand, based on the 2026 Michigan Fishing Regulations, which are in effect until March 31, 2027.
Bass Species Covered by Fishing Regulations in Michigan
Michigan supports two primary bass species that anglers target throughout the season: largemouth bass and smallmouth bass. Both species are widely distributed across the state, though they tend to favor different habitat types and water conditions.
Largemouth bass are the most recognizable of the two. They have two dorsal fins with a deep notch between the spinous and soft-rayed portions, a body longer than deep, and an upper jaw that extends beyond the rear of the eye, with a body usually light green with a dark green lateral streak. Largemouth bass can grow larger than 20 inches and exceed 7 pounds in Michigan waters, and they are seldom found deeper than 20 feet.
Smallmouth bass are the other primary target, and Michigan’s waters are nationally recognized for producing trophy-class fish. Michigan’s Great Lakes and connecting waters have excellent smallmouth populations, and the whole southeastern coast from Port Huron to Lake Erie is nationally known for its size and number of smallmouth bass.
In addition to largemouth and smallmouth, Michigan regulations also address rock bass and warmouth, which are regulated separately and generally have no size limit or a more generous bag limit. For the purposes of this guide, all season dates, size limits, and bag limits discussed below apply specifically to largemouth and smallmouth bass unless otherwise noted.
Key Insight: Both largemouth and smallmouth bass fall under the same statewide size and bag limit framework in Michigan, but individual water bodies may carry special rules that override the statewide defaults. Always check county-specific exceptions before fishing a new lake or river.
Bass Fishing Season Dates and Closures in Michigan
Michigan uses a two-part season structure for bass: a year-round catch-and-immediate-release season and a separate possession season when you are allowed to keep fish. Understanding the difference between these two seasons is essential before you head out.
Catch-and-Immediate-Release (CIR) fishing for bass is allowed all year on all waters, unless otherwise closed to fishing. All bass caught must be immediately returned to the water. This means you can fish for bass in January, February, or any other month — you simply cannot keep what you catch outside of the possession season.
For the 2026 regulation year, catch-and-immediate-release bass fishing is open year-round statewide. The possession season opens the third Saturday of May — May 23, 2026 — statewide, except on Lake St. Clair, the St. Clair River, and the Detroit River, where possession opens the third Saturday of June (June 20, 2026).
The possession season runs through December 31 on most waters. On Lake Michigan, within one-half mile of the following islands of the Beaver Island Archipelago — Beaver, Garden, High, and Hog in Charlevoix County — the possession season is July 1 through December 31, and bass CIR fishing is open all year.
Important Note: Lake St. Clair and the connecting waters — the St. Clair River and Detroit River — have a bass possession opener that is nearly four weeks later than the rest of the state. Tournament anglers have been disqualified for possessing bass on these waters before the third Saturday of June, even during catch-and-release events. If you are fishing St. Clair in late May or early June, release immediately.
You can check bass fishing season dates in Michigan for a full breakdown of opener timing, spawn windows, and the best times to target each species throughout the year. For comparison, you may also find it useful to review bass fishing season in Indiana or bass fishing season in nearby states if you fish near state borders.
Size Limits for Bass in Michigan
The minimum size limit is 14 inches for both largemouth and smallmouth bass, with a daily bag limit of 5 in any combination. This 14-inch floor applies across the vast majority of Michigan’s inland waters and Great Lakes waters as the statewide default.
That means you can keep up to five bass per day total — whether that is five largemouth, five smallmouth, or any mix of the two — as long as each fish measures at least 14 inches. Fish that do not meet the 14-inch minimum must be returned to the water immediately.
| Water Body | Minimum Size Limit | Notes |
|---|---|---|
| Most inland lakes and rivers (statewide) | 14 inches | Applies to both largemouth and smallmouth |
| Craig Lake State Park (Houghton Co.) | All bass must be released | Artificial lures only; no bass possession |
| Lake of the Clouds (Carp Lake) | No smallmouth possession | Artificial lures only; no live or dead bait |
| Beaver Island Archipelago (L. Michigan) | 14 inches (standard) | Possession season July 1 – Dec. 31 only |
Some individual lakes and water bodies have different regulations that override the statewide defaults. The general table provides statewide regulations for listed species; however, there are many waters in the state that have fishing regulations which differ from those in the table. Always check county-specific exceptions in the current Michigan Fishing Regulations guide before fishing a new body of water.
Pro Tip: Carry a measuring board in your boat. Conservation officers measure fish when they conduct checks, and a fish that looks close to 14 inches in hand may fall short on a flat surface. When in doubt, release it.
Daily Bag Limits for Bass in Michigan
Michigan keeps its statewide bass bag limit straightforward for most waters. The general daily creel limit is 5 fish in any combination, with a 14-inch minimum size limit. This combined limit means largemouth and smallmouth count together toward your five-fish daily total — there is no separate sub-limit for each species under the statewide default.
The bag limit applies only during the possession season. During the catch-and-immediate-release season, you are not permitted to retain any bass regardless of size, so the bag limit is effectively zero outside the possession window.
- Statewide default bag limit: 5 bass per day (largemouth and smallmouth combined)
- Minimum size to keep: 14 inches for each fish
- Possession limit: Typically equal to the daily bag limit
- Special waters: Some lakes require all bass to be released regardless of size (e.g., Craig Lake State Park)
The lakes of Craig Lake State Park — including Clair, Craig, Crooked, Keewaydin, Nelligan, Teddy, and Thomas Lakes — require artificial lures only, and Northern Pike, Muskellunge, Largemouth Bass, and Smallmouth Bass must be released, with a minimum size on Walleye of 15 inches and a possession limit of 2 Walleye; otherwise, all general rules apply.
If you fish waters near the Michigan-Wisconsin border, note that the Michigan-Wisconsin Boundary Waters section of the regulations (pages 24–25 of the 2026 guide) may carry different limits. Always verify the specific rules for any boundary water before keeping fish.
Catch-and-Release Rules and Special Regulation Waters in Michigan
Michigan’s catch-and-immediate-release policy is one of the most angler-friendly features of the state’s bass regulations. Catch-and-immediate-release fishing for bass is allowed all year on all waters, unless otherwise closed to fishing. All bass caught must be immediately returned to the water.
The phrase “immediate release” is legally significant in Michigan. Many anglers assume “catch-and-release” means they can hold fish in a livewell during the closed possession season. In Michigan, the law requires immediate release — no livewell time, no photos with fish in hand for extended periods. Keep it simple: unhook and release.
Special regulation waters impose additional restrictions beyond the statewide defaults. Here are some notable examples:
- Craig Lake State Park: Artificial lures only; Northern Pike, Muskellunge, Largemouth Bass, and Smallmouth Bass must be released.
- Lake of the Clouds: Fishing is restricted to artificial lures only. It is unlawful to use or possess live bait, dead bait, or organic or processed food at any time on the shore or water. No spearing and no possession of Smallmouth Bass.
- Beaver Island Archipelago (L. Michigan): Within one-half mile of Beaver, Garden, High, and Hog islands, the possession season for Largemouth and Smallmouth Bass is July 1 through December 31, and bass catch-and-immediate-release is open all year.
There are regulations requiring all bass and Walleye tournaments and Muskellunge contests to be registered. If you are planning or participating in a tournament during the season, make sure the event is properly registered with the Michigan DNR.
For anglers who also fish other states, it is worth comparing how Michigan’s approach differs. See how bass fishing regulations in Kentucky handle catch-and-release rules, or review bass fishing season in Iowa for a neighboring state’s approach.
Legal Gear and Bait Restrictions for Bass in Michigan
Michigan’s general gear rules for bass fishing are relatively permissive on most waters, but a number of specific water bodies carry restrictions that you need to know before you rig up.
Michigan generally allows fishing with up to two lines simultaneously. This applies to most standard hook-and-line fishing situations. Beyond that baseline, the following restrictions are worth noting:
- Artificial lures only waters: Certain lakes — including Craig Lake State Park waters and Lake of the Clouds — prohibit live bait, dead bait, and organic or processed food entirely.
- Single-pointed hook restrictions: From November 1 through November 30, it is unlawful to use other than one single-pointed, unweighted hook measuring one-half inch or less from point to shank at the port of Grand Haven. Similar restrictions apply at the ports of Muskegon and Whitehall/Montague during the same period.
- Spearfishing: Underwater spearfishing opportunities have expanded to additional Great Lakes waters, though some areas remain excluded. Anglers no longer need to submit monthly reports for this activity, but they are still required to obtain a free spearfishing license.
- Bead clarification (2026): The department provided clarification on equipment used for trout and salmon — a bead used on a hook, or attached to the line no more than 4 inches above a single-pointed hook, is now officially defined as an artificial lure.
Common Mistake: Anglers fishing waters labeled “artificial lures only” sometimes bring live bait rigs onto the water without realizing the restriction. Check the county-specific exceptions in the 2026 Michigan Fishing Regulations guide (pages 28–31) before packing your tackle box for a new destination.
For bass specifically, there are no statewide restrictions on lure type, hook style, or bait on most waters. You can use soft plastics, crankbaits, spinnerbaits, live bait, or any other legal method as long as the water body you’re fishing does not carry a special gear restriction. Always verify the rules for your specific destination in the current regulations guide.
Anglers curious about how gear rules compare elsewhere can review bass fishing regulations in Texas or bass fishing season in Florida for contrast.
Bass Fishing License Requirements in Michigan
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.
All anglers 17 years of age and older must purchase a fishing license. Those under 17 may fish without a license but must follow all fishing rules and regulations.
For the 2026 regulation year, the 2026 fishing licenses are available for purchase and are valid through March 31, 2027. License options and fees are as follows:
| License Type | Who It Covers | Cost (as of March 2026) |
|---|---|---|
| Annual Resident | Michigan residents, age 17+ | $26 + $1 surcharge |
| Annual Nonresident | Out-of-state anglers, age 17+ | $76 + $1 surcharge |
| Senior Annual Resident | Michigan residents, age 65+, or legally blind | $11 + $1 surcharge |
| Daily License | Residents and nonresidents, age 17+ (valid 24 hours) | $10 per day |
| Youth License (optional) | Anglers age 16 and younger | $2 |
Anglers can purchase an annual fishing license at $26 for Michigan residents or $76 for nonresidents (both carry an additional $1 surcharge), a senior annual fishing license at $11 for Michigan residents 65 and older or residents who are legally blind (with additional $1 surcharge), and a daily fishing license at $10 per day for Michigan residents and nonresidents 17 and older (valid for 24 hours).
Fishing license fees are waived for Michigan residents who are veterans with 100% disability or active-duty military, and for individuals who have a developmental disability as defined in section 100a of the mental health code. U.S. Military Personnel: Fishing license fees are waived for full-time, federal, active-duty U.S. military members stationed in Michigan as well.
Pro Tip: Purchase your license through the Michigan DNR Hunt Fish app so you always have it accessible on your phone. You will not need to carry a paper license — your digital license is legally valid on the water.
If you are 17 or older and fishing public waters, you need a license even if you release everything. There is no exemption for catch-and-release-only fishing. A valid license is required any time you are fishing, regardless of whether you intend to keep fish.
For comparison, see how license requirements stack up in other states: bass fishing regulations in Mississippi, bass fishing season in South Carolina, and bass fishing season in Alabama each have their own licensing structures worth reviewing if you travel to fish.
