Bass fishing in Indiana draws anglers to everything from glacial natural lakes in the north to flood-control reservoirs in the south — and the regulations governing those waters are not one-size-fits-all. Whether you are chasing largemouth in a weedy reservoir or working a rocky river for smallmouth, the rules you follow can vary significantly depending on where you wet a line.
Understanding Indiana’s bass fishing regulations before you head out keeps you on the right side of the law and helps protect the fisheries that make the Hoosier State worth fishing in the first place. This guide walks you through every key regulation — species, seasons, size limits, bag limits, special waters, gear rules, and license requirements — based on the 2026 Indiana DNR Fishing Regulations Guide.
Important Note: Regulations can change and vary by specific water body. Always verify current rules with the official Indiana DNR Fishing Guide and Regulations before your trip.
Bass Species Covered by Fishing Regulations in Indiana
Indiana’s bass regulations cover black bass collectively — largemouth, smallmouth, and spotted bass. All three species fall under the same statewide framework, though rules can differ between lakes, reservoirs, rivers, and streams.
Largemouth bass rule the warm, weedy waters of reservoirs and lakes, while smallmouth bass prefer the rocky, cooler flows of rivers and streams. Spotted bass round out the trio, often hanging in deeper waters. Each species plays a distinct ecological role, and the DNR’s regulations reflect the different harvest pressures each population faces.
The majority of largemouth in Indiana waterbodies fall under three statewide black bass regulations; however, there are special regulations on a select group of waterbodies. In fact, approximately one-third of all Indiana anglers target largemouth. Smallmouth bass are equally popular, particularly among river anglers who specifically sought protections for the species through the state’s rule enhancement process.
Key Insight: All three black bass species — largemouth, smallmouth, and spotted — count together toward the same combined daily bag limit in Indiana.
Bass Fishing Season Dates and Closures in Indiana
Bass fishing in Indiana is open year-round. There is no closed season for largemouth, smallmouth, or spotted bass on the vast majority of Indiana’s public waters, which gives you the flexibility to fish whenever conditions suit you.
Indiana has a fishing schedule that is open all year round. You can wet a line whenever the mood strikes because most species don’t have closed seasons. That said, the absence of a closed season does not mean all rules stay the same throughout the year — size limits and special water designations still apply regardless of the month.
Seasonal patterns still matter for success. Largemouth begin spawning in the spring after the water temperature has reached approximately 65°F. Spring fishing from April through May tends to be the most productive period, when bass move shallow and become easier to locate. For a closer look at how seasonal timing affects your approach, see bass fishing season in Indiana for a detailed breakdown by month.
Size Limits for Bass in Indiana
Indiana uses different size limit frameworks depending on whether you are fishing lakes and reservoirs or rivers and streams. Knowing which set of rules applies to your specific water is essential.
Lakes and Reservoirs
The minimum size limit is 14 inches statewide for lakes and reservoirs, though some lakes have an 18-inch minimum. The 14-inch statewide standard applies to the overwhelming majority of Indiana’s inland lakes and impoundments.
One notable exception is Cecil M. Harden Lake (Raccoon Lake), which carries an 18-inch minimum — this produces some of the biggest bass in Indiana. Always check the DNR’s water-specific regulation tables before fishing a new lake, since individual impoundments can carry rules that differ from the statewide default.
Rivers and Streams
With a few exceptions, a person catching black bass from a river or stream may keep only those fish that are under 12 inches or over 15 inches long. The daily bag limit for black bass is five fish singly or in aggregate. No more than two can be over 15 inches.
The protection for black bass that are 12 to 15 inches long is intended to limit harvest of these bass that have the highest reproductive potential. Anglers can keep black bass that are less than 12 inches in length and over 15 inches in length in accordance with the bag limit.
Ohio River and Border Counties
Rivers and streams in counties bordering the Ohio River still have a 12-inch minimum size limit, with an aggregate bag limit of five black bass. Those counties are Clark, Crawford, Dearborn, Floyd, Harrison, Jefferson, Ohio, Perry, Posey, Spencer, Switzerland, Vanderburgh, and Warrick.
The size limit on the Ohio River mainstream (not bays and tributaries) is 12 inches for black bass with a daily bag limit of 6. The Blue River in Crawford, Harrison, and Washington counties still has a 12- to 15-inch slot limit and an aggregate bag limit of five black bass, with no more than two being more than 15 inches.
| Water Type | Minimum Size | Slot / Special Rule | Daily Bag Limit |
|---|---|---|---|
| Statewide lakes and reservoirs | 14 inches | None (standard) | 5 combined |
| Cecil M. Harden Lake (Raccoon Lake) | 18 inches | Enhanced minimum | 5 combined |
| Rivers and streams (general) | Under 12″ or over 15″ | 12–15″ protected slot; max 2 over 15″ | 5 combined |
| Ohio River border county rivers/streams | 12 inches | None | 5 combined |
| Ohio River mainstream | 12 inches | None | 6 combined |
| Blue River (Crawford, Harrison, Washington counties) | Under 12″ or over 15″ | 12–15″ protected slot; max 2 over 15″ | 5 combined |
Daily Bag Limits for Bass in Indiana
The daily bag limit for largemouth and smallmouth bass combined is 5 fish. This combined limit applies to all three black bass species — largemouth, smallmouth, and spotted bass — meaning your total harvest across all three species cannot exceed five fish per day on most Indiana waters.
Possession limit is 10 bass (two daily limits). If you are on a multi-day trip and keeping fish, you may not possess more than two days’ worth of bass at any one time.
There are specific exceptions to the standard five-fish daily limit. At certain waters, the limit is 2 largemouth bass per day, and the largemouth bass must be at least 18 inches long. The Ohio River mainstream carries a higher daily bag limit of six combined black bass, as noted above. Always confirm the specific limit for the water you plan to fish before heading out.
Pro Tip: When fishing multiple water bodies in the same day — for example, a lake in the morning and a river in the afternoon — the daily bag limit is cumulative across your entire day of fishing, not per water body. Keep a running count of what you have already harvested.
Catch-and-Release Rules and Special Regulation Waters in Indiana
Several DNR properties have catch-and-release-only bass regulations — check signage at the access point. These designations are typically found on smaller managed impoundments and are intended to build trophy bass populations by eliminating harvest pressure entirely.
Many Indiana lakes have special bass regulations. For example, some northern lakes have slot limits to protect breeding populations. Slot limits protect fish in a specific size range — typically those with the highest reproductive value — while still allowing harvest of smaller and larger fish within the daily bag limit.
Tournament anglers face additional rules on DNR-managed waters. Tournament anglers must ensure weigh-in fish are alive and must be released into the body of water where caught. Dead fish penalties apply per tournament rules. Additionally, fishing tournaments on DNR properties with 15 or more watercraft are required to obtain a fishing tournament permit.
One important stocking restriction applies statewide: it is illegal to take any live fish and release it into any public waters without a stocking permit. DNR fisheries biologists approve stocking of fish only after careful consideration of the potential impacts of new fish on the existing habitat and fish populations.

Legal Gear and Bait Restrictions for Bass in Indiana
Indiana’s gear rules for bass fishing are relatively straightforward for most anglers, but a few specific restrictions are worth knowing before you rig up.
Rod and Line Limits
You may not fish with more than three poles or hand lines at a time. Each line may have no more than three single- or multi-pronged hooks, three artificial lures, or a combination of three hooks and artificial lures. A multi-pronged hook or two or more single-pronged hooks used to hold a single bait is considered one hook.
Alabama Rig and Multi-Hook Lures
Indiana DNR regulations state only 3 hooks can be used on an Alabama Rig. This is consistent with the statewide three-hook-per-line rule. If you fish multi-hook umbrella-style rigs, count the total hooks carefully to stay within the legal limit.
Limb Lines and Drop Lines
You may fish with no more than 10 limb lines or drop lines at a time. Each line may have no more than one single- or multi-barbed hook attached to it. Each line must have a readable tag showing the name and address of the user or the user’s DNR-issued Customer ID number. All lines must be checked at least every 24 hours.
It is illegal to use a limb or drop line within 300 yards of a dam structure located on any stream, river, ditch, canal, or reservoir. Limb lines are not allowed on the Ohio River.
Snagging Prohibition
Snagging is the practice of dragging or jerking a hook (or hooks) through the water with the intention of hooking a fish on contact. It is illegal to snag fish from public waters in Indiana, including the Ohio River.
Night Fishing
There are no hour restrictions on fishing in Indiana. You can fish 24 hours a day, 7 days a week. Night fishing is popular for catfish, walleye, and summer bass. Night fishing for bass during summer is legal and widely practiced, particularly on warmer lakes and reservoirs.
Common Mistake: Anglers fishing Lake Michigan and its tributaries face special hook size and barb regulations that differ from inland rules. If your bass trip takes you anywhere near Indiana’s Lake Michigan waters, review those specific gear requirements separately in the DNR guide.
Bass Fishing License Requirements in Indiana
Indiana requires a fishing license for anyone age 18 and older who fishes in public waters. This applies to all methods — rod and reel, fly fishing, bowfishing, trotlines, and bank fishing.
A valid Indiana fishing license is required regardless of whether you keep or release fish. The only exceptions are anglers under 18, Free Fishing Days, and other specific exemptions.
License Fees (2026 Season)
The 2026 license year runs April 1, 2026, through March 31, 2027. The following fees apply for the current license year:
| License Type | Cost |
|---|---|
| Resident annual fishing license | $23 |
| Non-resident annual fishing license | $60 |
| Non-resident 7-day license | $35 |
| Non-resident 1-day license | $15 (includes trout/salmon stamp) |
| Senior annual fishing license (residents 64+) | $3 |
| Trout/Salmon Stamp (add-on) | $11 |
| DAV annual hunting and fishing license | $2.75 |
You do NOT need the trout/salmon stamp for warmwater species like bass, catfish, crappie, or bluegill — even if you’re fishing the same water where trout are present. For most bass anglers, a standard resident or non-resident fishing license is all you need.
License Exemptions
Children under 18 — regardless of residency — do not need a fishing license in Indiana. They must still follow all bag limits, size limits, and regulations.
Additional exemptions include: residents of a state-owned mental rehabilitation facility; residents of any licensed health care facility in Indiana taking part in a supervised fishing activity sponsored by the facility; and residents who have a developmental disability as defined by IC 12-7-2-61.
Resident owners of Indiana farmland, resident lessees of Indiana farmland who farm that land, and the spouses and children living with them while fishing on the farmland they own or lease are also exempt. This exemption does not apply to land owned by a business, corporation, or partnership unless the shareholders, partners, members, or owners are composed solely of the members of an immediate family.
Ohio River Border Water Note
If you hold a Kentucky fishing license, it’s valid on the entire main-stem Ohio River thanks to the reciprocal agreement. You do NOT need an Indiana license for the Ohio River — but you do need one for any Indiana tributaries, embayments, or inland waters. Anglers fishing from neighboring states should also compare regulations — see Ohio bass regulations and Kentucky bass regulations if you fish border waters regularly.

Where to Find Current Bass Regulations in Indiana
The 2026 Indiana DNR Fishing Regulations Guide is available through eRegulations. It provides a summary of Indiana fishing regulations and is updated to reflect any corrections or changes throughout the year. This is the most accessible and up-to-date version of the official rules.
The official starting point is the Indiana DNR Fish and Wildlife Fishing Guide and Regulations page, which links directly to the current eRegulations guide. If you need complete versions of Indiana rules and regulations for fishing, they can be found in Indiana Code or in Indiana Administrative Code Title 312. Any corrections or updates to information published in the guide will be made to the online version.
Check length and slot rules — many lakes, rivers, and bays have special tables beyond statewide defaults. Review 2026 summaries and any emergency orders (closures, health notices, gear rules) before you go.

This guide is not intended to be a complete digest of regulations. If you need complete versions of Indiana rules and regulations for fishing, they can be found in Indiana Code or in Indiana Administrative Code Title 312.
If you fish other states in the region, the rules can vary considerably. You can review regulations for neighboring states including Michigan, Iowa, and Illinois to compare frameworks. Anglers who travel farther afield can also check guides for states like Texas, Florida, and Alabama — all of which have their own distinct bass regulation systems.
Pro Tip: Water-specific regulation tables in the DNR guide are updated annually. Even if you have fished a particular lake or river for years, it is worth scanning the special regulations table each season to catch any changes to size limits, bag limits, or gear restrictions on that specific water body.
Indiana’s bass fisheries are well-managed and productive, but that quality depends on anglers following the rules. A quick review of the current DNR regulations guide before each trip is the single most effective step you can take to stay legal, protect the resource, and keep Indiana bass fishing strong for years to come.
