Fly Fishing Regulations in Indiana: What Every Angler Needs to Know
May 26, 2026
Fly fishing in Indiana rewards anglers who do their homework before they ever reach the water. From stocked trout streams in Elkhart County to Lake Michigan tributaries carrying steelhead, the Hoosier State offers more fly fishing opportunity than most people expect — but each fishery comes with its own set of rules.
Whether you are wading a designated catch-and-release stream or casting dries on a stocked inland river, understanding Indiana’s fly fishing regulations keeps you legal, protects the resource, and improves the experience for every angler who follows you downstream. This guide walks you through every major regulatory category you need to know before you rig up.
Important Note: This article is for informational purposes only and is not a substitute for the official Indiana DNR Fishing Regulations Guide. Always verify current rules with the Indiana DNR before fishing, as regulations are subject to change.
Fly 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. There is no separate fly fishing license; the standard sport fishing license covers all legal methods, including the fly rod.
As of the 2026 license year, a resident annual fishing permit costs $23, while non-residents pay $60 for an annual permit. The 2026 license year runs April 1, 2026 through March 31, 2027. If you plan to target trout or salmon on any Indiana public water, you need an additional stamp on top of your base license. If you fish for trout or salmon in Indiana — including Lake Michigan — you need an Indiana trout/salmon stamp ($11) in addition to your regular fishing license.
Short-term options are available for visiting anglers. One-day licenses are $10 (resident) or $15 (non-resident) and include the trout/salmon stamp. That makes the one-day non-resident option a practical choice for a quick out-of-state trip to a stocked trout stream.
- Resident annual license: $23
- Non-resident annual license: $60
- One-day license (resident): $10 (includes trout/salmon stamp)
- One-day license (non-resident): $15 (includes trout/salmon stamp)
- Trout/Salmon Stamp (add-on): $11
A licensee must hold an ink-signed copy of a license while fishing. Signed electronic copies are also acceptable. You must present the license to an Indiana Conservation Officer (or any other authorized law enforcement official) upon request.
Several groups are exempt from the license requirement. A fishing license and trout/salmon stamp are not required for Indiana residents born before April 1, 1943 (who should carry valid Indiana ID to verify age and residency), residents and nonresidents under age 18, and residents who are legally blind. Fishing in a private pond that does not allow fish entry from or exit to public waters is also exempt, though an angler must have permission from the property owner to fish in that pond.
For a full breakdown of Indiana license types, fees, and purchase options, see our guide to fishing license requirements in Indiana. You can purchase your license online through GoOutdoorsIN.com, at more than 500 authorized retailers across the state, over the phone, or by mail.
Pro Tip: Buy your annual license on or after April 1 to get the full license year running through March 31 of the following year. Purchasing in late March means you pay full price for just a few days of coverage.
What Counts as Fly Fishing Gear Under Indiana Law
Indiana fishing regulations do not define “fly fishing” as a separate legal category in the way some western states do. Instead, the DNR regulates gear through rules about hooks, lines, and legal methods. Understanding those rules tells you exactly what fly fishing tackle is and is not permitted.
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. For fly anglers, this means your standard single-fly setup is well within the rules, and tandem or dropper rigs are also permitted as long as the total hook count does not exceed three per line.
Flies are classified as artificial lures under Indiana law. An individual may use artificial lures and artificial flies. Fishing with live or natural baits, food products, or chemical attractants is prohibited on certain designated waters — most notably the catch-and-release streams in Elkhart County discussed later in this article. On general public waters, however, natural bait is permitted alongside artificial flies unless a specific water body carries a gear restriction.
Hook size rules matter on Lake Michigan and its tributaries. Special hook size and barb regulations apply to Lake Michigan and its tributaries. Single hooks, including those on artificial lures, shall not exceed ½ inch from point to shank. Double and treble hooks on artificial lures shall not exceed 3/8 inch from point to shank. If you are fishing streamers or wet flies on a Lake Michigan tributary during a steelhead run, check that your hook dimensions comply with those specific limits.
Fly reels, fly lines, and leaders are not separately regulated beyond the general requirement that each line carry no more than three hooks or lures. For a deeper look at gear options, explore the different types of fishing lines and types of fishing reels used across various methods.
Fly Fishing Only Waters in Indiana
Indiana does not maintain a large network of fly-fishing-only streams in the way that states like Colorado or Wyoming do. However, the DNR has designated specific stretches of water in Elkhart County where only artificial lures or flies may be used — making them the closest equivalent to dedicated fly fishing water in the state.
The following three streams in Elkhart County (totaling 2.8 miles) are designated as year-round “catch-and-release only” and “artificial lures or flies only” trout fishing areas: Little Elkhart River from CR 43 downstream to CR 16, except for waters along Riverbend Park from CR 16 upstream to the pedestrian footbridge; Solomon Creek from CR 33 downstream to the Elkhart River; and Cobus Creek from Old U.S. 20 downstream to the St. Joseph River.
These three Elkhart County streams are the most important designated fly-and-artificial-only waters in Indiana for trout anglers. On all three, natural bait is prohibited year-round, and all fish must be released. They are stocked with trout and managed specifically to maintain a quality catch-and-release fishery.
Outside of these designated stretches, most Indiana public waters allow any legal method including fly fishing. Named lakes and rivers often have special regulations beyond statewide defaults; border waters with neighboring states or provinces may add more rules. Always match the specific water body you plan to fish to the correct regulation table in the current DNR guide before you go.
If you are new to fly fishing and want to understand the full range of tackle and techniques involved, our overview of different types of fishing and the different types of flies for fishing are useful starting points.
Catch-and-Release Rules on Designated Waters in Indiana
Catch-and-release requirements in Indiana apply in two main contexts: time-based seasonal rules that affect all trout streams, and permanent year-round designations on specific named waters.
Catch-and-release applies to all trout streams from Jan. 1 through April 14. A closed season for selected trout streams runs from April 15 to the last Saturday in April (opening day) while DNR staff complete the annual trout stockings. These streams include the Pigeon River and Pigeon Creek in LaGrange County from the Steuben County line to CR 410 E (Troxel’s Bridge).
On the year-round catch-and-release waters, the rules go further. The three Elkhart County streams listed in the previous section require that all trout be released at all times, regardless of season. These stretches are also artificial-lures-or-flies-only, meaning bait fishing is prohibited even during periods when harvest is legal on other streams.
Trout and salmon that are foul-hooked (not caught in the mouth) cannot be kept. They must be released back into the body of water from which they were foul-hooked. This rule applies statewide and is especially relevant for fly anglers swinging streamers or nymphing in fast water where foul-hooking can occur.
Key Insight: The statewide catch-and-release period for trout streams (January 1 through April 14) is a prime window for fly fishing with nymphs and streamers. You can fish legally, but every fish must go back.
On general public waters with no special designation, catch-and-release is voluntary outside of size and bag limit requirements. Anglers are responsible for maintaining fish in a healthy condition. Dead and dying fish cannot be released back into the water. If you choose to practice catch-and-release on non-designated waters, proper handling is both an ethical obligation and, in some circumstances, a legal one.

Barbless Hook Requirements in Indiana
Indiana does not have a statewide barbless hook mandate for fly fishing. Barbless hooks are not mandated but recommended on stocked trout streams. The DNR encourages their use as a best practice for catch-and-release fishing, but barbed hooks remain legal on most Indiana waters.
The exception is Lake Michigan and its tributaries, where specific hook size and barb rules do apply. Special hook size and barb regulations apply to Lake Michigan and its tributaries. If you are fly fishing for steelhead on Trail Creek or the St. Joseph River, review the current Lake Michigan tributary hook regulations in the DNR guide before rigging up, as these rules are more restrictive than those governing inland streams.
Even where barbless hooks are not required by law, many fly anglers fishing Indiana’s catch-and-release waters choose to crimp or file their barbs voluntarily. Barbless hooks make unhooking faster and less damaging to fish, which matters most on high-pressure waters like the Elkhart County streams where every fish is returned.
Pro Tip: Crimping the barb on your fly hooks takes seconds and significantly reduces handling time when releasing fish. On designated catch-and-release waters, faster releases mean healthier fish and a better fishery for everyone.
For context on how other states handle barbless hook requirements — some of which are mandatory — see our guide to trout fishing season in Wyoming, where barbless rules on certain blue-ribbon waters are strictly enforced.
Size Limits, Bag Limits, and Slot Limits in Indiana
Indiana’s size and bag limits for trout vary depending on whether you are fishing inland streams, inland lakes, or Lake Michigan and its tributaries. Fly anglers targeting trout need to know which set of rules governs the specific water they are fishing.
For inland streams, the general trout season runs from the last Saturday in April through December 31. There is no closed season for taking trout from inland lakes. The opening day of trout season for inland streams is 6 a.m. local time on the last Saturday in April. The season runs through Dec. 31.
On Lake Michigan, the daily bag limit for trout and salmon is five fish, with specific sub-limits by species. Not more than five trout or salmon are taken per day, of which not more than one may be a brown trout.
Brown trout carry special size restrictions on certain named waters. There is an 18-inch minimum size limit at Oliver, Olin, and Martin lakes in LaGrange County, and the Brookville Lake tailwater in Franklin County. If you are targeting brown trout at any of these locations, any fish under 18 inches must be released regardless of the general statewide limit.
For warmwater species that fly anglers often pursue — bass, bluegill, and crappie — the following statewide limits apply as of the 2026 regulations:
| Species | Minimum Size | Daily Bag Limit |
|---|---|---|
| Largemouth/Smallmouth Bass | 14 inches | 5 combined |
| Walleye/Sauger | 14 inches (south of SR 26) / 16 inches (north) | 6 per day |
| Muskellunge | 36 inches | 1 per day |
| Channel Catfish | No statewide minimum | 10 per day |
| Crappie | No statewide minimum | 10 per day (25 combined panfish) |
Always verify special regulation waters before fishing — some lakes and reservoirs have different rules than statewide standards. For example, on Fidler Pond (Elkhart County), the largemouth bass limit drops to 2 per day with an 18-inch minimum, and combined bluegill/crappie/redear sunfish is limited to 15 per day.
Possession limits also apply. The possession limit is two times the daily bag limit for most species. However, this does not apply to fish that have already been processed and stored at your primary residence.
Fly anglers chasing bass in Indiana will want to review the bass fishing season in Indiana for additional context on open seasons and water-specific rules.
Special Regulation Waters and Blue-Ribbon Fisheries in Indiana
Indiana does not use the term “blue-ribbon fishery” in its official regulations the way Montana or Wyoming do, but the state does designate specific waters with enhanced rules designed to protect quality fishing. The Elkhart County catch-and-release streams are the clearest example, but other waters carry notable special regulations worth knowing.
The Pigeon River system in LaGrange County is one of Indiana’s most significant trout destinations. A closed season for selected trout streams runs from April 15 to the last Saturday in April while DNR staff complete the annual trout stockings. These streams include the Pigeon River and Pigeon Creek in LaGrange County from the Steuben County line to CR 410 E (Troxel’s Bridge). Outside the closed window, the Pigeon River is open to general trout regulations, making it a popular destination for fly anglers in northern Indiana.
The Brookville Lake tailwater in Franklin County carries a special brown trout size limit. As noted above, an 18-inch minimum applies to brown trout taken from that tailwater, making it a de facto quality fishery even without a formal blue-ribbon designation. Tailwater fisheries like Brookville tend to hold larger, more selective trout that respond well to fly presentations.
Lake Michigan tributaries — particularly Trail Creek near Michigan City and the St. Joseph River near South Bend — function as Indiana’s most prominent wild fisheries for fly anglers targeting steelhead and brown trout. Lake Michigan salmonid fishing on Trail Creek and the St. Joseph River requires a Trout/Salmon Stamp. Lake Michigan, the Ohio River, and Indiana-Illinois boundary waters of the Wabash River have special regulations. Review the Lake Michigan tributary section of the DNR guide carefully before fishing these waters, as hook size rules, seasonal windows, and gear restrictions differ from inland stream rules.
Common Mistake: Anglers who fish Lake Michigan tributaries without a Trout/Salmon Stamp are in violation even if they hold a valid annual fishing license. The stamp is a separate required add-on whenever you target trout or salmon on any Indiana public water.
Gear restrictions (bait, hooks, tackle) where they apply, and special rules for WMAs, community fishing waters, trophy waters, and border waters are published in the annual DNR summary. For any water body carrying special regulations, always read the specific table in the current regulations guide rather than relying on general statewide defaults.

Where to Find Current Fly Fishing Regulations in Indiana
Indiana publishes its official fishing regulations through the DNR Division of Fish, Wildlife and Nature Preserves. The most reliable way to access current rules is directly through official state channels, which are updated annually and reflect any emergency orders or mid-year changes.
The Indiana Fishing Regulations Guide is available on eRegulations, a third-party online service. The eRegulations website has different privacy and security policies and contains advertising. The guide at eregulations.com/indiana/fishing is the digital version of the official DNR publication and is searchable by species, water body, and regulation type.
The official Indiana DNR page at in.gov/dnr/fish-and-wildlife/fishing is the authoritative source for licenses, regulation updates, and emergency closures. Any corrections or updates to information published in the printed guide will be made to the online version. This means the online guide may be more current than any printed copy you pick up at a retailer.
Licenses and regulation access are now managed through the DNR’s Activity Hub system. The Division of Fish, Wildlife and Nature Preserves’ Activity Hub completed its first year of serving hunters and anglers after replacing the previous license system in December 2024. Logging in through Access Indiana gives access to license sales, game check-in, HIP registration, donations, and other core functions. For step-by-step guidance, FAQs, and troubleshooting tips, visit the Go Outdoors Indiana Help and Support page.
For questions about specific waters or regulations, you can contact the DNR Customer Service Center directly. Customers who have questions regarding their accounts should call the DNR Customer Service Center at (317) 232-4200 or (877) 463-6367, or email. Hours of operation are 8:30 a.m. to 4 p.m. ET, Monday through Friday.
Conservation officers enforce the official published regulations — not articles or forum posts. When in doubt, go to the source. Regulations change from year to year, and what was legal last season may not be legal now.
