What the 3-Day License Covers

Maryland's 3-day resident freshwater fishing license lets you fish in freshwater for three consecutive calendar days. You can use it in any of Maryland's freshwater lakes, rivers, and streams — including reservoirs like Prettyboy and Loch Raven near Baltimore, and the Potomac River sections open to freshwater fishing. The license covers most freshwater species: largemouth and smallmouth bass, catfish, crappie, bluegill, carp, and others.

The license does not cover tidal waters (the Chesapeake Bay and its tidal tributaries) or saltwater fishing. If you plan to fish the Bay or ocean, you need a separate saltwater license. The 3-day license is also not valid for trout in special trout management areas, which require an additional trout stamp.

You must carry the physical license or a printed copy with you while fishing. Maryland does not currently issue digital licenses that you can display on your phone, so print it before you leave home or keep the paper copy in your tackle bag.

Key Takeaways

  • The 3-day license covers three consecutive calendar days of freshwater fishing in lakes, rivers, and streams across Maryland.
  • You can purchase the license online through the Maryland Department of Natural Resources website or at authorized vendors like bait shops and sporting goods stores.
  • The license does not cover tidal waters, saltwater fishing, or trout in special trout management areas — those require separate licenses or stamps.
  • You must carry a printed copy of your license; Maryland does not offer mobile or digital licenses at this time.
  • The cost varies slightly depending on where you buy it, but online purchase is usually the fastest option.

Where to Buy the License

You can purchase a 3-day freshwater license online through the Maryland Department of Natural Resources website (dnr.maryland.gov). The online process takes about five minutes: you provide your name, address, date of birth, and driver's license number, then pay by credit or debit card. You receive a confirmation email with a PDF you can print immediately. Many people buy online the night before or the morning of their fishing trip.

You can also buy the license in person at authorized vendors throughout Maryland. These include bait and tackle shops, sporting goods retailers (like Dick's Sporting Goods and Cabela's), and some Walmart locations. Call ahead to confirm the vendor has 3-day licenses in stock, since smaller shops may not always carry them. In-person purchase is instant — you walk out with a printed license.

A few vendors sell licenses by phone, though this is less common. Check the DNR website for a current list of vendors near you, as the network changes occasionally.

Cost and Payment

The 3-day resident freshwater license costs the same whether you buy it online or in person. The exact price can vary slightly by vendor (some add a small processing fee), but the state fee itself is set by Maryland. Check the DNR website or call the licensing office at 410-260-8DNR (8367) for the current price, as fees are adjusted periodically.

Payment methods depend on where you buy. Online purchases accept credit and debit cards. In-person vendors typically accept cash, card, or both — confirm before you go. There are no refunds once the license is issued, even if you do not use all three days.

Who Needs a License and Who Does Not

Any resident of Maryland age 16 and older must have a freshwater fishing license to fish in freshwater. Residents are defined as people who have lived in Maryland for at least six months or hold a Maryland driver's license or ID card.

You do not need a license if you are under 16, if you are fishing on your own private property with the owner's permission, or if you hold a valid commercial fishing license. Active-duty military members stationed in Maryland may be exempt under certain conditions — contact the DNR to confirm your status.

If you are not a Maryland resident, you need a non-resident license instead. Non-resident 3-day licenses are also available but cost more than resident licenses.

When Your License Is Valid

Your 3-day license is valid for three consecutive calendar days starting on the date you choose. If you buy a license on a Monday, you can fish Monday, Tuesday, and Wednesday. If you buy one on Friday, you can fish Friday, Saturday, and Sunday. The license expires at the end of the third day at 11:59 p.m.

You do not have to use all three days in a row — you can skip a day and come back later. The key is that the license covers a three-day window, not three separate fishing trips. Once the window closes, the license is no longer valid.

There is no "best" time to buy. Purchase whenever it suits your schedule. If you know you are fishing next weekend, buy the license a few days ahead so you have the printed copy ready.

Fishing Regulations You Need to Know

Holding a valid license does not mean you can fish anywhere or catch anything. Maryland has specific rules about where you can fish, what species you can keep, and how many. These rules vary by location and season.

Catch limits (also called creel limits) set how many fish of each species you can keep per day. For example, largemouth bass might have a limit of five fish per day, while catfish might allow 25. Check the current regulations before you fish — limits change and vary by water body.

Size restrictions require that fish meet a minimum length before you can keep them. A largemouth bass might need to be 12 inches; a smallmouth bass 9 inches. You must measure from the mouth to the tail. If a fish is too small, you must release it immediately.

Seasonal closures close certain waters or species to fishing during spawning or recovery periods. Some trout streams are closed to fishing in summer. Some bass waters have seasonal restrictions. Check the DNR website or the current fishing guide before you go.

The Maryland Freshwater Fishing Guide (available free on the DNR website) lists all current regulations by water body. Download it or pick up a printed copy at a vendor. Ignorance of the rules is not a defense if you are checked by a conservation officer.

What to Bring and How to Fish Legally

Carry your printed license with you at all times while fishing. A conservation officer can ask to see it, and you must produce it on demand. Keep it in a waterproof pocket or bag so it does not get soaked.

You also need a fishing rod and reel (or a cane pole), hooks or lures, and a way to measure fish if you plan to keep any. A simple ruler or tape measure works. If you are keeping fish, bring a cooler or stringer to keep them fresh.

Bait (live minnows, worms, crickets) and artificial lures are both legal in freshwater. Some waters restrict certain methods — for example, some trout areas allow only fly fishing or artificial lures. Check the regulations for your specific water.

Frequently Asked Questions

Can I fish the Chesapeake Bay with a 3-day freshwater license?

No. The Bay and its tidal tributaries require a saltwater license, which is separate. The freshwater license is only valid in non-tidal rivers, streams, and lakes. If you are unsure whether a water body is tidal, check the DNR website or call 410-260-8DNR.

What happens if I get caught fishing without a license?

Fishing without a valid license is a violation of Maryland law. Penalties include fines and possible confiscation of your equipment. A conservation officer can stop you at any time to check your license. It is not worth the risk — the license is inexpensive compared to the penalty.

Can I buy a 3-day license if I am visiting Maryland from another state?

No. The 3-day license is for Maryland residents only. If you are visiting, you need a non-resident license. Non-resident 3-day licenses are available at the same vendors and online, but they cost more. You must provide a valid out-of-state ID or driver's license.

Do I need a separate license to fish for trout?

In most Maryland freshwater, your 3-day license covers trout. However, in special trout management areas (like certain sections of the Gunpowder River), you need an additional trout stamp. The stamp is inexpensive and sold at the same vendors. Check the DNR website to see if your target water requires one.

Can I use my 3-day license to fish multiple days if I buy it multiple times?

Yes. You can buy a new 3-day license whenever you want to fish again. There is no limit on how many times you can purchase them. Many people buy a new license each time they plan a fishing trip, especially if they fish frequently.
