What Southport Marina Offers
Southport Marina sits on the Sturgeon Bay Ship Canal in Door County, Wisconsin, giving anglers access to both the canal itself and nearby Green Bay waters. The facility operates as a public launch point with slips available for rent, and it's one of the few full-service marinas in the area with fuel, repairs, and tackle services on-site. The canal and adjacent waters hold walleye, perch, and smallmouth bass in season, with charter captains operating out of the marina if you don't have your own boat.
The marina's location on the canal means you're fishing in relatively protected water compared to open Green Bay, which matters for smaller boats or anglers who prefer calmer conditions. The canal itself is narrow and busy with commercial traffic, so boat handling and awareness of larger vessels is necessary. Most recreational fishing happens in the wider waters just beyond the canal mouth or in the bays accessible from there.
Key Takeaways
- Southport Marina provides public boat launch access to Sturgeon Bay Ship Canal and Green Bay, with fuel and tackle services available on-site.
- Walleye fishing is strongest in spring and fall; perch and smallmouth bass are present year-round in nearby waters.
- The canal itself is narrow and carries commercial traffic, so most recreational anglers fish the wider bays beyond the canal mouth.
- Wisconsin fishing licenses are required for all anglers 16 and older, and Door County has specific regulations for walleye and perch that change seasonally.
- Charter captains operate from the marina if you want to fish without owning a boat, though advance booking is common during peak season.
Seasons and What Fish Are Biting
Walleye fishing peaks in spring (April through May) and again in fall (September through October), when fish move into shallower water and feed more actively. Summer walleye fishing is possible but slower, as fish move deeper during the day. Perch are present year-round and often provide consistent action, especially in the bays where they school in deeper holes during winter.
Smallmouth bass season runs from mid-May through November in Wisconsin. Early summer and fall produce the best catches. Winter fishing for perch and some walleye continues through February, though ice conditions on the bay side of the canal can make access unpredictable. Spring is the busiest season at the marina, so expect crowded launch ramps and higher slip rental rates if you're planning to stay for several days.
Regulations and Licenses You Need
Wisconsin requires a fishing license for anyone 16 or older. You can purchase a three-day, annual, or lifetime license through the Wisconsin Department of Natural Resources website or at local bait shops near the marina. Non-resident licenses cost more than resident licenses; a three-day non-resident license is the most affordable short-term option if you're visiting.
Door County has specific daily catch limits and size restrictions for walleye and perch that differ from other Wisconsin waters. Walleye have a 15-inch minimum size and a daily limit of five fish. Perch have no size minimum but a daily limit of 25 fish. Smallmouth bass must be 12 inches or larger, with a daily limit of five. These regulations change occasionally, so check the current Wisconsin fishing regulations guide before you fish.
Getting to Southport Marina and Parking
Southport Marina is located at 1015 South Eighth Avenue in Sturgeon Bay, Wisconsin. From Green Bay, take Highway 57 north for about 45 minutes to Sturgeon Bay, then follow local signs to the marina. Parking is available at the facility, though spaces fill quickly during peak season weekends. The marina has a public boat launch with multiple lanes, reducing wait times compared to single-lane launches.
If you're towing a trailer, arrive early in the morning or on weekdays to avoid congestion. The launch ramp is concrete and well-maintained, suitable for boats up to about 25 feet. If you don't have a boat, charter services operate from the marina and can accommodate groups; most charter captains require advance booking, especially from May through September.
Marina Services and What to Bring
Southport Marina offers fuel (gasoline and diesel), pump-out facilities, and basic tackle and bait sales. A small shop on-site stocks live bait, lures, and fishing supplies, though selection is limited compared to larger tackle shops in Sturgeon Bay proper. If you need specialized equipment or a wider range of lures, plan to visit one of the independent tackle shops in town before heading to the marina.
Slip rentals are available by the night, week, or season. Rates vary depending on slip size and season; summer rates are higher than spring and fall. The marina has restroom facilities and a fish cleaning station. Bring your own cooler for keeping fish, sunscreen, and a hat — the canal and bay offer little shade, and sun exposure is intense even on cloudy days.
Nearby Lodging and Food
Sturgeon Bay has motels, bed-and-breakfasts, and vacation rentals within a few miles of the marina. The town itself is small but has restaurants, grocery stores, and gas stations. If you're planning a multi-day fishing trip, booking lodging in advance during summer is important, as rooms fill quickly. Many anglers stay in Sturgeon Bay and drive to the marina each morning rather than renting a slip.
The marina area itself has limited food options, so eat before launching or bring snacks and water. Several restaurants in downtown Sturgeon Bay are within a 10-minute drive and offer casual dining and fish fry options typical of Wisconsin Door County establishments.
Fishing Conditions and What to Expect
Water conditions on the canal are calmer than open Green Bay, but the canal is narrow and commercial ships pass through regularly. If you're launching a smaller boat, stay alert for wake and traffic. The bay waters beyond the canal mouth can be rough on windy days, so check the forecast before heading out. Spring and fall often bring unpredictable weather, so bring rain gear and a life jacket regardless of the season.
The bottom near the marina is mostly sand and silt, with some rocky areas in the bays beyond. Walleye and perch relate to structure — drop-offs, weed lines, and hard bottom — so fish don't concentrate in the shallow canal itself. Most productive fishing happens 1 to 3 miles from the marina in deeper water. If you're new to the area, hiring a charter captain for your first trip is a practical way to learn the productive spots and seasonal patterns.
Frequently Asked Questions
Do I need a boat to fish at Southport Marina?
No. Charter captains operate from the marina and take anglers out daily during the fishing season. You can also fish from shore in some areas near the marina, though boat access reaches more productive water. Advance booking for charters is recommended, especially from May through September.
What's the best time of year to fish here?
Spring (April–May) and fall (September–October) are peak seasons for walleye. Perch fish well year-round. Summer is slower for walleye but still productive for perch and smallmouth bass. Winter perch fishing is possible through February if ice conditions allow access.
Can I rent a slip for just one night?
Yes, Southport Marina offers nightly slip rentals. Rates are higher during summer than spring and fall. Call ahead to confirm availability, especially on weekends during peak season.
Where do I buy a Wisconsin fishing license?
You can purchase a license online through the Wisconsin Department of Natural Resources website, or at local bait and tackle shops in Sturgeon Bay near the marina. Three-day licenses are available for visitors and are the most affordable short-term option.
What should I know about the canal itself?
The Sturgeon Bay Ship Canal is narrow and carries commercial traffic. Most recreational fishing happens in the wider bays beyond the canal mouth, not in the canal itself. Stay alert for larger vessels and their wake if you're launching a small boat.
