What the Peshtigo River offers

The Peshtigo River is a fast-moving, rocky stream in northeastern Wisconsin that holds walleye, smallmouth bass, and northern pike across roughly 60 miles of fishable water. The river runs from the Peshtigo Flowage near Wausaukee south to Green Bay, dropping through a mix of rapids, pools, and deeper sections that create distinct fishing zones. The current is strong enough that you will feel it in a boat, and the rocky bottom means snags are real — this is not a lake, and it demands different tactics than the calmer Wisconsin rivers to the west.

The Peshtigo is known for walleye in spring and fall, when fish move into the faster water to feed. Smallmouth bass thrive year-round in the rocky structure, and pike show up in deeper pools and backwater areas. The river is accessible at multiple public landings, and much of it is open to fishing without special permission, though some sections run through private land. The water can be cold and the current strong, so this river suits anglers with some experience reading current and managing a boat in moving water.

Key Takeaways

  • The Peshtigo holds walleye, smallmouth bass, and northern pike across 60 miles of river, with the strongest fishing in spring and fall when walleye are active.
  • The river's rocky bottom and fast current create good habitat but also mean snags and the need for careful boat handling and anchor placement.
  • Public boat landings exist at Peshtigo, Oconto, and several points in between, with parking and access managed by the county or town.
  • Wisconsin fishing regulations apply: walleye have a daily bag limit and size minimum that vary by season, and you need a current Wisconsin fishing license.
  • Summer water levels can drop and expose rocks, making spring and fall the safest and most productive seasons for most anglers.

Walleye fishing in spring and fall

Walleye move into the Peshtigo's faster sections during spring (April through May) and fall (September through October) to feed on baitfish pushed by the current. The best zones are the deeper pools below rapids and the transition areas where fast water slows. Jigs tipped with live minnows or soft plastics work well, as do crankbaits that mimic the natural forage. Fish early morning and late evening when light is low — walleye in moving water are less shy than in lakes, but they still prefer dim conditions.

Summer walleye fishing is slower because fish retreat to the deepest, coolest pools, and the river's current can make them less aggressive. Winter is possible but requires caution: ice forms unevenly on moving water, and the current keeps some sections open. Most anglers focus on spring and fall, when the water temperature and fish behavior align with the river's character.

The Peshtigo's walleye population is not as dense as some Wisconsin lakes, so expect to work for your catch. Patience and reading the water — understanding where current breaks and where fish hold — matter more than sheer volume of casts.

Smallmouth bass and pike in rocky structure

Smallmouth bass are the Peshtigo's most reliable fish. They live in and around the rocky structure year-round, feeding on crayfish and small baitfish. Spring and fall are productive, but summer is good too if you fish early and late in the day. Tube jigs, small crankbaits, and soft plastics in natural colors work well. The rocks hold fish, so cast tight to structure and expect to lose some lures — bring extras.

Northern pike inhabit the deeper pools and slower backwater sections, particularly where the river widens or where tributaries enter. Pike are less predictable than walleye or smallmouth, but they can be large and aggressive. Live baitfish or large pike-pattern lures work best. The pike population is smaller than the smallmouth population, so do not expect frequent hookups, but when you connect, the fish are often worth the wait.

Access points and boat launch details

The Peshtigo has several public boat landings managed by Oconto County or the towns along the river. The main launch is at Peshtigo, on the lower river near the mouth at Green Bay — this is the most developed facility with parking and a paved ramp. Upstream, there are smaller landings at Oconto and at several points between, though some are basic gravel ramps with limited parking. Check with the Oconto County Parks Department or the town clerk before launching at smaller ramps, as maintenance and access can change.

The river is navigable by small to medium motorboats and canoes, though the current and rocks demand attention. In spring, water levels are higher and navigation is easier. By mid-summer, water levels drop and rocks become hazards — many anglers switch to canoes or drift boats in summer, or simply avoid the river until fall. Wading is possible in some sections, but the current is strong and the rocks are slippery; wear a life jacket and use a wading staff if you wade.

Regulations and licensing

Wisconsin fishing regulations apply to the Peshtigo. You must have a current Wisconsin fishing license, available online through the Wisconsin Department of Natural Resources (DNR) website or at sporting goods retailers. Licenses are sold as daily, annual, or multi-year options for residents and non-residents.

Walleye on the Peshtigo have a daily bag limit of five fish and a minimum size of 15 inches (check the current DNR regulations, as these can change). Smallmouth bass have a daily bag limit of five fish with a 12-inch minimum. Northern pike have a daily bag limit of one fish with a 24-inch minimum. Catch-and-release is always an option and does not count toward bag limits. The DNR publishes a current fishing guide for Wisconsin that lists all species, limits, and seasonal closures — download it before you fish.

Seasonal conditions and water levels

Spring (April through May) brings high water from snowmelt and rain, making the Peshtigo fast and powerful. This is excellent for walleye and for anglers comfortable in moving water. The current is strong, so anchor carefully and use a heavy anchor or drift if anchoring is not safe.

Summer (June through August) sees water levels drop as runoff decreases. Rocks that were underwater in spring become visible and hazardous. The river is still fishable, but navigation requires care. Water temperature rises, and fish move to deeper, cooler sections. Fishing is slower, but early morning and evening can still produce.

Fall (September through October) brings cooler water and renewed walleye activity. Water levels are moderate, and the river is at its most balanced for fishing. This is many anglers' favorite season on the Peshtigo.

Winter is possible but challenging. Ice forms on slower sections, but the current keeps some areas open. Check ice conditions with local anglers before attempting winter fishing, and never assume ice is safe on moving water.

What to bring and how to fish the current

Bring a heavy anchor or a drift sock if you plan to fish from a boat — the current will push you if you are not anchored. Bring extra lures and jigs, as the rocky bottom claims tackle. A depth finder helps you locate deeper pools and structure. Polarized sunglasses let you see rocks and fish in the clear water. A net is useful for landing fish in current.

Fishing the current means casting upstream or across the current and letting your lure drift naturally, or working it against the current to create action. Fish hold behind rocks and in the slack water on the downstream side of structure — cast there and let the current do the work. Drifting is a common technique: launch upstream, cut the motor, and drift with the current while casting to structure. This covers water efficiently and lets you fish without fighting the current.

Frequently Asked Questions

Can I fish the Peshtigo in winter?

Yes, but with caution. Ice forms on slower sections, but the current keeps some areas open. Check ice conditions with local bait shops or anglers before you go. Never assume ice is safe on moving water — the current can weaken it from below. Winter fishing is possible but not the safest or most productive season.

What is the best time of year to fish the Peshtigo?

Spring (April through May) and fall (September through October) are best for walleye and most anglers. Water levels are moderate, temperatures are comfortable, and fish are active. Summer is possible but slower. Winter is challenging and less productive.

Do I need a boat to fish the Peshtigo?

No. You can wade in some sections or fish from shore at the public landings and access points. Wading is possible but the current is strong and rocks are slippery — wear a life jacket and use a wading staff. A boat lets you cover more water and reach deeper pools, but it is not required.

What size fish can I expect to catch?

Walleye typically run 12 to 18 inches, with some larger. Smallmouth bass average 10 to 14 inches, with occasional fish to 16 inches or more. Pike are less common but can be large — 20 to 30 inches is possible. The Peshtigo is not known for trophy fish, but solid, catchable fish are the norm.

Where can I get a Wisconsin fishing license?

Online through the Wisconsin DNR website, or at sporting goods retailers, bait shops, and some grocery stores. Licenses are available as daily, annual, or multi-year options for residents and non-residents. You need a current license before you fish.
