What You'll Find at Lock and Dam No. 2

Lock and Dam No. 2 sits just south of Hastings, Minnesota, and creates one of the most reliable walleye and northern pike fisheries on the upper Mississippi. The dam backs water into a pool that stretches several miles upstream, and the current breaks and deep holes around the structure itself hold fish year-round. The lock chamber—where barges pass through—creates a natural gathering point for gamefish because baitfish get disoriented in the turbulence, and predators know it.

The character of this water is different from the open river pools upstream. You're fishing a transition zone where current meets slack water, and that matters for how you approach it. Walleye here respond to live bait and jigs in spring and fall, but summer fishing requires deeper presentations and night work. Northern pike cruise the shallower weed edges and current seams, especially in early season.

Key Takeaways

  • Lock and Dam No. 2 creates a pool with distinct current breaks and deep holes that hold walleye and northern pike throughout the year.
  • Spring and fall walleye fishing is strongest around the dam structure itself, using live bait rigs and jigs in 15 to 25 feet of water.
  • Summer walleye move deeper and feed at night; night fishing with live shiners or crawlers near the dam's discharge produces consistent results.
  • Northern pike relate to shallow weed edges and current seams in the pool, particularly in April and May before summer heat pushes them deeper.
  • Public access is available at Hastings Dam Park on the north side and at several boat launches upstream in the pool.

Spring Walleye Fishing Around the Dam Structure

March through May is when Lock and Dam No. 2 fishes best for walleye. The fish move shallow as water temperature climbs from the 40s into the 50s, and they concentrate around the dam's concrete structure and the current breaks it creates. Fish the face of the dam itself—the downstream side where water pours through the gates—and the slack water pockets immediately adjacent to the current.

Live bait rigs work better than anything else here. Use a slip sinker rig with a size 2 or 3 hook, a small split shot 18 inches above the hook, and a live shiner or fathead minnow 3 to 4 inches long. Cast uptake of the current and let the bait drift naturally into the slack pockets. You'll feel the walleye bite as a solid thump, not a tap. Set the hook hard—these fish often mouth the bait first.

Jigs tipped with live bait also work, especially if you're fishing the deeper holes in the pool itself rather than right at the dam. A 1/4-ounce jig with a 3-inch shiner lets you work the bottom in 15 to 25 feet of water, which is typical depth in the pool. Vertical jigging is more efficient than casting if you're in a boat and can hold position in the current.

Summer and Night Fishing When Daytime Bites Slow

By June, walleye at Lock and Dam No. 2 move deeper and become nocturnal. Daytime fishing is possible but requires patience and deeper presentations. Fish the deepest holes in the pool—some reach 35 to 40 feet—using live bait rigs or jigs. Early morning and late evening produce better results than midday, and cloudy days are more productive than bright sun.

Night fishing is the real opportunity. Fish the dam structure itself after dark, using live shiners or nightcrawlers on slip sinker rigs. The walleye move shallow at night to feed, and the turbulence around the dam attracts baitfish. Fish from the bank at Hastings Dam Park or from a boat if you're comfortable navigating the area in darkness. A headlamp with a red lens helps you see your line and rod tip without spooking fish.

Casting crankbaits and soft plastics at night can also work, particularly if you're targeting the shallower edges of the pool. A 5 to 7-foot crankbait that dives to 8 to 12 feet covers water efficiently and can draw aggressive strikes from walleye that are actively feeding.

Northern Pike in Spring and Early Summer

Northern pike at Lock and Dam No. 2 are aggressive and abundant, especially in April and May. They relate to weed edges and shallow current seams in the pool, where they ambush baitfish. Fish the edges of the main channel where weeds begin to grow, typically in 6 to 12 feet of water. Casting large shiners on quick-strike rigs or using medium-sized crankbaits will draw strikes.

Pike here are not particularly selective. A 6 to 8-inch shiner on a quick-strike rig—a two-hook setup that lets you set the hook immediately when a pike takes the bait—works as well as anything. Cast along the weed line and work the bait slowly. Pike will follow and hit hard. By mid-June, pike move deeper and become less active as water temperature climbs above 70 degrees.

Access Points and Boat Launch Information

Hastings Dam Park, on the north side of the dam, offers public access and a small boat launch. The launch is suitable for small to medium boats and can get crowded on weekends during spring. There is parking, and the park has restrooms. This is the most convenient access if you're fishing from Hastings.

If you want to fish the pool upstream of the dam, several public launches are available in the pool itself. The Vermillion River confluence, a few miles upstream, has access points. These launches put you in calmer water and are good if you want to fish the deeper holes in the pool rather than right at the dam structure.

Bank fishing is also possible at Hastings Dam Park and at various points along the river on public land. The park's bank access is best for night fishing and for anglers without boats.

Seasonal Patterns and Water Level Changes

Water level at Lock and Dam No. 2 is controlled by the lock operations and can fluctuate, especially during high-water periods in spring. These fluctuations affect where fish position themselves. Rising water pushes walleye shallower and can trigger feeding binges. Falling water concentrates fish in the deepest holes and can slow the bite temporarily.

Fall fishing—September through October—mirrors spring in many ways. Walleye move shallow again as water cools, and the bite around the dam structure becomes reliable. Water temperature in the 50s is ideal. Northern pike also become more active in fall, though they're less predictable than in spring.

Winter fishing is possible but requires different tactics. Walleye move to the deepest holes in the pool, and ice fishing with live bait or jigging spoons is the standard approach. The dam area itself is dangerous in winter due to thin ice and current, so focus on the pool upstream.

What Gear and Tackle to Bring

For walleye, a 6 to 6.5-foot medium-action spinning rod with 8 to 10-pound monofilament or braided line is standard. Jigs in 1/4 to 3/8-ounce weights, slip sinker rigs, and live bait are your core tackle. Bring shiners, fatheads, and nightcrawlers in a bait bucket with an aerator.

For northern pike, a 6.5 to 7-foot medium-heavy rod with 12 to 15-pound line handles larger fish and allows you to cast heavier lures. Crankbaits in the 4 to 6-inch range, spinnerbaits, and quick-strike rigs are effective. Pike will test your drag, so make sure it's set properly before you cast.

A fish finder is helpful if you're fishing from a boat, particularly for locating the deeper holes in the pool and identifying structure around the dam. GPS is useful for marking productive spots and returning to them on future trips.

Frequently Asked Questions

Is it safe to fish right at the dam structure?

Yes, if you stay in designated areas and respect the current. The dam face itself is accessible from the bank at Hastings Dam Park. Do not wade into the main current or approach the lock chamber. If you're in a boat, keep clear of the gates and the discharge area where water pours through at high velocity.

What's the best time of day to fish Lock and Dam No. 2?

Spring and fall, early morning and late evening are most productive for walleye. Summer requires night fishing for consistent results. Northern pike bite throughout the day in spring but are most active in early morning and late evening. Cloudy days are better than bright sun year-round.

Do I need a Minnesota fishing license to fish here?

Yes. Minnesota requires a fishing license for anyone 16 and older. You can purchase a license online through the Minnesota Department of Natural Resources website or at most bait and tackle shops in Hastings. A three-day license is available if you're visiting briefly.

Can I fish from the bank, or do I need a boat?

Bank fishing is productive, especially at Hastings Dam Park and for night fishing. A boat gives you access to deeper holes in the pool and more flexibility in positioning, but it's not required. Many anglers catch walleye and pike from the bank during spring and fall.

What size fish should I expect to catch?

Walleye typically range from 12 to 18 inches, with occasional fish to 22 inches. Northern pike are often 18 to 28 inches, with larger fish possible. The pool holds a healthy population of both species, so consistent action is more likely than trophy-sized fish, though both are caught regularly.
