What Palmer Lake offers anglers

Palmer Lake is a 1,200-acre impoundment that sits about eight miles south of Boulder Junction, Wisconsin, and it holds walleye, northern pike, and largemouth bass in water that reaches 80 feet deep in places. The lake was created by damming the Trout River, and that current—especially near the dam and in the narrows between the main basin and the upper arms—concentrates fish and creates the kind of structure that makes walleye and pike predictable. The deep basin itself is cold enough to hold walleye through summer, which means you can fish it year-round without the fish vanishing into the thermocline the way they do in shallower lakes.

Palmer is not a trophy lake in the sense that every cast produces a five-pound walleye. What it is, though, is a lake where you can catch walleye consistently across a long season, where pike run bigger than they do in many Northwoods lakes, and where the structure is obvious enough that a visiting angler can read the map and find fish without hiring a guide. The shoreline is mostly undeveloped—state land, national forest, and a few old cottages—which means the lake has not been pounded by pressure the way some closer-to-town water has.

Key Takeaways

  • Palmer Lake reaches 80 feet deep and stays cold enough for walleye through summer, making it fishable from ice-out through freeze-up.
  • The dam, the narrows, and the current-swept channel between the main basin and upper arms hold walleye and pike year-round.
  • Early spring and fall are peak seasons; summer walleye move to the deepest basins and respond to live bait and vertical jigging.
  • Pike fishing is strong in the shallower arms and around weed edges in spring and early summer.
  • A Wisconsin fishing license and a trout stamp are required; the lake is open to public access via the Boulder Junction public landing.

Spring walleye fishing — ice-out through May

Palmer Lake walleye move shallow in spring to spawn, and they linger in the shallows longer than they do in many lakes because the water stays cold. From ice-out through mid-May, fish the narrows between the main basin and the upper arms—this is where current pushes food and where walleye stack up before and after the spawn. Work jigs tipped with live minnows or crawlers in 8 to 15 feet of water, and do not overlook the shallow flats on either side of the narrows; walleye will be there too, especially on overcast days and in the first and last hours of light.

The dam area also produces in spring. Fish the deeper water immediately below the dam and along the face itself; walleye hold there to intercept food drifting through the current. A slip-sinker rig with a live minnow, worked slowly along the bottom, is a standard approach. By late May, as the water warms, walleye begin to move deeper, and you will need to follow them into the 30- to 50-foot range.

Summer walleye — June through August

Summer walleye on Palmer Lake are deep, but they are not scattered. The lake's depth means there is a true thermocline—a layer of water where temperature changes sharply—and walleye sit just above it, usually in the 40- to 65-foot range depending on the week. The main basin holds the most fish, and the deepest holes near the dam are worth checking, but do not ignore the deeper pockets in the upper arms; walleye use these as secondary holding areas.

Live bait is the most reliable summer approach. Drop a live minnow on a slip-sinker rig to the bottom, then work it up a few feet; walleye will come up to meet it. Vertical jigging with a live minnow or a soft plastic also works, especially if you are marking fish on your sounder. The bite is often better at night and in the first hour after sunrise; midday fishing is possible but slower. Water temperature in summer typically ranges from 72 to 76 degrees at the surface, so the deeper, cooler water is essential.

Fall walleye and pike — September through October

Fall is when Palmer Lake fishes best. Water temperature drops, walleye move shallower and more active, and pike begin to feed aggressively in preparation for winter. From early September through mid-October, fish the narrows and the shallower arms again—the same areas that produced in spring, but now with better weather and longer periods of active feeding. Jigs and live bait work, but so do crankbaits and spinners; walleye are less finicky in fall.

Pike fishing in fall is excellent around weed edges and in the transition zones between shallow and deep water. Throw large swimbaits, bucktail spinners, or topwater lures in the 6- to 15-foot range. The upper arms of the lake, which are shallower and warmer than the main basin, concentrate pike in fall and are worth focusing on if you want to target them specifically.

Winter fishing and ice conditions

Palmer Lake typically freezes solid by mid-December and stays frozen through March. Ice thickness varies by year, but the lake is generally safe for ice fishing by late December. The same deep basins that hold walleye in summer hold them under the ice, so drill holes over 40 to 60 feet of water and fish live minnows on a jigging rod. The narrows also produce in winter; the current keeps a small area open or thin, and walleye congregate there.

Pike can be caught through the ice, but they are less predictable than walleye. Focus on the shallower arms and around structure—fallen trees, rock piles, weed edges—in 15 to 30 feet of water. Winter on Palmer Lake is quieter than fall or spring, but the fishing is steady if you are willing to sit still and wait.

Access, regulations, and what to bring

Palmer Lake has a public boat landing on the north shore, accessible via Forest Road 383 south of Boulder Junction. The landing has parking for about 20 vehicles and a single-lane concrete ramp. There is no fuel or bait shop at the landing, so bring what you need from town. A Wisconsin fishing license and a trout stamp are required; the trout stamp is necessary because Palmer Lake is classified as a trout lake even though walleye and pike are the primary target. The lake is open year-round.

Bring a map and a sounder if you have one; Palmer's depth and structure reward knowing where you are. Live minnows and crawlers are the most reliable baits, and you can pick them up at tackle shops in Boulder Junction before heading out. The lake can get windy in afternoon, so plan to fish early and be off the water by midday if the forecast calls for wind.

Frequently Asked Questions

Do I need a boat to fish Palmer Lake?

A boat is the most practical way to reach the deeper structure and the narrows where walleye concentrate. Shore fishing is possible from the landing area and from state land around the lake, but you will be limited to shallower water and the immediate vicinity of the dam.

What size walleye and pike does Palmer Lake produce?

Walleye average 12 to 16 inches, with fish in the 18- to 22-inch range caught regularly. Pike average 18 to 24 inches, and fish over 30 inches are possible. The lake is not known for trophy-sized fish, but the consistency of the bite makes up for it.

Can I fish Palmer Lake in summer if I do not have a sounder?

Yes, but it is harder. Fish the known deep holes and the dam area, and use live bait on a slip-sinker rig; walleye will find the bait even if you cannot see them on a screen. A sounder makes summer fishing much more efficient, but it is not required.

Is there a size or bag limit on walleye and pike?

Wisconsin walleye regulations vary by lake and change annually; check the current Wisconsin Department of Natural Resources fishing guide before you go. Pike have a separate bag limit. Regulations are posted at the landing and online at the DNR website.

What is the best time of year to visit Palmer Lake?

Fall (September through mid-October) offers the most consistent fishing and the best weather. Spring (April through May) is also excellent and less crowded. Summer is possible but requires deeper fishing and more patience; winter is for dedicated ice anglers.
