What Enemy Swim Lake offers anglers
Enemy Swim Lake is a shallow, weedy prairie lake in Roberts County, South Dakota, about 15 miles northeast of Waubay. It runs roughly 3 miles long and 1.5 miles wide, with an average depth around 8 feet and a maximum depth near 20 feet. The lake sits in glacial terrain dotted with cattail marshes, bulrushes, and scattered emergent vegetation—the kind of structure that holds walleye and northern pike year-round.
The fishery is strongest for walleye and northern pike, with some panfish mixed in. Walleye here respond well to live bait presentations and jigging along the deeper edges where weed lines meet open water. Pike are aggressive and abundant, especially in spring and fall when they move into the shallows to hunt. The lake's shallow profile and heavy weed growth make it a different animal than the deeper Waubay lakes nearby—you're working structure constantly rather than suspending over deep basins.
Key Takeaways
- Enemy Swim is a shallow prairie lake best known for walleye and northern pike, with average depths around 8 feet and heavy weed cover throughout.
- Spring and fall produce the most consistent walleye action, particularly around weed edges and the few deeper holes the lake holds.
- Pike fishing is strong year-round, with the best results in shallow water during low-light periods and around emergent vegetation.
- Public access is available at a South Dakota Game, Fish and Parks boat ramp on the north shore; the lake is open to year-round fishing including winter.
Walleye patterns through the seasons
Spring walleye on Enemy Swim begin moving shallow as water temperatures climb into the 40s and 50s. Focus on the transition zones where deeper water meets the weed line—typically 6 to 10 feet. Live shiners or fathead minnows under a slip bobber work well during the pre-spawn period. As the season progresses into May and June, walleye scatter into the weeds themselves, and jigging with live bait becomes more effective than bobber fishing.
Summer is the toughest season. Walleye retreat to the deepest holes and the thickest weed cover. Early morning and late evening jigging in 12 to 18 feet of water, or working the densest weed edges with soft plastics, will produce fish, but the bite is slower and more selective than spring. Many anglers shift focus to pike during midsummer or fish the low-light hours.
Fall is when Enemy Swim shines again. As water cools in September and October, walleye move back to the weed edges and shallower structure. Live bait presentations and crankbaits that mimic the baitfish in the lake produce steady action. Winter jigging through the ice also works well—the same deep holes and weed edges that hold fish in summer hold them under the ice.
Northern pike and shallow-water hunting
Pike on Enemy Swim are not subtle. They hunt the shallow weeds and the edges where cattails meet open water. Spring pike fishing begins as soon as the ice clears and water temperatures reach the mid-40s. Throw large swimbaits, spinnerbaits, or topwater lures along the weed line and in the shallow bays. Early morning and overcast days produce the best results.
Summer pike fishing slows during the heat of the day but picks up again in evening and early morning. Focus on the deepest weed edges and any open-water channels that cut through the vegetation. Fall pike fishing rivals spring for consistency—cooler water pushes pike into aggressive feeding mode, and they're less selective about lure choice.
Winter pike fishing through the ice can be productive if you find the right holes. Pike don't move far in winter, so locating them requires some exploration. Once you find a concentration, the bite can be steady. Live baitfish under a tip-up or jigging with large spoons and swimbaits both work.
Access and boat ramp details
Public access to Enemy Swim Lake is available at a South Dakota Game, Fish and Parks boat ramp on the north shore. The ramp is maintained year-round and accommodates both trailer boats and hand-launch canoes or kayaks. Parking is available at the ramp, and the facility is open during daylight hours. There is no fee to launch.
The ramp can get crowded during peak weekends in spring and fall, particularly on Saturdays. If you're planning a trip during those times, arriving early in the morning improves your chances of finding a parking spot. Winter access is available for ice fishing, though you'll need to check current ice conditions with South Dakota Game, Fish and Parks before heading out.
Regulations and what you need to know
South Dakota requires a fishing license for anyone 16 and older. A South Dakota fishing license can be purchased online through the Game, Fish and Parks website, at sporting goods retailers, or at the boat ramp itself. Licenses are available as daily, 3-day, or annual options. Non-residents pay a higher rate than residents.
Enemy Swim Lake follows standard South Dakota walleye and pike regulations. Walleye have a daily bag limit and a minimum size requirement; pike have their own bag and size limits. Regulations can change year to year, so check the current South Dakota fishing guide before you fish. The guide is available on the Game, Fish and Parks website and lists all species-specific rules for the state.
The lake is open year-round, including winter ice fishing. If you plan to fish in winter, bring a portable shelter, a hand auger or power auger, and appropriate safety gear. Ice thickness varies depending on how cold the winter has been—never assume ice is safe without checking current conditions with local bait shops or the Game, Fish and Parks office.
Nearby lakes and the Waubay chain
Enemy Swim sits within reach of several other productive lakes in the Waubay National Wildlife Refuge area. Waubay Lake itself, about 10 miles south, is larger and deeper, with a different character and fish populations. Days Lake and Pickerel Lake are also nearby and worth exploring if you want variety or if one lake isn't producing on a given day.
The Waubay area is known for its prairie lake fishery, and the lakes here are connected by history and geography even if they're not directly connected by water. Each has its own personality—Enemy Swim's shallow, weedy profile makes it distinct from the deeper basins nearby. If you're planning a multi-day trip to the region, fishing several lakes gives you a fuller picture of what the area offers.
Frequently Asked Questions
What's the best time of year to fish Enemy Swim Lake?
Spring (April through May) and fall (September through October) are the most consistent seasons for both walleye and pike. Summer fishing is possible but slower, and winter ice fishing can be productive if you're willing to deal with cold weather and uncertain ice conditions.
Can I fish Enemy Swim Lake in winter?
Yes, the lake is open year-round for ice fishing. Check current ice thickness and conditions with local bait shops or South Dakota Game, Fish and Parks before heading out. Never assume ice is safe without verifying conditions first.
Do I need a boat to fish Enemy Swim Lake?
A boat gives you access to more water and deeper structure, but the lake can be fished from shore in some areas, particularly around the boat ramp and along the north shore. A canoe or kayak is also an option for anglers who want to explore the shallows and weed edges.
What size pike and walleye can I expect to catch?
Walleye typically range from 12 to 18 inches, with some larger fish present. Pike are often in the 18 to 28-inch range, with occasional fish pushing 30 inches or more. The lake produces solid numbers of both species rather than trophy-sized fish, though larger individuals are always possible.
Is there a bait shop near Enemy Swim Lake?
The closest services are in Waubay, about 15 miles south. Bring your own bait or plan to stop in town before heading to the lake. Having bait on hand before you arrive saves time and ensures you have what you need for the conditions you find.
