🏞️About Lake Carlos

Lake Carlos is a 2,605-acre, 163-foot-deep basin about four miles north of Alexandria — the largest and deepest lake in the Alexandria Chain, with water clarity that now regularly exceeds 20 feet in summer since zebra mussels arrived. It's best known as a bass and panfish lake, with a DNR-supplemented walleye fishery and one of the only burbot populations in the region.

Why Fish Lake Carlos?

  • 163 feet deep — the deepest basin in the Alexandria Chain, with water clarity regularly exceeding 20 feet in summer
  • A genuine bass-tournament lake: largemouth over 19" and smallmouth over 20" were sampled in the 2024 survey
  • One of the few lakes in the Glenwood Management Area known to hold burbot
  • Four public accesses, including one inside Lake Carlos State Park with a fish-cleaning station and swim beach

💡Local Tips for Lake Carlos

  • 1Northern pike run small here ("hammer handles" are common) — harvesting small pike is encouraged, and the lake sits in the North-Central protected-slot zone (22–26" must be released, no more than 2 over 26" of your 10-pike limit)
  • 2Walleye is a supplemented fishery, not a self-sustaining one — DNR fingerling/yearling stocking happens most years, plus additional private stocking permitted through the Lake Carlos Association
  • 3Designated a Sentinel Lakes "Tier One" site — one of Minnesota's most closely long-term-monitored lakes

🚤Access Points

  • West access

    Deep-water dock with ample parking — suited for larger boats

  • North access (Lake Carlos State Park)

    Concrete ramp and dock inside the state park — requires a Minnesota State Parks permit; fish-cleaning station and swim beach on site

  • Northeast & east accesses

    Smaller launches with limited parking

  • Rotary Beach (Lake Le Homme Dieu)

    On the connected lake near the channel into Carlos — frequently used as an alternate launch

🗺️Where to Fish

  • Alexandria Chain channels (Le Homme Dieu / Darling)

    Navigable connections to the rest of the chain — current seams near the channel mouths hold fish

  • Outlet toward the Long Prairie River

    Modified to a rock-arch rapids in 2021 — a popular float/paddle start, with current-break structure right at the outlet

  • Main-basin drop to 163 feet

    One of the deepest basins in the chain — a genuine deep-water refuge in summer, especially for tullibee

📅Seasonal Fishing Patterns

🌸 Spring

Bass move onto shallow rock and sand near the state park and channel mouths to spawn.

☀️ Summer

Exceptional water clarity pushes fish deeper during the day — main-basin drop-offs and channel current seams produce best.

🍂 Fall

Bass and panfish stack near the channels connecting to Darling and Le Homme Dieu.

❄️ Winter

A quieter ice lake relative to its open-water tournament traffic — panfish over structure near the accesses.

🐠Other Species

Largemouth Bass

Abundant and tournament-grade — fish over 19" were sampled in the 2024 survey.

Smallmouth Bass

Abundant and tournament-grade — fish over 20" were sampled in the 2024 survey.

Burbot

One of the only lakes in the Glenwood Management Area known to hold burbot, though not reliably caught by standard survey gear.

Tullibee (Cisco)

Abundant in the deep main basin but not reliably sampled by standard survey gear — an important cold-water forage species.

Walleye here is a supplemented fishery, not a self-sustaining one — DNR fingerling/yearling stocking happens most years, plus additional private stocking permitted through the Lake Carlos Association. Burbot have also been documented, one of the only lakes in the Glenwood Management Area known to hold them.

Frequently Asked Questions

How deep is Lake Carlos?+

Lake Carlos reaches 163 feet at its deepest point and averages about 50 feet, across 2,605 acres — the deepest basin in the Alexandria Chain of Lakes.

Is Lake Carlos good for bass fishing?+

Yes — Lake Carlos is a genuine bass-tournament lake. The 2024 DNR survey sampled largemouth bass over 19" and smallmouth bass over 20", and the Alexandria Chain hosts several bass tournaments each year.

Where do I access Lake Carlos?+

Four public accesses: west and north (better for larger boats — the north access is inside Lake Carlos State Park and requires a state parks permit), northeast and east (smaller, limited parking), plus Rotary Beach on the connected Lake Le Homme Dieu near the channel into Carlos.

Does Lake Carlos have walleye?+

Yes, but it's a supplemented rather than self-sustaining fishery — expect low-to-moderate numbers of harvestable-size fish. Average size in the 2024 survey was 16.0" and 1.7 lbs.

Do I need a fishing license to fish in Minnesota?+

Yes — anyone 16 or older needs a valid Minnesota fishing license to fish any lake in the state. A resident annual license runs about $25, non-resident around $51, with short-term options (24-hour, 72-hour, 7-day) also available online or at local bait shops. Anglers under 16 and residents 90+ are exempt. Prices can change year to year — verify current fees at the DNR before buying.

What's the best time of day to fish?+

Early morning (dawn through a few hours after sunrise) and evening (a few hours before dusk through dark) are generally the most productive windows, when gamefish like walleye and bass feed most actively in low light. Midday can still produce, especially on cloudy or windy days or by fishing deeper structure.

What's the best time of year to fish in Minnesota?+

Minnesota fishing is essentially year-round. The open-water season runs from the general fishing opener in mid-May through fall, with spring (post-spawn) and fall (pre-winter feeding) often producing the most active bites. Ice fishing typically runs December through February or March once lakes freeze safely.

Can I fish from shore, or do I need a boat?+

Both work on most Minnesota lakes. Shore and pier fishing near public accesses is a great option, especially for panfish, though a boat opens up more structure and deeper water where species like walleye often hold — particularly on larger lakes.

What basic gear do I need to get started?+

A medium-action spinning rod and reel, 6–10 lb test line, a small tackle box with jigs, hooks, and a few live-bait rigs, plus a Minnesota fishing license covers most beginner trips. Live bait (nightcrawlers, leeches, minnows) is effective and easy to find at bait shops near most popular lakes.

How do I find current fishing regulations for a specific lake?+

Check the Minnesota DNR's LakeFinder tool (dnr.state.mn.us/lakefind) by searching the lake name or DOW number — it shows any lake-specific regulations, like special slot limits, alongside statewide rules. Regulations can change year to year, so verify before you keep fish even on a lake you've fished before.

How thick does ice need to be for safe ice fishing?+

The DNR recommends at least 4 inches of new, clear ice to support a person on foot, and 5–7 inches for a snowmobile or ATV — considerably more for any vehicle. Ice thickness varies across a single lake and can be a foot thick in one spot and dangerously thin a few feet away. The DNR doesn't measure or guarantee ice safety on any lake, so check thickness yourself as you go.

What should I do if I catch a fish I'm not sure I should keep?+

When in doubt, release it. Check the DNR's current size and possession limits for the species and lake before fishing, and be aware some lakes and species carry fish consumption advisories from the MN Department of Health for mercury or other contaminants — a separate concern from possession regulations, and worth checking too.

Do I need a fishing guide?+

Not required, but worth considering for a first trip to a large or unfamiliar lake — local guides know current structure, depth, and patterns that can take years to learn on your own, especially on big water like Lake of the Woods or Mille Lacs. On smaller, well-mapped lakes, most anglers do fine self-guided.

Where can I find current fishing reports and conditions?+

Check this site's fishing forecast and weather pages for current conditions, or the DNR's LakeFinder for lake-specific water clarity, temperature, and survey data. Local bait shops near a given lake are also a reliable source for what's actually biting that week.

💡Quick Tips

  • Check ice conditions before winter fishing - never trust visual appearance alone
  • Early morning and late evening are typically best for walleye
  • Always have a valid Minnesota fishing license before fishing
  • Clean, drain, and dry boats to prevent invasive species spread
