This is Mike Fish, broker and owner of Minnesota Real Estate & Management, and today we’re doing a complete lake profile on Platte Lake and Sullivan Lake. We’ve been doing these lake analyses one-on-one and privately for years, and it was recently suggested that I start putting them on the website as a resource. I think it’s a great idea—buyers consistently ask the same questions, and these two lakes deserve a proper overview.

I happen to live right next to Platte Lake. My boys and I fish it regularly, we ice-fish it every winter, and I will tell you honestly: when I moved here several years ago, I was amazed at how much of a hidden gem Platte and Sullivan really are. In terms of home prices and general popularity, they usually land around number 13 and 14 out of the regional lake rankings—still well below the “big-name” lakes, but absolutely packed with value and charm.

Because the lakes are connected, almost 2,700 total acres combined, and share many of the same buyer considerations, it makes sense to present them together.

What We Cover in a Lake Profile

When we create these lake evaluations, we try to answer the key questions buyers have before they drive 90 minutes up Highway 169 from the Twin Cities to see a property. Here are the common areas people want to understand:

• Lake size and depth

• Water quality and clarity

• Recreational use (boating, fishing, tubing, paddling, etc.)

• Shoreline types and overall “feel” of the lake

• Whether the lake is quiet or busy

• Local restrictions or lake-use rules

• Fishing quality and species present

• Public access points

• Local amenities—restaurants, services, and attractions

• Real estate values and recent sales history

Platte and Sullivan check nearly every box that lake-home buyers ask about.

Big Picture: Location & Accessibility

Both lakes sit just off Highway 169, making it a simple 90-minute drive from the metro. For many buyers, this convenience alone puts Platte and Sullivan on their shortlist. Brainerd is just a short drive away, meaning groceries, restaurants, bait shops, hardware stores, and medical services are all within quick reach.

Platte Lake: A Spacious, Quiet Recreational Lake

Size: ~1,750 acres
Max Depth: ~23 feet
Character: Quiet, spacious, family-friendly
Public Access: DNR landing available

Platte Lake is a great multi-use recreational lake and often surprises buyers with how large it feels once you’re out on the water. Although it’s on the shallow side, it offers:

• Northern pike

• Largemouth bass

• Walleye

• Crappie

• Sunnies and bluegill

Platte does have areas with vegetation—fairly normal for a shallower natural lake—but there is a very active lake association that works hard to control curly-leaf pondweed and keep the lake in good condition.

Boating & Bridge Access

Platte connects to Sullivan under a very wide and high bridge. I cannot imagine many boats that wouldn’t fit under it, though buyers should still double-check based on boat height. It’s a smooth, scenic channel, and there’s almost always someone fishing from the bridge—often my kids.

Real Estate on Platte Lake

Over the last few years:

• Lakeshore lots typically run $75,000 to $175,000+

• Cabins and lake homes generally sell around $400,000–$410,000+

• I’ve personally sold nine properties on Platte within the last three years

Platte remains quieter than many similar-sized lakes and is a fantastic option for buyers wanting value, elbow room on the water, and a relaxed lake environment.

Sullivan Lake: Deep, Scenic, and Strong Fishing

Size: ~1,200 acres
Max Depth: ~57 feet
Character: Moderate activity, stronger fishing reputation
Public Access: DNR access available

Sullivan Lake is just slightly smaller than Platte but significantly deeper—over twice the maximum depth—which contributes to clearer water and strong overall lake health.

Fishing on Sullivan

Sullivan is widely viewed as the better fishing lake between the two, particularly for:

• Walleye

• Crappie

• Bluegill

• Northern pike

• Bass

• And plentiful panfish

It’s a well-rounded fishery with consistent year-round action.

Real Estate on Sullivan Lake

Prices trend slightly higher than Platte:

• Lakeshore lots are often closer to $200,000

• Lake homes typically range $450,000–$500,000+

• Eleven properties have sold on Sullivan in the last three years

Sullivan feels a little more active on a nice summer day but still maintains a very comfortable, family-oriented lake culture.

Platte vs. Sullivan: How They Compare

Together, they function almost like a single two-lake system offering nearly 2,700 acres of water to explore.

Final Thoughts: Why Buyers Should Consider These Lakes

Platte and Sullivan consistently rank in the top tier of value lakes in the Brainerd Lakes Area. As buyers are pushed off the larger, more expensive lakes, these two continue to rise in desirability. They offer:

• Great recreation

• Very good fishing

• Convenient access from the metro

• A peaceful Northwoods feel

• Strong long-term value

• Reasonable price ranges

• Good potential for both personal use and STR income

I also have a detailed video covering the Top 20 Lakes in Central Minnesota, where Platte and Sullivan land right around spots 14 and 15.
