About Big Marine Lake
Big Marine Lake sits in Washington County, Minnesota, northeast of St. Paul. Like most lakes in the region, its basin was shaped by retreating glacial ice at the end of the last ice age, part of the moraine and kettle-lake landscape that spans the St. Croix River valley. The lake borders May Township and lies near Scandia, an area first settled by Swedish immigrant farmers in the mid-1800s before the shoreline filled in with lake homes and cabins for people commuting to the Twin Cities.
The lake covers about 1,596 acres with roughly 13 miles of shoreline, but its maximum depth is only around 57 feet, shallow relative to its surface area. Washington County runs Big Marine Park Reserve along the northeast shore, with a swimming beach, boat launch, and campground. The lake supports a fishery of walleye, muskellunge, and panfish that draws anglers from across the metro. Its shore is a mix of year-round houses and seasonal cabins, with boating and fishing as the main draw rather than dense development.

Big Marine Lake depth chart, in wood
This is a Big Marine Lake depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 10 ft, 19 ft, 29 ft, 38 ft, 48 ft and deeper, down to the deepest hole at about 57 ft. The lake covers about 2.6 square miles. The shape of the bottom is the real one from published soundings, so anglers recognise their drop-offs and points.
A Big Marine Lake map for the wall — or a gift
Most of these go to a cabin wall, a lake house entry, or a home office; a lot are gifts — the family that has been on Big Marine Lake for three generations, the retirement move, the first boat. The 12-inch is the desk-and-shelf size; the 24- and 30-inch boards read across a room. Add a line under the title and star your place on the shore, and it becomes the map of your Big Marine Lake.
Big Marine Lake map — the details
How big is the map?
Four sizes: 12, 17, 24 and 30 inches on the long side, from $149. Every size is cut from the same depth data of Big Marine Lake; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Big Marine Lake is cut layer by layer from published bathymetric soundings — each layer of birch is a depth contour, so the shape of the bottom is the real one, not decorative.
Can I add my own place on it?
Yes. At checkout you can add a line under the title (a family name, a cabin name, a year) and star the spot on the shore that matters to you.
How long does it take?
Made to order in Waterford, Pennsylvania and shipped in 7–10 days; shipping is free in the lower 48.
Can you make a lake that isn't listed?
Any lake in the United States — we hold depth data for 104,419 of them. Search for yours; if it isn't built yet we build it when you order.
