About Big Heart Lake
Big Heart Lake sits in the Cascade foothills of King County, Washington, within reach of Seattle but well removed from the city's grid. At roughly 126 acres with about three miles of shoreline, it is small enough to see across in one look yet large enough to hold a full circuit of homes and access points around its edge. The surrounding terrain is typical of the western Cascades foothill country: forested slopes, modest elevation gain, and a landscape shaped over time by the same glacial and volcanic forces that carved the broader Puget Sound lowland.
The lake's modest depth, a maximum of about 36 feet by modeled estimate, keeps it warmer through the summer than the larger, deeper lakes closer to the mountains, which makes it a draw for swimming and small-boat fishing rather than deep-water sport. Its position within easy driving distance of Seattle has made it attractive to people looking for a quieter, lower-key alternative to the region's more heavily developed lakefronts. The mix on the water tends toward local property owners and day visitors rather than large-scale recreation, keeping traffic and development around the shoreline comparatively light.

Big Heart Lake depth chart, in wood
This is a Big Heart Lake depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 6 ft, 12 ft, 18 ft, 24 ft, 30 ft and deeper, down to the deepest hole at about 36 ft. The lake covers about 0.2 square miles. The shape of the bottom is the real one from published soundings, so anglers recognise their drop-offs and points.
A Big Heart 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 Heart 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 Heart Lake.
Big Heart 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 Heart Lake; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Big Heart 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.
