About Lake Washington
Lake Washington is the second-largest natural lake in the state, a twenty-two-mile ribbon between Seattle and the Eastside carved by the Puget lobe of the last ice sheet and filled to 214 feet at its deepest. Mercer Island sits in its southern half; the two floating bridges that cross it are among the longest of their kind in the world, and the lake is why Seattle commutes the way it does.
The shoreline runs from Laurelhurst and Madison Park through Medina, Hunts Point and Yarrow Point — some of the most expensive waterfront in America — down to Renton at the south end. In the 1960s the lake was famously rescued from decades of sewage with a regional cleanup that is still taught as the textbook case of a big lake brought back.

Lake Washington depth chart, in wood
This is a Lake Washington depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 36 ft, 71 ft, 107 ft, 143 ft, 178 ft and deeper, down to the deepest hole at about 214 ft. The lake covers about 33.1 square miles, and 19374 shore roads are engraved around it. The shape of the bottom is the real one from published soundings, so anglers recognise their drop-offs and points.
A Lake Washington 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 Lake Washington 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 Lake Washington.
Lake Washington 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 Lake Washington; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Lake Washington 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.
