About Lake Mahopac
Lake Mahopac covers 587 acres in the town of Carmel, Putnam County, New York, about an hour north of New York City. The New York and Harlem Railroad turned it into a summer resort in the mid-1800s, with hotels running horse-drawn coach races to meet the trains; the hotels are gone, but the year-round lake community they left behind remains. Three private islands sit in the lake, including Petre Island's Massaro House, built in the style of Frank Lloyd Wright. The lake still holds a fishing record — a world-record brown bullhead came out of it in 2009 — and two marinas keep it busy with boats all summer.

Lake Mahopac depth chart, in wood
This is a Lake Mahopac depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 9 ft, 17 ft, 26 ft, 34 ft, 43 ft and deeper, down to the deepest hole at about 51 ft. The lake covers about 0.9 square miles, and 94 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 Mahopac 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 Mahopac 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 Mahopac.
Lake Mahopac 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 Mahopac; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Lake Mahopac 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.
