About Canopus Lake
Canopus Lake sits inside Clarence Fahnestock Memorial State Park in the Hudson Highlands of Putnam County, New York. The park was created in 1929, when financier Alfred B. Fahnestock donated roughly 2,400 acres to the state in memory of his brother, Dr. Ernest Fahnestock, a physician who died while serving in World War I. The lake covers about 109 acres, with a shoreline near three miles and a maximum depth of roughly 32 feet. The Appalachian Trail crosses the park on its route north through the region.
The lake draws hikers, campers, and anglers from New York City and the Hudson Valley, many arriving by train to nearby Cold Spring before driving into the park. New York State stocks Canopus Lake with trout, and a swimming beach and boat launch sit near the campground on its northern shore. The surrounding hills carry traces of the region's 18th- and 19th-century iron mining industry, with old mine pits still visible along area trails. Winters bring cross-country skiers to the same trails that anglers and paddlers use the rest of the year.

Canopus Lake depth chart, in wood
This is a Canopus Lake depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 5 ft, 11 ft, 16 ft, 21 ft, 27 ft and deeper, down to the deepest hole at about 32 ft. The lake covers about 0.2 square miles, and 5 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 Canopus 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 Canopus 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 Canopus Lake.
Canopus 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 Canopus Lake; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Canopus 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.
