About Lake Grosvenor
Lake Grosvenor sits inside Katmai National Park in southwest Alaska, feeding into Lake Coville and then Naknek Lake through a short connecting river. Robert Griggs named it during the National Geographic Society's survey expeditions of the 1910s, which mapped the region after the 1912 Novarupta eruption buried the nearby Valley of Ten Thousand Smokes in ash. The name honored Gilbert Grosvenor, the Society's longtime president, who funded the surveys but never traveled to the lake himself.
Access is by floatplane out of King Salmon, the small town that serves as the gateway to Katmai's interior lakes. There are no roads in. The lake and its outlet stream are known among anglers for rainbow trout that follow sockeye salmon runs upstream from Naknek Lake, and guided fishing camps have operated on its shore for decades. Traffic is limited to pilots, guides, park staff, and clients flying in for a few days at a time, not year-round residents.

Lake Grosvenor depth chart, in wood
This is a Lake Grosvenor depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 40 ft, 80 ft, 119 ft, 159 ft, 199 ft and deeper, down to the deepest hole at about 239 ft. The lake covers about 42.4 square miles. The shape of the bottom is the real one from published soundings, so anglers recognise their drop-offs and points.
A Lake Grosvenor 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 Grosvenor 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 Grosvenor.
Lake Grosvenor 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 Grosvenor; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. Lake Grosvenor 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.
