About South Tenmile Lake
South Tenmile Lake sits behind a wall of coastal sand dunes in Coos County, Oregon, one part of the connected Tenmile Lakes system that drains west to the Pacific near Coos Bay. The dunes sealed off an old river valley, backing up fresh water into a lake with a footprint of roughly 937 acres and a shoreline that runs close to 19 miles. Soundings have found depths near 321 feet in places, unusual for a lake held in by sand rather than rock or a dam.
The town of Lakeside sits on the lake's shore and serves as the main access point, with public boat ramps and a marina used by anglers year-round. South Tenmile is known chiefly for its largemouth bass, warm and weedy compared to most Oregon coastal water, and hosts bass tournaments through the season. Cabins and vacation homes line stretches of the shore, and the connected North Tenmile Lake and nearby Eel Lake make the area a hub for coastal freshwater boating.

South Tenmile Lake depth chart, in wood
This is a South Tenmile Lake depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 54 ft, 107 ft, 161 ft, 214 ft, 268 ft and deeper, down to the deepest hole at about 321 ft. The lake covers about 1.6 square miles. The shape of the bottom is the real one from published soundings, so anglers recognise their drop-offs and points.
A South Tenmile 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 South Tenmile 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 South Tenmile Lake.
South Tenmile 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 South Tenmile Lake; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. South Tenmile 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.
