About William H. Harsha Lake
Harsha Lake formed when the U.S. Army Corps of Engineers dammed the East Fork of the Little Miami River, completing the project in 1978 after decades of flooding in the region. The reservoir was named for William H. Harsha, a U.S. Representative from Ohio who pushed the flood-control project through Congress. It sits inside East Fork State Park in Clermont County, roughly 25 miles east of Cincinnati, near the towns of Bethel, Batavia, and Owensville.
The lake covers about 1,932 surface acres and draws bass anglers, sailors, and campers from the greater Cincinnati area. Horsepower restrictions keep boat traffic lighter than on larger regional reservoirs, and the surrounding state park adds camping, trails, and swim beaches along the shoreline. As one of the primary flood-control structures on the Little Miami watershed, the lake still functions to protect downstream towns along the river and, further on, the Ohio River.

William H. Harsha Lake depth chart, in wood
This is a William H. Harsha Lake depth chart you can hang: 6 stacked layers of birch, each one a depth contour — 9 ft, 19 ft, 28 ft, 37 ft, 47 ft and deeper, down to the deepest hole at about 56 ft. The lake covers about 3.2 square miles, and 73 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 William H. Harsha 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 William H. Harsha 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 William H. Harsha Lake.
William H. Harsha 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 William H. Harsha Lake; the bigger boards carry more shoreline roads and place names.
Is it made from real depth data?
Yes. William H. Harsha 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.
