The Moundwood Boat Ramp is adjacent to the mouth of the South Fork of the Little Miami River where it enters Indian Lake.

The region of Indian Lake was originally a cluster of natural lakes situated on the Miami River. As the continental glaciers left Ohio, chunks of ice broke free, melted, and formed water-filled depressions called kettle lakes. The resultant shallow, marshy, natural lakes in this region covered an area of 640 acres. Among these were Old Indian Lake, Otter Lake, Blake Lake, Sheep Pen Lake, and the Buck Wheat Patch.

The present, and much larger, lake lies along one of the country’s major avian migration routes. Indian Lake is an important resting stop for birds such as Canada geese, ducks, grebes, swans, egrets, and herons. Many stay over the summer to nest.
