The highways either side of Lake Oahe are named 1804 and 1806. These represent the years that Lewis and Clark traveled up and down the Missouri River. Development along the lake is limited to few areas and the majority of shoreline is wilderness. Many kinds of wildlife abound along the shores. Trophy deer, goose and phenomenal pheasant hunting are available along most of the lake.
Fishing is year round.
There are many ancient Native American villages and burial sites along the lake.
