About The River

Nestled in the heart of South Dakota’s plains, Split Rock Creek – a tributary of the Big Sioux River, is a nature lover’s delight. Deriving its name from the intriguing Split Rock formation along its banks, the creek offers an inviting charm in every season.

Split Rock Creek was historically appreciated by the Corson settlers, who arrived in the late 19th century. Fascinatingly, this river was a source of both, sustenance and recreational fishing for them.

  • 1893: The first settlers discover the tranquil beauty of the creek.
  • 1934: The WPA erects the charming stone buildings and picnic shelters that still stand today.
  • 1955: Split Rock Creek State Park is established.

Today, the creek is a beloved spot for kayaking, camping, fishing, and picnics. As you stroll down its banks, it’s a delight to imagine the footsteps of the pioneers before.
