Flooding of the Cottonwood River has pushed water into the lower level of the Drinkwater and Schriver Flour Mill at Cedar Point, Kansas. The mill, unused since the 1960s. is listed on the National Record of Historic Places and is owned by a nonprofit corporation that is raising money to fund restoration. Despite the prominent cracks in the walls, the mill is believed to be sound. It sits on bedrock and the lower-level walls are 42 inches thick. The mill was built as a sawmill in 1867 when a log dam was built across the river; its purpose soon after was turned to grain milling, and the dam was replaced with one of stone.
