The Amana Fish Weir is a rare example of Native American architecture in Iowa that looks much as it did when first constructed.  Fish weirs are structures of wood or stone that forced fish swimming downstream into a narrow corridor or a single point where waiting Native American hunters could spear, net, or hook them as they passed. The Amana Fish Weir is the best-documented example of such a structure in Iowa if not the entire Midwest. The Amana Fish Weir was first recorded in the 1844 and was most likely constructed or at least utilized by Meskwaki Indians living nearby in the early 1800s. Settlers, primarily those from the Amana Colonies, found the weir a rich fishing spot and the site became a local landmark before becoming a State preserve in in 1976 and placed on the National Register of Historic Places in 1988.

The weir, originally appearing as a 20-inch high dam, became progressively less visible through time. The construction of the Coralville Reservoir raised water levels at the site and the weir was only visible during periods of prolonged droughts. Concern over the present condition of the weir was raised when no one is known to have seen the structure since the late 1990s. A review of historic photographs and aerials by the OSA concluded the Iowa River channel had moved to the north and the weir was either buried or destroyed. In 2018, a survey funded by a State Historical Society of Iowa Historical Resource Development Program grant was conducted by the OSA used soil probes and a laser transit to create a 3-D model of the former riverbed at the suspected location of the weir, now a grassy field. The resulting map shows the weir is buried intact under about 8 feet of silt and sand. Although no longer visible, the weir is protected by burial and could reemerge someday if the river changes course again.
