Sterling, Iowa, is a privately owned structure designed by the USDA NRCS for the primary purpose of grade stabilization along the Tr-Fox River. Completed in 2000, this earth dam stands at a height of 25 feet and stretches for 470 feet, offering a storage capacity of 82 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam serves to regulate water flow and prevent erosion in the surrounding area.
Managed by the Iowa Department of Natural Resources, Gilchrist Dam is subject to state regulation, permitting, inspection, and enforcement to ensure its structural integrity and safety standards are upheld. Despite not having a current condition assessment, the dam is classified as not rated and does not have an Emergency Action Plan (EAP) in place. The spillway type is uncontrolled with a width of 2 feet, and the dam has a surface area of 4 acres, serving a drainage area of 0.36 square miles.
Water resource and climate enthusiasts may find Gilchrist Dam a fascinating structure to study due to its role in grade stabilization and water flow regulation along the Tr-Fox River. With its modest height and storage capacity, the dam presents an opportunity to explore how earth dams contribute to environmental conservation efforts in Iowa. As a privately owned and state-regulated facility, Gilchrist Dam exemplifies the collaborative efforts between government agencies and private entities to manage water resources effectively and sustainably.
