Lake Carlton Dam, located in Whiteside County, Illinois, is a state-regulated structure built in 1969 with the primary purpose of recreation. The dam, standing at a height of 41 feet and stretching 1030 feet in length, creates Lake Carlton by impounding water from the Trib Rock Creek. With a storage capacity of 1742 acre-feet and a surface area of 77 acres, the dam serves as a popular recreational spot for residents and visitors in the city of Morrison.

Managed by the Illinois Department of Natural Resources (IDNR), Lake Carlton Dam poses a high hazard potential due to its uncontrolled spillway and outlet gates. Despite its age, the dam has undergone regular inspections, with the last one conducted in August 2020. While the condition assessment is currently unavailable, the risk assessment categorizes Lake Carlton Dam as having a moderate risk level, prompting the need for ongoing risk management measures to ensure the safety and integrity of the structure.

For water resource and climate enthusiasts, Lake Carlton Dam offers a fascinating look into the intersection of human infrastructure and natural ecosystems. As a key feature in the local landscape, the dam provides not only recreational opportunities but also important water storage and flood control functions. Its design by CASLER & ASSOCIATES and ongoing management by state authorities highlight the collaborative efforts involved in maintaining water resources in a changing climate.
