Located in Corydon, Iowa, the Corydon Reservoir Dam stands as a testament to engineering excellence, completed in 1974 by THOMPSON, WILLIS & CO. and the USDA NRCS. This earth dam spans 750 feet in length and reaches a height of 26 feet, creating a reservoir with a maximum storage capacity of 870 acre-feet. The primary purpose of this dam is for recreation, offering a surface area of 66.9 acres for water enthusiasts to enjoy.
Regulated by the Iowa DNR, the Corydon Reservoir Dam is inspected every five years, with the latest assessment in May 2018 deeming its condition as satisfactory. Despite its significant hazard potential, the risk assessment classifies the dam as moderate. With a spillway width of 47 feet and uncontrolled spillway type, the dam ensures proper water management for the TR-WEST JACKSON CREEK. As water resource and climate enthusiasts, the Corydon Reservoir Dam serves as a reminder of the vital role dams play in both recreation and flood control efforts in the state of Iowa.
