Constructed in 1937 by the USDA Forest Service, this Earth-type dam stands at a height of 40 feet and spans 280 feet in length. With a high hazard potential due to its uncontrolled spillway and maximum discharge capacity of 332 cubic feet per second, the lake offers a unique opportunity for water resource and climate enthusiasts to observe the intersection of man-made infrastructure and natural ecosystems.
The reservoir has a normal storage capacity of 454 acre-feet, with a total storage capacity of 517 acre-feet. Despite its small drainage area of only 1 square mile, Iron Creek Lake plays a crucial role in providing water for local wildlife and recreational activities. The dam's condition is currently not rated, but its risk assessment is moderate (3), highlighting the importance of ongoing monitoring and maintenance to ensure the safety and sustainability of this vital water resource. The surrounding area, with its picturesque scenery and diverse aquatic habitats, offers a prime location for studying the impacts of climate change on freshwater ecosystems and the resilience of man-made structures in the face of environmental challenges.
