Upper Salt Creek Structure 4 Dam, also known as Twin Lakes Reservoir, is a vital infrastructure in Cook County, Illinois, designed to mitigate flood risks along the Salt Creek. Completed in 1987 by TORNROSE, CAMPBELLANDASSOC., this earth dam stands at a height of 14 feet and spans 3000 feet, providing a storage capacity of 775 acre-feet. The dam serves a primary purpose of flood risk reduction and also supports recreational activities in the area.
Managed by the local government and regulated by the Illinois Department of Natural Resources, Upper Salt Creek Structure 4 Dam poses a high hazard potential but is currently assessed as moderate risk. Despite its critical role in protecting the surrounding community from flooding events, the dam's condition assessment is not available, highlighting the importance of regular inspections and maintenance to ensure its structural integrity. With a spillway width of 32 feet and a maximum discharge capacity of 1300 cubic feet per second, the dam is well-equipped to handle significant water flow during peak periods.
Located in Palatine, Illinois, Upper Salt Creek Structure 4 Dam is a key component of the region's water resource management infrastructure. As climate change continues to impact precipitation patterns and extreme weather events, the dam plays a crucial role in safeguarding communities and ecosystems along the Salt Creek watershed. Its strategic design and operational oversight by the Natural Resources Conservation Service demonstrate a commitment to resilience and preparedness in the face of evolving environmental challenges.
