The Upper Salt Creek Structure 2 Dam, also known as Plum Grove Reservoir, is a vital piece of infrastructure located in Palatine, Cook County, Illinois. Constructed in 1984 by the Natural Resources Conservation Service, this earth dam stands at a height of 23 feet and spans a length of 2400 feet. With a primary purpose of flood risk reduction, the dam has a maximum storage capacity of 985 acre-feet and serves to protect the surrounding area from potential inundation during periods of heavy rainfall.

Managed by the local government, the Upper Salt Creek Structure 2 Dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and safety. The dam's spillway, with a width of 214 feet, helps to control overflow during high flow events, with a maximum discharge capacity of 9582 cubic feet per second. Despite its high hazard potential, the dam is rated as having a moderate risk level (3) and currently lacks detailed risk management measures. Enthusiasts of water resources and climate resilience can appreciate the crucial role that this dam plays in protecting the community and managing flood risks in the region.

As a significant piece of infrastructure in the region, the Upper Salt Creek Structure 2 Dam serves as a key component in the overall flood risk reduction strategy for Palatine and its surrounding areas. With its earth dam construction and buttress core design, the dam has been designed to withstand the hydraulic pressures of the tributary Salt Creek. The dam's normal storage capacity of 40 acre-feet helps to regulate water levels and reduce the potential for downstream flooding, showcasing the importance of sustainable water management practices in mitigating climate-related risks. Climate enthusiasts and water resource professionals can find inspiration in the collaborative efforts between local government agencies and the Natural Resources Conservation Service in ensuring the safety and resilience of this essential infrastructure.
