This privately owned earth dam stands at a height of 34 feet and spans 550 feet in length, with a storage capacity of 83 acre-feet. The dam's normal storage level is 60 acre-feet, providing a surface area of 5 acres for recreational activities.
The dam, situated on the TR-GRASSY CREEK tributary, is regulated by the Illinois Department of Natural Resources and undergoes regular state inspections and enforcement measures. Despite being classified as having a low hazard potential, the risk assessment for Rockman Pond Dam 1 indicates a moderate level of risk. The spillway, with a width of 30 feet, is uncontrolled, and the outlet gates are also uncontrolled. The dam has not been modified in recent years, and its current condition assessment is not available.
While Rockman Pond Dam 1 serves as a valuable resource for fish and wildlife habitat as well as recreational opportunities, its risk level highlights the importance of ongoing monitoring and maintenance to ensure the safety and integrity of the structure. As climate change continues to impact water resources and infrastructure, the management of dams like Rockman Pond Dam 1 will be crucial in adapting to changing conditions and mitigating potential risks to surrounding communities and ecosystems.
