Built in 1933 by Caldwell Engineering Co., this earth dam stands at a height of 42 feet and stretches 275 feet in length, creating a reservoir with a storage capacity of 325 acre-feet. The dam, situated on the Trib Jobs Creek, serves for water supply in addition to recreational activities, covering a surface area of 23 acres and draining a 0.9 square mile watershed.
Managed by the Illinois Department of Natural Resources (IDNR), Virginia Lake Dam is state-regulated and undergoes regular inspections, with a high hazard potential due to its significant risk level. The dam features an uncontrolled spillway with a width of 46 feet and an outlet gate system. Despite its moderate risk assessment, the condition assessment of the dam is currently not available, signaling a need for further evaluation and potential risk management measures. As a popular spot for outdoor enthusiasts, Virginia Lake Dam plays a vital role in providing water resources and recreational opportunities in the region.
