Clair, Illinois, stands as a private structure nestled within the Village of Swansea. Constructed in 2003 by THOUVENOT, WADE & MOERCHEN, INC., this earth dam serves primarily for recreational purposes, offering a serene escape for water resource and climate enthusiasts. With a height of 13.5 feet and a length of 360 feet, the dam boasts a storage capacity of 34 acre-feet and a surface area of 2.86 acres, surrounded by a drainage area of 0.15 square miles.
Managed by the Illinois Department of Natural Resources (IDNR), Ravenel Lake Dam exhibits a high hazard potential despite its moderate risk assessment. The dam features an uncontrolled spillway with a width of 88 feet, allowing for a maximum discharge of 533 cubic feet per second. While the condition assessment is currently unavailable, routine inspections are conducted with a frequency of one year to ensure the structural integrity and safety of the dam. Although emergency action plans and inundation maps are not readily available, the dam remains a vital component of the local landscape, offering a haven for outdoor recreation and conservation efforts within the community.
