Although the condition assessment is currently listed as 'Not Available,' the dam's emergency action plan status and risk management measures are also under review for future updates.
Water resource and climate enthusiasts will appreciate the unique features of Walnut Point Dam, such as its uncontrolled spillway system and the tranquil environment it provides for fish and wildlife. With its strategic location in Peoria County and the active involvement of private ownership, this dam serves as a valuable asset for both environmental conservation and recreational activities in the region. As efforts continue to maintain and improve the dam's infrastructure, it remains an important landmark for water management and conservation efforts in Illinois.
