With a low hazard potential and moderate risk assessment, Dam 18 is designed with a buttress core and is primarily used for flood control purposes. The dam features an uncontrolled spillway with a width of 32 feet, ensuring the safe release of excess water during times of high flow.
Despite not being regulated by the state, Dam 18 undergoes regular inspections with a frequency of 4 times a year to ensure its structural integrity and safety. The last inspection was conducted in September 2020, with a condition assessment currently marked as "Not Available". While the dam does not have an Emergency Action Plan (EAP) in place, it is equipped with emergency contacts and meets moderate risk management guidelines. With its vital role in flood control and water resource management in the region, Dam 18 continues to play a crucial role in safeguarding the surrounding communities from potential risks and hazards associated with extreme weather events.
