This private dam stands at a height of 25 feet and has a length of 250 feet, providing a maximum storage capacity of 22 acre-feet. Classified as an earth dam with stone core and soil foundation, it features an uncontrolled spillway with a width of 10 feet.
Despite its low hazard potential, Meyer's Dam 1 is subject to state regulations, inspections, and enforcement by the Illinois Department of Natural Resources. The dam's purpose extends beyond debris control to include other functions, with a normal storage capacity of 15 acre-feet and a maximum discharge rate of 12 cubic feet per second. While its risk assessment indicates a moderate risk level, the condition assessment is currently unavailable, and there is no Emergency Action Plan (EAP) in place.
In the event of any potential risks associated with Meyer's Dam 1, it is essential for stakeholders and authorities to prioritize the development of a comprehensive EAP, conduct regular inspections, and implement effective risk management measures to ensure the safety and integrity of this critical water resource infrastructure in Rock Island County, Illinois.
