Built in 1992, this earth dam stands at a height of 31 feet with a length of 280 feet, providing a storage capacity of 31 acre-feet. The primary purpose of Laird Dam is to safeguard against erosion and maintain a stable environment for fire protection, livestock, and small fish pond activities.
Despite its low hazard potential, Laird Dam is considered to have moderate risk (3) due to its lack of a condition assessment and emergency action plan. The dam features an uncontrolled spillway with a width of 10 feet and a maximum discharge of 3 cubic feet per second. While it does not have outlet gates or associated structures, Laird Dam plays a crucial role in managing water resources within the region and supporting the local ecosystem.
As a private-owned structure, Laird Dam falls under the jurisdiction of the Rock Island District. With no state regulation, inspection, or enforcement, the maintenance and operation of the dam rely solely on the owners. Water resource and climate enthusiasts can appreciate Laird Dam for its contribution to environmental conservation and its role in sustaining water supply for various purposes in Macon County.
