Paddy No. 2, located in Niobrara, Wyoming, is a private earth dam constructed in 1963 by JOHN A LAMBERT for fire protection, stock, and small fish pond purposes. This dam on S Paddy Draw has a height of 25 feet, a hydraulic height of 19 feet, and a structural height of 30 feet, with a storage capacity of 84 acre-feet. The dam's spillway is uncontrolled with a width of 45 feet, and it is equipped with one valve outlet gate.

Despite its low hazard potential, Paddy No. 2 is currently in poor condition as of the last inspection in May 2018. The dam's risk assessment indicates a moderate risk level (3), and it is under the jurisdiction of the Wyoming State Engineer's Office for regulation, permitting, inspection, and enforcement. Given its importance for fire protection and water resource management in the region, efforts may be needed to address the dam's poor condition and ensure its continued effectiveness in mitigating risks and supporting local ecosystems.

For water resource and climate enthusiasts, Paddy No. 2 serves as a vital structure in the management of water resources in the area. Its location in Edgemont, SD, and association with the Omaha District of the US Army Corps of Engineers make it a key asset for local stakeholders and agencies. With proper maintenance and management, Paddy No. 2 can continue to fulfill its role in providing essential water storage for fire protection, livestock, and wildlife while minimizing risks associated with potential dam failures.
