Warner No. 2 is a privately owned irrigation dam located in Converse, Wyoming, along the Five Mile Creek. Built in 1952, this Earth-type dam stands at 23 feet tall and spans 515 feet in length, with a storage capacity of 158 acre-feet. Despite its age, the dam is in poor condition and has a low hazard potential, indicating a moderate risk level.

The dam features an uncontrolled spillway with a width of 100 feet and a single slide (sluice gate) outlet. It is regulated and inspected by the Wyoming State Engineer's Office, with enforcement and permitting responsibilities falling under state jurisdiction. The surrounding area is sparsely populated, with the nearest city being Douglas, and the dam is situated within Congressional District 00, represented by Liz Cheney (R). Water enthusiasts and climate advocates interested in water resource management and dam safety may find Warner No. 2 an intriguing case study for its historical significance and current maintenance challenges.
