Darrah No. 2 is a privately owned earth dam located in Cody, Wyoming, along the East Fork Carter Creek. Completed in 1914 for irrigation purposes, this structure stands at 32 feet in height and spans 210 feet in length. With a storage capacity of 290 acre-feet and a surface area of 8 acres, it serves as a vital resource for water management in the area.

Despite its age, Darrah No. 2 has been regulated, inspected, and enforced by the State of Wyoming, ensuring its safety and functionality. The dam's condition assessment in 2018 reported it as poor, with a low hazard potential and moderate risk level. While the dam has a single valve outlet gate, no associated structures, and an uncontrolled spillway, it continues to play a crucial role in supporting local irrigation needs.

Considered a historic landmark within the region, Darrah No. 2 remains a key element in the water resource infrastructure of Park County, Wyoming. As climate change impacts continue to influence water availability and demand, the maintenance and monitoring of dams like Darrah No. 2 are essential to ensure the sustainable management of water resources for future generations.
