Sundby No. 2 is a privately owned earth dam located in Laramie, Wyoming, along Barkley Creek. Built in 1971 by designer John M Hill, this dam serves primarily for irrigation purposes but also provides fire protection, stock water, and functions as a small fish pond. With a height of 26 feet and a hydraulic height of 21 feet, it has a storage capacity of 45 acre-feet and a surface area of 3 acres.

Despite its low hazard potential, Sundby No. 2 is in poor condition according to its last inspection in 2019. The dam has an uncontrolled spillway with a width of 8 feet and a single valve outlet gate. While the risk assessment categorizes it as moderate, there are no current risk management measures in place. The dam's condition assessment, coupled with its outdated inspection frequency of 5 years, raises concerns among water resource and climate enthusiasts about its long-term sustainability and safety.

Given its crucial role in supporting agriculture and providing water resources in the area, stakeholders may need to prioritize maintenance and upgrades to ensure the structural integrity and functionality of Sundby No. 2. With its location in a scenic part of Albany County, Wyoming, this dam serves as a reminder of the delicate balance between human needs and environmental conservation in the face of changing climate patterns and increasing water demands.
