Elkhorn, also known as Little Sandy Lake, is a privately owned irrigation dam located in Farson, Wyoming. Built in 1911, this earth dam stands at a height of 15 feet and serves multiple purposes including fire protection, stock watering, and small fish pond maintenance in addition to irrigation. The dam has a storage capacity of 2073 acre-feet and covers a surface area of 145 acres, drawing water from the Little Sandy Creek for its operations.

Despite its historical significance, Elkhorn is facing challenges with a poor condition assessment as of its last inspection in 2017. The dam's hazard potential is rated as low, but its risk assessment is moderate, indicating a need for attention and potential improvements to ensure its long-term safety and functionality. With a valve as its outlet gate and an uncontrolled spillway type, Elkhorn plays a crucial role in water management in the region and requires regular inspections and maintenance to continue serving its intended purposes effectively.

Located in Sublette County, Wyoming, Elkhorn provides valuable water resources for irrigation and other uses in the area. As climate change impacts water availability and usage patterns, the maintenance and upkeep of structures like Elkhorn become increasingly crucial for sustainable water management in the region. With its historical significance and important role in water resource management, Elkhorn represents a key piece of infrastructure for both current and future water enthusiasts and climate advocates to monitor and support.
