Little Boxelder No. 3 is a privately owned irrigation dam located on Little Boxelder Creek in Converse, Wyoming. Completed in 1955, this earth dam stands at 30 feet in height and spans 395 feet in length, with a storage capacity of 74 acre-feet. Despite its low hazard potential, the dam is currently rated as being in poor condition, with the last inspection conducted in August 2018 revealing the need for maintenance and repairs.

The dam features an uncontrolled spillway with a width of 55 feet and is equipped with a single slide (sluice gate) outlet gate. While the risk assessment classifies the structure as having a moderate risk level, the overall condition assessment highlights the urgent need for improvements to ensure the safety and effectiveness of the dam. With the potential for climate change impacts on water resources in the region, it is crucial to address the maintenance issues and implement risk management measures to safeguard the surrounding community and ecosystem from any potential failures or disasters associated with Little Boxelder No. 3.
