Trabing, a privately-owned irrigation structure located in Johnson, Wyoming, plays a crucial role in water resource management in the area. Completed in 1971, this earth dam stands at a height of 26 feet and has a storage capacity of 199 acre-feet. Its primary purpose is irrigation, but it also serves for fire protection, stock, and small fish pond purposes. The dam is situated on the Trabing Draw, with the Omaha District overseeing its operations.

Despite its low hazard potential, Trabing's condition assessment is rated as poor, with the last inspection in July 2019 highlighting areas for improvement. The dam's spillway type is uncontrolled, with a width of 40 feet, and it features a slide gate for outlet control. While the risk assessment is moderate, with a rating of 3, there are no specific risk management measures mentioned in the available data. Overall, Trabing presents an intriguing case study for water resource and climate enthusiasts, showcasing the complexities and challenges of managing irrigation infrastructure in a changing climate landscape.
