Haines is a privately owned irrigation dam located in Carbon County, Wyoming, specifically in the city of Saratoga. Built in 1912, this earth dam stands at a height of 20 feet and has a storage capacity of 564 acre-feet. Primarily used for irrigation purposes, Haines is regulated and inspected by the Wyoming State Engineer's Office, ensuring its safety and compliance with state regulations.

Despite its low hazard potential, Haines is currently assessed to be in poor condition, with a moderate risk rating of 3. Its spillway is uncontrolled, with a width of 6 feet, and the dam has not been modified in recent years. The last inspection was conducted in May 2020, with a scheduled inspection frequency of every 5 years. While the dam is considered to be in poor condition, it continues to serve its purpose of providing water for irrigation in the region.

For water resource and climate enthusiasts, Haines presents an interesting case study of an aging irrigation dam in Wyoming. The dam's location on North Spring Creek offstream and its stone core and soil foundation add to its unique characteristics. With its historical significance dating back over a century, Haines serves as a reminder of the importance of maintaining and monitoring the condition of infrastructure to ensure the safety and efficiency of water resources in the face of changing climate conditions.
