Anderson is a private irrigation dam located in Carbon County, Wyoming, specifically in the city of Saratoga. Built in 1931, this Earth-type dam stands at a height of 28 feet and has a hydraulic height of 23 feet, with a length of 1600 feet. The dam serves the primary purpose of irrigation, with a storage capacity of 361 acre-feet and a surface area of 4 acres. The dam is situated on Otto Creek, a tributary of Cow Creek, and is regulated and inspected by the Wyoming State Engineer's Office.

Despite being categorized as having a low hazard potential, the condition assessment of Anderson dam is rated as poor, with the last inspection conducted in September 2017. This assessment raises concerns about the safety and structural integrity of the dam, especially considering its moderate risk assessment level. The dam features an uncontrolled spillway with a width of 100 feet and an outlet gate for water release. With a history of modifications and a need for improved risk management measures, Anderson dam serves as a critical site for water resource and climate enthusiasts to monitor and advocate for necessary upgrades and maintenance.
