Hansen is a privately owned irrigation dam located in Carbon County, Wyoming, along Fillmore Creek. Built in 1922, this earth dam stands at a height of 16 feet and has a storage capacity of 351 acre-feet. Despite its low hazard potential, Hansen's condition assessment is rated as poor, indicating a need for maintenance and improvement to ensure its long-term functionality.

The dam features an uncontrolled spillway and a single valve outlet gate. Its primary purpose is irrigation, serving the local agricultural community for water supply. Although the structure is regulated and inspected by the Wyoming State Engineer's Office, its last inspection in September 2020 revealed a poor condition, highlighting the importance of ongoing monitoring and maintenance to mitigate risks and ensure the safety of downstream communities.

With a moderate risk assessment score of 3, Hansen presents a manageable but not negligible level of risk. It is essential for stakeholders and regulators to prioritize necessary repairs and upgrades to improve the dam's overall condition and resilience to changing climate conditions. By addressing the identified deficiencies and implementing risk management measures, Hansen can continue to support water resource management in the region effectively.
