Hiser is a private irrigation dam located in Natrona, Wyoming, along the Pine Ridge Draw. Built in 2005, this Earth-type structure stands at 30 feet high with a dam length of 372 feet, providing a storage capacity of 56 acre-feet for irrigation purposes. Despite its low hazard potential, the dam's condition assessment is rated as poor, highlighting the need for maintenance and improvements.

The dam features an uncontrolled spillway and a single valve outlet gate. It is regulated and inspected by the Wyoming State Engineer's Office, ensuring compliance with state permitting and enforcement regulations. With a moderate risk assessment rating, there is a need for enhanced risk management measures to mitigate potential issues and ensure the safety and reliability of the dam for both water resource and climate enthusiasts in the area.

In the event of emergencies, it is crucial for Hiser to have an effective emergency action plan (EAP) in place, although details on its preparedness and compliance with guidelines are currently unavailable. With the last inspection conducted in October 2019 and a scheduled inspection frequency of 5 years, ongoing monitoring and maintenance are essential to address the dam's poor condition assessment and minimize risks associated with its operation.
