White is a privately owned Earth dam located in Greybull, Wyoming, along the White Gulch stream. Built in 1914 for irrigation purposes, this dam stands at a height of 20 feet and has a storage capacity of 201 acre-feet. Despite its age, the dam is well-maintained with a fair condition assessment and a low hazard potential.

Managed by the Wyoming state regulatory agency SEO, White Dam is subject to regular inspections, with the last one conducted in April 2017. The dam features a single valve outlet gate and does not have a spillway, emphasizing its low-risk profile. However, the risk assessment indicates a high risk level, prompting the need for ongoing risk management measures to ensure the safety and integrity of the structure.

In the event of an emergency, the status of White Dam's Emergency Action Plan (EAP) preparation and adherence to guidelines is not specified in the data. With Liz Cheney as the Congressional representative for the area, stakeholders and water resource enthusiasts are encouraged to stay informed about any updates or developments regarding White Dam to ensure the continued sustainability of the irrigation infrastructure in Big Horn County, Wyoming.
