Hermine, located in Casper, Wyoming, on Bates Creek, is a privately owned irrigation dam completed in 1912. With a height of 12 feet and a storage capacity of 174 acre-feet, Hermine plays a crucial role in water management for the surrounding area. The dam is regulated and inspected by the Wyoming State Engineer's Office, ensuring its safety and compliance with state regulations.

Despite being classified as having low hazard potential and being in fair condition as of the last assessment in April 2017, Hermine is subject to regular inspections every five years to monitor its structural integrity and functionality. The dam serves primarily for irrigation purposes, highlighting its importance in supporting agricultural activities in Natrona County. Its location within the Sacramento District and under the jurisdiction of state regulatory agencies underscores its significance in water resource management in the region.

With Liz Cheney (R) as the Congressional representative for the area, Hermine stands as a historical landmark that continues to contribute to the local water infrastructure. Its construction over a century ago reflects a commitment to harnessing natural resources for societal benefit, emphasizing the enduring role of dams in sustaining water supply and agricultural production. As water resource and climate enthusiasts, understanding the role and management of structures like Hermine is essential for ensuring the resilience and sustainability of water systems in the face of changing environmental conditions.
