Glendo Dike No. 1, located in Casso, Guernsey, Wyoming, is a federally-owned structure designed by I.J. Matthews and completed in 1957 for flood risk reduction along the North Platte River. This earth dam stands at a height of 46 feet and has a storage capacity of 23,320 acre-feet, making it a critical infrastructure for managing water resources in the region. The dam also serves purposes such as hydroelectric power generation and irrigation, highlighting its multifaceted role in water management.

Managed by the Bureau of Reclamation, Glendo Dike No. 1 is subject to state regulations and inspections, ensuring its structural integrity and compliance with safety standards. Despite being classified as a high hazard potential structure, the dam is assessed as being in moderate risk condition. In 2016, the foundation of the dam was modified to enhance its resilience. With a capacity to discharge up to 21,535 cubic feet per second and an uncontrolled spillway type, the dam plays a crucial role in mitigating flood risks and protecting downstream communities along the North Platte River.

As a key component of the water infrastructure system in Wyoming, Glendo Dike No. 1 exemplifies the intersection of engineering, environmental stewardship, and climate resilience. With its strategic location and design features, the dam contributes to the sustainable management of water resources while addressing the challenges posed by a changing climate. As the need for effective water management solutions grows, structures like Glendo Dike No. 1 play a vital role in safeguarding communities and ecosystems in the face of evolving environmental conditions.
