The North Crow Diversion is a crucial water supply structure located in Laramie, Wyoming, designed to divert water from the North Fork of Crow Creek for various purposes, primarily water supply. Completed in 1910, this arch dam stands at a height of 46 feet and has a maximum storage capacity of 4,000 acre-feet. It serves the local government and is regulated by the State of Wyoming, with inspections conducted regularly to ensure its fair condition.

The dam's significant hazard potential and moderate risk assessment highlight the importance of proper risk management measures and emergency preparedness. Despite its age, the North Crow Diversion continues to play a vital role in the water resource infrastructure of the region, providing water for agricultural, municipal, and industrial needs. With its uncontrolled spillway and stone core foundation, this historic structure remains a key component of water management in the area, demonstrating the importance of maintaining and monitoring aging dams to ensure public safety and water availability in a changing climate.

As climate change continues to impact water resources, the North Crow Diversion serves as a reminder of the critical role that infrastructure plays in managing water supply and mitigating the effects of a changing climate. With its location in the North Fork of Crow Creek and close proximity to Cheyenne, this dam underscores the importance of sustainable water management practices and the need for ongoing monitoring and maintenance to safeguard water resources for future generations.
