Granite Springs, also known as Cheyenne #2, is a historic masonry dam located in Laramie, Wyoming, serving as a crucial water supply source for the city of Cheyenne. Completed in 1904, this architectural marvel stands at a height of 90 feet and has a storage capacity of 5,780 acre-feet. Situated on Middle Crow Creek, the dam's primary purpose is to ensure reliable water access for the region, with a drainage area of 28.4 square miles and a maximum discharge rate of 29,800 cubic feet per second.

Despite its age, Granite Springs has been well-maintained, with regular inspections and a fair condition assessment as of June 2017. The dam features an uncontrolled spillway, two other controlled outlet gates, and a high hazard potential due to its critical role in water supply management. With a moderate risk assessment rating, ongoing risk management measures are in place to mitigate any potential hazards and ensure the safety and functionality of the structure. As a key infrastructure asset in the region, Granite Springs plays a vital role in water resource management and climate resilience efforts in Wyoming.
