Shadow Mountain, also known as the North Fork Diversion Dam, is a federal-owned structure located in Grand County, Colorado. This irrigation dam was completed in 1945 by the Bureau of Reclamation and serves the primary purpose of providing water for irrigation in the area. It is situated on the Colorado River and has a high hazard potential due to its 63-foot structural height and 37-foot hydraulic height.

With a storage capacity of 18,369 acre-feet and a surface area of 1,852 acres, Shadow Mountain plays a crucial role in managing water resources in the region. The dam features a controlled spillway with a width of 40 feet and is inspected regularly by the Bureau of Reclamation to ensure its safety and proper functioning. Despite its high hazard potential, the dam's risk assessment is categorized as very high, highlighting the importance of ongoing risk management measures to protect nearby communities and infrastructure from potential flooding events. For water resource and climate enthusiasts, Shadow Mountain represents both the challenges and opportunities associated with managing water infrastructure in a changing climate.
