Chief Creek #4, also known as Stalker Lake or Chief Creek Reservoir, is a state-owned fish and wildlife pond located in Colorado's Yuma County, near the city of Wray. Built in 1956, this earth dam stands at 23 feet tall and spans 1,100 feet in length, with a storage capacity of 291 acre-feet. The reservoir covers a surface area of 27 acres and serves as a habitat for various aquatic species in the region.

Managed by the Colorado Department of Water Resources, Chief Creek #4 has a significant hazard potential and is inspected every two years to ensure its structural integrity. The dam's condition was last assessed as satisfactory in May 2019, with a moderate risk rating. While the reservoir does not have a controlled spillway, it has an uncontrolled spillway width of 107 feet to manage maximum discharge rates of up to 1,560 cubic feet per second.

This water resource plays a crucial role in supporting the local ecosystem and provides recreational opportunities for fishing and wildlife observation. With its state-regulated status and emphasis on fish and wildlife preservation, Chief Creek #4 serves as a vital asset in maintaining the environmental balance of the region and ensuring sustainable water resource management practices.
