Nofstger, also known as Harrison Reservoir, is a privately owned dam located in Routt County, Colorado. Built in 1908, this earth dam stands at a height of 16 feet and serves primarily as a Fish and Wildlife Pond. With a storage capacity of 91 acre-feet and a surface area of 13 acres, Nofstger plays a crucial role in fire protection, stock maintenance, and habitat preservation for small fish and wildlife in the area.

Managed by the Colorado Department of Water Resources, Nofstger is regulated, permitted, inspected, and enforced to ensure its safety and functionality. Despite being classified as having a low hazard potential, the dam's condition assessment in 2015 was deemed unsatisfactory, highlighting the need for maintenance and potential rehabilitation measures. The risk assessment for Nofstger indicates a moderate level of risk, emphasizing the importance of ongoing monitoring and management to mitigate any potential hazards.

Located in the city of Hayden, Nofstger's proximity to the Grassy Creek-TR river/stream system underscores its significance in the local ecosystem. As a point of interest for water resource and climate enthusiasts, Nofstger serves as a reminder of the delicate balance between human infrastructure and environmental conservation, highlighting the interconnectedness of water resources and climate resilience in a rapidly changing world.
