Nienhuser, located in Lincoln, Colorado, is a privately owned dam that serves multiple purposes, including fire protection, stock, and small fish pond irrigation. Built in 1924, this earth dam stands at a height of 14 feet with a length of 690 feet, providing a storage capacity of 62 acre-feet. The dam is situated on Lake Creek-TR and falls under the regulatory oversight of the Colorado Department of Water Resources.

Despite being rated as having a low hazard potential, Nienhuser faces a high risk level due to its condition assessment not being rated and lacking certain emergency preparedness measures. The dam has not been inspected since 1988, which raises concerns about its current structural integrity and safety. While the risk management measures and guidelines for emergency action plans are not reported, it is crucial for water resource and climate enthusiasts to monitor and advocate for proper maintenance and monitoring of Nienhuser to ensure the safety of the surrounding community and ecosystem.

With its historical significance and importance for water management in the area, Nienhuser serves as a reminder of the need for regular inspections, maintenance, and emergency preparedness for dams. As climate change continues to impact water resources, it is imperative to prioritize the safety and sustainability of such infrastructure to mitigate risks and ensure the resilience of water systems in the face of evolving environmental challenges.
