Twombley is a privately owned irrigation dam located in Weld County, Colorado, along the South Platte River. Built in 1931, this Earth-type dam stands at a height of 13 feet and spans a length of 630 feet, with a storage capacity of 76 acre-feet. While the dam has a low hazard potential, it is considered to have a high risk level, emphasizing the need for proper risk management measures.

Despite being last inspected in 1984, with a frequency of every 6 years, Twombley's condition assessment is currently marked as "Not Rated." This raises concerns about the structural integrity of the dam and highlights the importance of regular inspections and maintenance. Furthermore, with a risk assessment indicating a high risk level, there is a pressing need for updated emergency action plans and risk management strategies to ensure the safety and stability of the dam and surrounding areas.

With its historical importance in irrigation and water resource management, Twombley serves as a vital infrastructure for agricultural activities in the region. However, in order to mitigate potential risks and ensure the long-term functionality of the dam, there is a need for increased attention and investment in its maintenance, monitoring, and emergency preparedness. As climate change continues to impact water resources, it is crucial to prioritize the safety and sustainability of structures like Twombley to safeguard both the environment and the communities that rely on them.
