Completed in 1962, this structure serves primarily for recreational purposes, providing a storage capacity of 5,150 acre-feet and a normal storage level of 2,575 acre-feet. With a surface area of 1,610 acres, the dam stands at a height of 6.4 feet and has a controlled spillway width of 15 feet.
Despite its low hazard potential and satisfactory condition assessment, the Coldwater Lake Level Control Structure poses a very high risk due to its location and the potential impact of a failure. Although no associated structures or outlets gates are present, the dam is subject to regular inspections with an inspection frequency of 5 years, with the last inspection conducted in October 2019. The structure is not regulated or permitted by the state and has no emergency action plan in place, raising concerns about its risk management measures and preparedness for potential emergencies.
For water resource and climate enthusiasts, the Coldwater Lake Level Control Structure serves as a reminder of the importance of maintaining and monitoring dams for both recreational and safety purposes. As climate change continues to impact water resources and infrastructure, ensuring the resilience and reliability of such structures becomes increasingly vital in safeguarding communities and the environment. The risk assessment and management of dams like Coldwater Lake highlight the need for proactive measures to address potential hazards and strengthen emergency preparedness in the face of evolving environmental challenges.
