Despite its low hazard potential and satisfactory condition assessment, Tonkin Springs Tailings Dam is still considered to have a high risk assessment due to its location and potential impact on the surrounding environment. With a drainage area of 0.2 square miles and a maximum discharge of 2 cubic feet per second, the dam poses a potential risk in the event of a breach or failure. Emergency action plans are in place, but there is room for improvement in terms of risk management measures and ensuring compliance with guidelines for emergency preparedness.

Overall, Tonkin Springs Tailings Dam serves a crucial role in the mining industry in Nevada, but its risk assessment highlights the importance of ongoing monitoring and maintenance to prevent any potential disasters. As water resource and climate enthusiasts, it is vital to stay informed about the safety and regulatory measures in place for dams like Tonkin Springs to protect both the environment and local communities from any potential harm.
