It is regularly inspected every 6 years, with the last assessment conducted in September 2015. The surrounding area is monitored for any potential risks, and emergency preparedness measures are in place to address any unforeseen events.

As water resource and climate enthusiasts, understanding the infrastructure and condition of dams like Duvall #1 is crucial for ensuring their continued safe and efficient operation.
