The dam is regularly inspected, with the most recent inspection taking place in December 2020. Despite its high hazard potential, the dam's condition is considered adequate for now, meeting safety guidelines and ensuring that emergency preparedness protocols are in place if needed.

With its strategic location and vital role in water supply and management, Mcguire stands as a key infrastructure asset in California's water resource landscape. As climate change continues to impact water availability and quality, dams like Mcguire will play an increasingly crucial role in ensuring water security for the region's residents and ecosystems. The ongoing monitoring and maintenance of Mcguire demonstrate a commitment to safeguarding this essential water resource for current and future generations.
