The dam has a maximum storage capacity of 6,800 acre-feet and a normal storage capacity of 1,408 acre-feet, making it a significant structure in the region.

With a controlled spillway and vertical lift outlet gates, Fallen Leaf Lake Dam is designed to manage water flow effectively and safely. The dam's hazard potential is rated as significant, and it has a very high risk assessment level. Despite being constructed in the early 20th century, the dam has been modified in 1994 to ensure its structural integrity and safety. The last inspection of the dam was conducted in 2015, with its condition currently listed as "Not Rated."

Managed by the Forest Service, Fallen Leaf Lake Dam stands as a crucial infrastructure for water resource management in the area. Its strategic location on Taylor Creek and its key role in flood risk reduction highlight its importance in sustaining the local ecosystem and providing recreational opportunities for visitors. As climate change continues to impact water resources, the maintenance and monitoring of dams like Fallen Leaf Lake Dam become increasingly vital for ensuring the safety and sustainability of our water systems.
