Lumot River Dam is an embankment dam located between the towns of Cavinti and Lumban, in the province of Laguna, Philippines. The dam was constructed across Lumot River creating a reservoir now known as Lumot Lake or Sierra Lake. Lumot Lake provides additional water through a Bell-mouth spillway and tunnel to Caliraya Lake, which in turn serves as the upper reservoir for the Kalayaan Pumped-Storage Hydroelectric Plant.[1]
