Two connected man-made lakes (Lake Lumot and Lake Caliraya) were built by American engineers in 1943 to supply water to the Caliraya Hydroelectric Plant. As the dams were constructed, entrepreneurs with foresight created two adjacent communities which were envisioned to be ecological communities, where one can enjoy the beauty and richness of unspoiled nature. The results were man-made mountain lakes complete with coves and sandbars - Lake Caliraya and Lake Lumot. The Americans also seeded the lake with Largemouth Black Bass imported from the US, which continues to proliferate and provide game fishers with year-round weekend excitement.
