An excerpt from the article 22 facts about Panama

Gatun Lake in central Panama was created between 1907 and 1913, thanks to the construction of the Gatun Dam and the damming up of the waters of the Chagres River. The lake is the main source of water and the locks that allow ships to pass through the Panama Canal. It stretches 32.7 kilometers and is the main part of the Panama Canal.
