Lake Alajuela (Spanish: Lago Alajuela) is an artificial lake in the Chagres River basin. The lake is bounded by the Madden Dam and linked to the Panama Canal. Lake Alajuela serves as a reservoir for the canal, which lies to the lake's southwest. It was created in 1935. The Chagres, Pequení, Boquerón, Salamanca, La Puente, Indio, Piedras, San Cristóbal and Escandaloso rivers flow into the lake. The rivers of Lake Alajuela contribute 45 percent of the total water for the canal.
