Lake Alajuela is a man-made reservoir on the Chagres River in Panama, formed by the Madden (Alajuela) Dam and used to regulate water for the Panama Canal and municipal supply. It lies in the Canal watershed north of Panama City.

The reservoir and surrounding forested hills are used for fishing, boat travel and limited recreation; forested shores provide habitat for birds and other wildlife. Roadside viewpoints along the dam and reservoir give clear views of the water and adjacent protected forest.

The lake was created when the Madden Dam was completed in the 20th century to control the Chagres River for the Panama Canal and to provide a water supply; the reservoir has been managed as part of canal operations since its formation.

Lake Alajuela sits north of Panama City in central Panama, within the Panama Canal watershed, and is accessible by road from the canal zone and nearby towns.

• Canal and water supply role: The reservoir is part of the Panama Canal watershed and is used to store and release water for canal operations and to supply freshwater to Panama City.

What to See#

• Madden/Alajuela Dam: Madden Dam (also called Alajuela Dam) impounds the Chagres River and created the reservoir used to regulate water for the Panama Canal and municipal supply.

From Panama City: drive via the Centennial Bridge and the Panamericana (Interamericana) toward Gamboa; Lake Alajuela (Madden Lake) is north of the canal and visible from several lookout points and side roads. Organized tours to the canal watershed often include transfer details.
