- Madden_Dam abstract "The Madden Dam, completed in 1935, impounds the Chagres River in Panama to form Lake Alajuela, a reservoir that is an essential part of the Panama Canal watershed. The lake has a maximum level of 250 ft above sea level. It can store one third of the canal's annual water requirements for the operation of the locks. Since the reservoir is not part of the navigational route, there are fewer restrictions on its water level.The Madden Dam was built to prevent the occasionally torrential flow of the once wild Chagres River, which flows into the navigational route of Gatun Lake. The river's unruly flow posed a major challenge to the construction of the Panama Canal. Water from the dam's reservoir is also used to generate hydroelectric power and to supply Panama City's fresh water. The dam and the reservoir behind it were both named for U.S. Congressman Martin B. Madden of Illinois, who was a chairman of the House appropriations committee during the period while the U.S. was constructing the Panama Canal. The reservoir, which had been known as Madden Lake from the time the dam first became operational, was renamed Lake Alajuela after the Canal Zone reverted to Panamanian control at the end of 1999.".
