The work on the second dam, which replaced the first, wooden structure, began in October 1906 (see Evening Standard 1/10/1906, page 4) and the water was turned on in August 1907 (E.S. 3/03/1909, page 5). In 1912, its height was raised to 50 feet, the enlarged dam being officially opened on February 17, 1913.
