The old Don Pedro Dam still exists at Don Pedro Lake. Some 220’ under the water of a full lake, the old Don Pedro Dam is 1.5 miles upstream from the current dam’s location. Completed in 1923, it was, at the time, the world’s largest concrete gravity dam. The lake created by the old dam, with its storage capacity of 289.000 acre feet, was only 14% of the capacity of the current lake.
