History

Construction of the Lake Hemet Dam began on January 6, 1891, by the Lake Hemet Water Company. Construction was completed in 1895. When built, the Lake Hemet Dam was the largest solid masonry dam in the world at a height of 122.5 feet (37.3 m) until it was surpassed in height by the Roosevelt Dam in 1911. In 1923, the height of the dam was increased to 135 feet (41 m). The Lake Hemet Municipal Water District was founded on September 27, 1955, to take over the activities of the Lake Hemet Water Company, purchasing the Lake Hemet water system with funds raised through a bond initiative.

The dam was constructed with Portland cement due to its ability to set underwater; however, Portland cement was not available in the western United States at the time of construction. The cement needed for the construction of the dam was purchased from sources in Antwerp, Belgium, shipped around the south of South America, as the Panama Canal had not yet been built. It was then shipped by railroad to San Jacinto where it was loaded onto mule-drawn wagons to be transported up the mountain.[2]
