The Crystal Springs Dam was designed by Herman Schussler Chief Engineer of the Spring Valley Water Company. The concrete dam was constructed by using large blocks poured separately and allowed to set before adjoining blocks were poured. The unique feature of this dam is the fact that none of the horizontal or vertical joints match up. Mr. Schussler was also very demanding that the concrete be batched in the exact proporations of his mix design. Although this dam was erected about 100 yards east of the San Andreas fault line and was subject to severe shaking it did not leak a drop. The attached photographs show the unique joint configuration and the completed dam.
