This drawing reveals another flash of John Eastwood's genius, a design for prestressed concrete transmission towers, rather than the traditional wooden or steel poles. Such concrete towers were not used at Big Creek, but have been experimented with elsewhere in recent years.

The prominent granite dome that towers over the site of Big Creek #1 Hydro Plant was named by John Eastwood for William G. Kerckhoff, and early investor in Eastwood's power projects. Kerckhoff became the President of the San Joaquin Light and Power Comany, which grew out of Eastwood's original San Joaquin Electric Company.

John Samuel Eastwood (1857-1924) was involved in civil engineering projects in the San Jaoquin Valley and the High Sierras for almost all of his career. In addition to the Big Creek Project, the invention of the multiple-arch dam is Eastwood's most enduring legacy.
