32 This is a large relief map of the Central Valley Project showing natural waterways which are pictured in light blue, and man-made waterways which are in dark blue. High voltage transmission lines indicated in red come from Trinity, Shasta, and Folsom Powerhouses into the switchyard at the Tracy Pumping Plant. Each of these lines operates at 230KV (230,000 volts). The Bureau of Reclamation offers tours of the pumping plant to visitors interested in gaining a better understanding of the Central Valley Project
