Topographical Map of East San Pasqual Valley

This map shows the East end of the San Pasqual Valley along with a layout of the irrigation network that was built by Ray Trussell and his neighbors between 1916 and 1922. Also shown are photos of some of the landmarks that can still be found today. It was built as an improvement over the East San Pasqual Irrigation Ditch. It reduced leakage, reduced maintenance, and increased pressure to downstream users.
