Ed Fletcher, co-owner of Cuyamaca Water Company, with an inspection party at Cuyamaca Flume in 1925. Approximately 37 miles long, the flume was built by San Diego Flume Co. 1886-1889, which became the Cuyamaca Water Company in 1910. Redwood lumber was brought by boat to San Diego harbor, cut to lengths and loaded on wagons for the trip inland. A total of 315 trestles carried the flume across valleys, canyons and ravines. The flume's usefulness was replaced with other water sources and now there are very few remnants remaining.
