IT Services in Elizabeth Lake, CA

Known then as “La Laguna de Chico Lopez”, Elizabeth Lake was a watering locale on Spanish colonial and Mexican El Camino Viejo in Alta California and the Gold Rush era Stockton-Los Angeles Road. From 1858 to 1861 it was between the Widow Smith’s Station and Mud Spring stage stops of the Butterfield Overland Mail. The lake area was to the west of Rancho La Liebre, an 1846 Mexican land grant now part of Tejon Ranch.

In 1907 William Mulholland, superintendent of the Los Angeles Department of Water and Power, started work on the Elizabeth Lake Tunnel for transporting water in the Los Angeles Aqueduct from Owens Valley to Los Angeles. The 5-mile-long (8 km) tunnel is 285 feet (87 m) under the valley floor. The tunnel was driven from both ends. The north portal is at Fairmont Reservoir and the south in Bear Canyon (now Portal Canyon) northwest of Green Valley. This 11-foot-wide (3.4 m) tunnel was driven 27,000 ft (8,200 m) through solid rock and met in the center within 1½ inches in line and 5/8 inches in depth. Work was around the clock and averaged about 11 feet (3.4 m) per day. The Elizabeth Lake tunnel was the largest single construction project on the Los Angeles Aqueduct and set speed records in its day.
