This report is the eighth in a continuing series of progress reports giving the results of discharge measurements made at selected springs and streams in the Tecolote Tunnel area of the Santa Ynez Mountains. The measurement program was begun on its present scale in the latter part of 1948 by the U. S. Geological Survey at the request of the U. S. Bureau of Reclamation and has been continued under a cooperative agreement with the Santa Barbara County Water Agency since July 1, 1949, under which each agency pays half the cost of the investigation.
The purpose of the program is to obtain factual data to assist in determining what effect, if any, the inflow of ground water into Tecolote Tunnel will have on surface-water resources in the vicinity of the tunnel. The area involved in the program, shown on plate 1, was made large enough to include a number of springs and streams believed to be outside the zone of influence of the tunnel. Tecolote Tunnel, completed in March 1956, was built by the Bureau of Reclamation for the purpose of conveying water from Cachuma Reservoir to the city of Santa Barbara and adjacent coastal communities. The alinement of the tunnel is essentially north and south through the center of a region that extends from the Painted Cave area on the east to Refugio Pass on the west and from the Santa Ynez River on the north to the Pacific Ocean on the south. Storage, in Cachuma Reservoir began November 16, 1952. Roads within the area covered by Cachuma Reservoir have been relocated since plate 1 was prepared.
The purpose of this progress report is to make available the factual data obtained from July 1956 to June 1958.
