Seventh progress report on the cooperative investigation of springs and streamflow in the Tecolote tunnel area of Santa Barbara County, California
This report is the seventh in a a continuing series of progress reports giving the results of discharge measurements made at selected springs and streams in the Tecolote Tunnel are area of the Santa Ynez Mountains. The mountains. The measurement program was begun on its present scale in the latter part of 1948 by the Geological Survey at the request of the Santa Barbara County Water Agency and is being continued under a cooperative agreement whereby each agency pays half the cost of the investigation. The purpose of the program is to obtain sufficient factual data to determine what effect, if any, the inflow of ground water into Tecolote Tunnel will have on the flow of springs and streams in the vicinity of the tunnel. The area involved in the study, shown by plate 1, was made large enough to include a number of springs and steams believe to be outside the zone of influence of the tunnel. Tecolote Tunnel, completed late in 1955, was built by the Bureau of Reclamation for the purpose of conveying water stored in Cachuma Reservoir to the city of Santa Barbara and adjacent coastal communities. The alinement of the tunnel is roughly north and south through the center of the arbitrarily chosen study area which 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. The purpose of this report is to make available the factual data obtained from July 1954 to June 1956, together with a brief presentation of precipitation, springflow, and tunnel outflow for the entire period of investigation.

Fifth progress report on the cooperative investigation of springs and streamflow in the Tecolote Tunnel area of Santa Barbara County, California
This report is the fifth in a continuing series of annual progress reports giving the results of discharge measurements made at more than 120 selected sites in the "Tecolote Tunnel Area" of the Santa Ynez Mountains. This area derives its name from the tunnel now being built by the Bureau of Reclamation for the purpose of diverting the flood waters of the Santa Ynez River as stored in Cachuma Reservoir to the city of Santa Barbara and adjacent coastal communities. The tunnel alignment is roughly north and south through the center of this area, which extends from Refugio Pass on the west to San Marcos Pass and the Painted Cave area on the east. The program of measuring the developed springs and headwater streams in the Tecolote Tunnel area was started on its present scale in the latter part of 1948 at the request of the Santa Barbara County Water Agency. The primary purpose of the program is to obtain sufficient factual data to determine what effect, if any, the construction and use of the Tecolote Tunnel will have on the outflow of the springs in the area. The area covered by this study was made large enough to include all springs that could possibly be affected by the tunnel, as well as springs believed to be outside the zone of influence. The program is being carried on by the Geological Survey under a cooperative agreement with the Santa Barbara County Water Agency whereby each pays one half the cost. Prior to January 1953 the flow at each of the more than 120 locations was generally measured monthly. Since then, the number of sites at which monthly measurements are made has been reduced to about 40, with measurements made every other month or quarterly at the remaining locations. The purpose of this report is to make available the factual data obtained from May 1, 1952 to June 30, 1953.

Fourth progress report on the cooperative investigation of springs and streamflow in the Tecolote Tunnel area of Santa Barbara County, California
This is a continuation of annual progress reports giving the results of discharge measurements made in the Santa Ynez Mountains between Refugio Canyon on the west to San Marcos Pass and the Painted Cave area on the east. This portion of Santa Barbara County has been designated as the "Tecolote Tunnel Area" because a tunnel by that name, now being built by the Bureau of Reclamation, passes through it. The purpose of this tunnel is to divert flood runoff from the Santa Ynez River, stored in Cachuma Reservoir, to the city of Santa Barbara and adjacent areas. During the construction of this tunnel, the seepage from the south portal has averaged 6.4 second-feet for the year ending April 30, 1952, the average being 8.7 second-feet for the last 6 months of that period. Both of these values exceed the average total discharge prior to April 30, 1951, for more than 120 springs measured in the Tecolote Tunnel Area. As, it was not known what effect the seepage from this tunnel might have on the flow of springs and streams in the immediate vicinity, the Santa Barbara County Water Agency requested the U. S. Geological Survey to institute an observational program. This program was started in 1948—about 2 years before work was started on the tunnel. The area covered by the observational program was made sufficiently large to include all the springs that could possibly be affected, as well as certain border springs believed to be outside the zone of influence. The purpose of this, the fourth progress report, is to make available factual data obtained during the year ending April 30, 1952. This program is operated under a cooperative agreement between the U. S. Geological Survey and the Santa Barbara County Water Agency whereby each pays half the cost of the investigation.

Second progress report on the cooperative investigation of springs and stream flow in the Tecolote Tunnel area of Santa Barbara County, California
This report represents the second of a series of progress reports giving the results of discharge measurements made at more than 100 locations in the Santa Ynez Mountains from the Refugio Canyon on the west to the San Marcos Pass and Painted Cave area on the east. The flow in all the developed springs and headwater streams within this area, here designated as the Tecolote Tunnel Area of the purpose of this report, is generally measured monthly. The primary purpose of this second progress report is to make available to the public all factual data regarding the flow at these locations obtained since the preparation of the first progress report, issued in May 1949. Near the mid-point of this area the Bureau of Reclamation and the Santa Barbara County Water Agency proposed a tunnel, known as Tecolote Tunnel, for the purpose of diverting a portion of the runoff of the Santa Ynez River drainage area into water-deficient Santa Barbara and the coastal areas to the east and west, Because the water users of the mountain springs in the Tecolote Tunnel Area are somewhat apprehensive as to the influence this tunnel may have on their present water supply, the Santa Barbara Water Agency has requested the Geological Survey to obtain records of flow in their springs at frequent and regular intervals. During the current fiscal year these observations have been made as a result of a cooperative agreement between the Geological Survey and the Santa Barbara County Water Agency whereby each paid half the cost of the investigation. During the previous fiscal year all the costs to the Geological Survey in obtaining these observations were completely reimbursed by the Bureau of Reclamation.
