Middle Spring is lower in elevation than the above-mentioned sources and, therefore, its flow of approximately 850 gallons per minute can not be made available without a loss in head. There is a further loss of approximately 260 gallons per minute coming up outside of the well- casing, which probably can not be diverted into the pipe line* econ­omically* The 610 gallons per minute is not an actual loss, except during winter months, as it may be used on the Company's ranch for irrigating purposes, but, as mentioned above, this water can not be made available for Railroad or City use without lowering the head on the main pipe line, which is not desirable, or installing a pump to
