Symposium on operation of the Boulder Dam transmission line — General operation of transmission line

THE Boulder Dam transmission line of the Department of Water and Power of the City of Los Angeles, has been in service since October 1936. By virtue of the vagaries of climate, the line has been called upon to withstand lightning, wind, ice, and floods of unusual severity, subjecting the line to many of the extreme conditions for which it was designed, without having to wait the usual long term of years for such conditions to occur.
