On June 11, 1958, the final diversion of the Trinity began under the
left abutment of the dam.45 Later that week, crews finished damming the
river by dumping old car bodies and huge rocks into the narrows of the
coffer dam.46 Since then, the river has followed a man-made course. Two
weeks later, construction of the Trinity Dam started.47 Within a month,
crews were working 18-hour days covering the floor of the river with
earthen material delivered from Pettyjohn Mountain by a two-mile long
conveyor belt.48 The conveyor carried 2000 cubic yards of earth an hour
to DW-20's that hauled 32 yard lifts to the dam site where bulldozers
and sheepfoot tampers spread and tamped the material.49 By January 1959,
the Trinity Dam backed up water 74 feet deep at the crest of its first
flood with a flow of 38,000 cfs.50

1958

Dam workers threw auto bodies into the Trinity River to turn the
rambunctious stream from its natural channel into a new manmade channel.
