Planning temperature control procedures for the mass concrete of Detriot Dam in western Oregon is explained in detail. Construction methods, including cooling practices, are given, along with cement types and proportioning of the concrete. Temperature history of the mass concrete supplements the analysis of temperature strains in each of four zones of the dam. Uniformly stable conditions were established at the base of the dam, and inspection 3 years after completion disclosed no defects on the outside surface, and only a few hairline cracks on exposed interior surfaces. Total rest of cooling measures was $0.63 per cu yd, about 4 percent of the total cost of mass concrete.
