The Oroville Dam core block was completed during the summer of 1963. The dam is on the Feather River, near the city of Oroville, in Northern California, and is a key unit of the California Water Plan. The core block is a 293,000 cu yd mass concrete structure, which is located beneath an earth-fill embankment. This paper describes the design, proportioning, production, and placing of concrete for the core block. Testing and temperature instrumentation results are pre-sented to demonstrate what was achieved with the lean, mass concrete placed under generally hot weather conditions.
