Partitions or receptacles around the rim of a WATERWHEEL in which the water is held, in order to use its weight to turn the wheel. In cases where a high velocity flow of water is directed into the buckets, some kinetic energy may be converted into useful energy by the wheel. Buckets are fitted to OVERSHOT, BACKSHOT and most BREAST-SHOT wheels. May vary in shape. See also SHROUDS, FLOATS, VENTILATED BUCKET and UNVENTILATED BUCKET.
