This illustrated image provides visual details to the technical terminology names of Oroville's rotating Radial Gates. Lift motors, with cables, on the upper "hoist deck" will lift these massive radial gates to allow water to flow in the Gate Chute openings. The radial gates have inflatable seals along there sides that are hydraulically pressurized to enable a controllable watertight seal. The bottom of the Radial Gate has a compression rubber type of seal that operates by the sheer weight of the Gate compressing it along the bottom edge. Stainless steel "slide plates" are used on the boundary of the radial gate edges, bonded to the concrete column face, to provide a smooth surface for the side seals.
