Abstract
A radial or taintor gate utilized to control the flow of water to a turbine is provided with an independently movable flap-gate which is operable to control the release of small incremental amounts of water to flow to the turbine as required, such as speed synchronization; the large radial gate can be maintained closed until such time as synchronization of the turbine has been achieved.
