PROBLEM TO BE SOLVED: To provide a method of controlling the start of a dust collector capable of preventing the dust collector from being failed due to the delay of dust removing treatment and the resulting reduction in quantity of water intaken and an operation at a capacity exceeding the dust removing capacity. SOLUTION: The dust collector 3 for removing foreign matter is installed on the downstream side of a screen 2 which is installed along the full width of a water channel 1, and a detector 5 is installed on the upstream side of the screen 2. The dust collector 3 is connected to a unit part 4 for controlling the start of the dust collector. The determination part of the unit part 4 prepares the detection data which indicates the estimated amount of the foreign matter captured by the screen 2 on the basis of the frequency of the detection of the foreign matter by the detector 5, determines whether the captured amount of the foreign matter exceeds a predetermined threshold or not, and transmits a start instruction to the dust collector 3 for starting the dust collector.
