A dredger for collecting deposit in a river is provided to filter water collected with the deposit and to discharge clean water, thereby preventing contamination of the river during a deposit collection operation. A dredger for collecting deposit in a river includes a fork(4), a first suction pipe, a main suction pipe(5), first and second dredge tanks(9,10), a first hopper(16), a second hopper(19), a first dry conveyor(28), a second dry conveyor(30), a first discharge conveyor(33), and a second discharge conveyor(34). The fork is coupled to an end of an arm(3) of an excavator(2). The first suction pipe includes a plurality of suction hoses disposed around the fork to suck deposit. The main suction pipe is connected to the first suction pipe to suck the deposit into the first and second dredge tanks. Water and fine components in the deposit are collected in the second hopper. The deposit is dried on the first and second dry conveyors. Small deposits and impurities are discharged by the first discharge conveyor, and large deposits and impurities are discharged by the second discharge conveyor.
