Get past the guards and find the entrance to the generator room.Get to the highest altitude possible using the aircraft.
Fly the aircraft to the jump point over the dam.You're going to need a plane to parachute onto the dam quay In order to complete the mission the player must: With deputies and SWAT closing in with their Rangers and Enforcers from the dam's roadway below, CJ narrowly escapes capture by performing a swan-dive from one of the dam's control towers into the outlet channel to the south (erroneously labeled as Sherman Reservoir by the game). After sneaking into the dam's facilities and planting the explosives, Carl escapes to the roof, only to be trapped by the guards. To do this, Carl heads out to Sherman Dam, which supplies Las Venturas with hydroelectric power, to plant remotely detonated explosives on the main generators.
His next step is to establish a means of temporarily cutting the power supply to Las Venturas in order to provide himself and Wu Zi Mu's men with the cover of darkness and the resulting confusion while robbing the safe. Carl, having successfully convinced Millie Perkins to date him in order to obtain her keycard, is now positioned to continue preparations for the heist on the main vault of Caligula's Palace.
