Simulation of particles emitting before start up

I’m making a waterfall using particles. When I start the game, the particle system begins to emit, and thus the water begins to fall down. After a few seconds, the entire waterfall is visible. However, I want to be able to see the entire waterfall, as soon as I start the game. Is there a way to make the particle system appear as if it has run for a while before I start up the game?
