Welcome to the forum Anthony, there are alot of variables in getting trout to spawn naturally, but it's sure worth a try if you have enough cool water flow.
What is your water source?,they really need a good flow to aerate the eggs and if you can get them, small rounded river rock to line your stream with.
Another problem is if you have too many small predators in the stream that will eat the eggs and fry, so some type of dam to keep the pond fish from going up the stream eating your fry.

Good luck and let us know of your progress.
