growing wild rice

Hello,

Just wondering if anyone has grown wild rice?

I have a clean mountain stream that runs right through one of my garden areas and I am wanting to try growing wild rice.

I know I will have to create a still-ish paddle deep space to plant. However how do I best replicate their natural lake bottom?

thank you!

I saw a discussion here:
