Egg Milking Question at Trout Run

I see they put the egg rearing station up at Trout run.  My question is where they do put the fish after milking the eggs and sperm out of them?  Do they take them up stream or where?

I have watch Commission employee putting fish in Walnut Creek Channel, Rick Road, and Whitman's Bridge. I even saw them chainsaw a hole in the frozen Walnut Creek Marina Basin and channel. I am sure they have other locations as well. Of course, replanting steelhead requires water which is short supply right now.
