Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Encouraging trout spawning with pond circulator.

I have been working towards this very same end goal. I don't like having to rely on the fish man. Mark Cornwell did an article in a back issue of the PB magazine that showed how to build spawning boxes for Brook Trout. Very good issue. You can buy back issues of the mag off of the website. I think it would be extremely easy to do especially if you have access to electricity. Unfortunately, I have no electricity close to the lake I'm working on.
