Guys you need to go read the link. HSB can and have reproduced in ponds somewhat like that described. Rock with flowing water and relatively cool water. They are not sterile. See Dave Willis description of functional sterility and the HSB spawning in Stubby's pond. The HSB can also back cross with parentals.

GS in a LMB pond is IMO a 50-50 proposition. I have seen in go wrong in both directions - LMB reproduction completely negated and down through no GS left out of a sustaining population in the other extreme.

Depending on stocking #s and size I would try to use near adult WE (6-10 inches) in year 2. Numbers depending on what else is stocked.
