Jerry -
A couple of times now you have referred to this 15 to 20% wandering factor. Find that interesting and was wondering about the source of the figure?

It is common for steelhead, especially summer steelhead show up in rivers other than their home river however they also often backtrack and end back at "home" to spawn. I'm wondering if the info is the % of a given wild population that spawns in water other than its home? Wonder how that info was determined?
