German Brown trout, that is.

I am looking through the plant plan, and I notice that there is an absence of mature (catchable) brown trout in my area. I see where fry are planted in some Thurston County lakes, but no catchables.

Anybody have any ideas as to why they are planting the fry, but not the catchables? Thanks in advance.

The only browns I have caught were in Pass lake, Green Lake (King County), and a secret lake in Eastern WA. Cool looking fish, just would like to get more chances to catch them.
