if there are a bunch of fish around that size limit, they may be from the 2002 year class of fish that broke the drought years of reproduction lack. I'm not familiar with growth rates but maybe you can use this davy. I have also seen reproductivly active fish at that size too.

I will look into finding some data on growth rate on that stream. If there is none maybe I can work on that.

No barbless regs on the NF.
