Steelheadude,

I agree with Bankwalker that your fish is more likely a summer run. It does have that "Skamania" look to it, and you said the eggs were "under developed" or immature. That is an indication of a summer run. I've caught early winter runs that begin showing up in October (almost here), and even then they contain eggs that are more mature than summer runs that I've caught during the same week or month.

Sincerely,

Salmo g.
