Well gee Mike, I live overlooking Roosevelt and can walk to Banks in 10 mins.,but I don't fish either one.
It's flies you see that I'm liking to fish and neither one are good "fly" lakes. I fished Banks a few times with hair poppers, but it's mostly an early morning late evening thing...and then it's chancy and the bass are small. I like to fish all day when I go out.
As for most of the rest of the lakes in E.Wash, I been there. Even pioneering fly fishing for trout on O'sullivan Rez. and Moses Lake,both of which are fair "fly" lakes,but I feel sooooo alone.
