The only dates we have now are in June- all 3 weeks.
I asked Jim about the fishing in June. Other than King Salmon starting in mid June, I wanted the rundown on rainbows. I didn't want to get the estimates wrong. Here's what he wrote:
My largest was 13 pounds. The average was easily between 6 and 8 lbs on the smolt migration. However, there were lots of other places to fish where the average was a more normal size. We fished the rapids, where the fish were more like 2-5 pounds, and over at Brooks, where you saw that size range. The difference at Brooks in early season is that they might be taking dry flies all day, or small nymphs just under the surface.
As for numbers, that is a tough one. It changed a lot, depending upon the weather. I would feel comfortable stating that an angler will get the chance to sight cast to dozens, if not a hundred or more, trophy rainbows feeding on the surface pretty much every day. If they are quick enough and accurate enough, they will be succesful. I had some fly casters that were not good enough to make that cast consistently. They still loved it but they weren't killing them. I did quite well whenever I did it myself.
It was an easier task with spinning gear. I am confident that with a selection of minnow imitations (jigs, spoons and Yo-Zuri crankbaits) almost anyone could catch several trophy rainbow.
Hope that isn't too long winded. I wouldn't want anyone coming thinking that catching trophy rainbows is a piece of cake. I don't think that is the case anywhere. I want anglers that are thrilled when they land a single 8Lb bow, and anything after that is gravy.
