All patterns will catch fish, but some do produce better than others at certain part of the season. A few years ago, Carlo and Shane's fry patterns definitely caught more bull trout in early April while I drift fished, but I did hook up more steelhead on that particular day.
With the fry count being much lower than other years, the fishing is most likely poor, which has already been reported by a few other members. Bull trout are opportunists, which are highly mobile and tend to congregate at where the food is, so as Chrome Mykiss has mentioned, it is advantageous to cover as much water as possible until you find a school of feeding fish.
I can't provide much more than this as I have only fished the river once.
On a different note, vulture9 yesterday we deleted 5 of 7 topics that you started within a short period of time. The ones deleted were repetitive and generic. As Chrome Mykiss has mentioned, most of these questions have already been answered in the past. While we don't wish to discourage new members from asking questions, the best thing to do is to perform
a search in the forum. If the search comes up with nothing, then please feel free to post away. It is only considerate to keep our topic count moderate so other members also have a chance to have their questions answered, and it also makes the reading much easier for everyone.
I understand new members are eager to read the report section, but we would like to see members contribute mutually to maintain the quality of the forum content. What we don't want to see is to have people posting rapidly to boost their post count and gain access, then stop posting and simply read the reports from that point.
