Hi all, it looks like I need help with my ability to forecast the run size. Unfortunately, I think we have gotten to the point where most of the adult Chinook salmon destined for the Clearwater Region have come over Bonneville Dam. This means our harvest share will likely be somewhere between 4,500 and 5,000 adult fish for the Clearwater River drainage and the Rapid River area. Check out the table below (or click 'read more') to see where these fish are headed for based on PIT tags we have detected at Bonneville Dam.

Fishing effort certainly picked up in the Clearwater River last week with most of it occurring in the Lewiston Area. With most of the effort occurring there, it is not too surprising that this is where most of the fish were caught. As time progresses we will see more and more fish caught upstream. The table below shows where these fish were caught on a weekly basis. One thing all of you can track is as we add on each weeks harvest onto the table below, you will be able to determine how close we are getting to potential closures for the different river sections. Our target adult harvest for each river section is listed in the bottom part of the table below. In case you are wondering how we came up with these different target amounts of harvest for each river section, it came from all of you based on input in public meetings, creel surveys and mail surveys. It is important for all of you to realize that these are only targets and we may need to adjust them based on where the fish are destined and how harvest is going in the different river sections. For example, if anglers in the lower river (Lewiston area) cannot harvest 25% of the fish, we will obviously allow more harvest upstream; or if a very high percentage of the adults are destined to a certain stream section, we may be required to allow more harvest there to get at these fish. At this point, there is no point for you to worry, just get out there and catch more fish. Now is the time to be fishing the Clearwater River.

As predicted, the first Chinook were caught in the Riggins area last week, but high dirty water slowed things down some. We estimated that only 8 fish were harvested last week in this area. Recent rains will cause flows to increase again; but based on the Flow Prediction Service, the river should peek out on Wed or Thur and then slowly drop. As the river drops, I expect fishing will start getting good, and then 7-14 days later that large surge of fish that went over Lower Granite Dam a few days ago should be getting to the Riggins Area (assuming we don’t have any blowouts). For those of you who like to fish this area, don’t wait until then. Often early in the run there is less fishing effort and the fish tend to be more aggressive which can make for some fun fishing.
We also saw the first harvest of Chinook at Hells Canyon Dam last week. We started collecting some fish at the trap along the Dam which says the fish are there. I fully expect this fishery to take off by this weekend.
I’d like to say I have a bunch of fish stories to report to you, but so far I have just hooked two and landed one. I’m just getting going though. Have fun out there, and stay safe. - Joe DuPont, Clearwater Region Fishery Manager
