Hi everybody. It looks like people were catching fish about everywhere last week (May 28-June 3, 2012). Hopefully there are a lot of happy anglers out there. For those who like to fish the Clearwater River basin, I have some good news. It appears that survival of migrating adults between Bonneville Dam and McNary Dam was higher than we typically see which has increased our projected harvest share to above 5,000 fish (see table below). The bad news is survival for the Rapid River fish in this same reach appears lower than expected and has resulted in a lower projected harvest share estimate for these fish. These differences in survival are largely based upon when these runs migrated through the fisheries on the Columbia. Rapid River fish came a little earlier this year which made them more susceptible to harvest. The final harvest share estimate will be based on the number of fish that pass over Lower Granite Dam, so these harvest shares could still change some. There was considerable harvest in the Lower Snake River (between Ice Harbor and Lower Granite) so we will have to wait and see how this influences our harvest share.

In the Clearwater Region last week, people were catching fish from the mouth all the way to the South Fork Clearwater River. The only place we didn’t document harvest was in the Lochsa River, although I know they were there. Some of the best catch rates last week were from Cherrylane Bridge to Orofino Bridge, the North Fork, the South Fork, and yesterday I heard fishing was really good in the Kooskia area. There should still be a couple thousand adult Chinook destined for the Clearwater yet to come over Lower Granite so don’t over look the lower Clearwater as well. Finally, I have good news for all of you Clearwater anglers. Because of the higher than expected survival, we will be proposing NO closures this week in the Clearwater River basin. So go find your favorite place and catch some fish. We will look at the harvest numbers next week and get back to you.
Fishing in the lower Salmon River picked up last week which was good to see. Catch rates were not the greatest (20-25 hr/fish), but I certainly talked to some people who limited out over multiple days. I was surprised to see that more fish were not harvested in the Little Salmon River last week; but after I was informed that high flows made the fishing difficult, it made more sense. The rain we had over the last couple days brought flows up considerably in the Salmon and Little Salmon which turned the rivers muddy and has turned off fishing. Based on the flow prediction services, flows should start coming down by Thursday which should mean the fishing will be good this weekend. Obviously, this will depend on what the water conditions are like. Let’s hope it stops raining, as the fish are there and ready to be caught.
We estimated that 71 adult Chinook were harvested below Hells Canyon Dam last week which is considerably less than I thought we would see. We are trapping lots of adult fish at the trap below Hells Canyon which tells me that the fish are there. Some have suggested that fluctuating flows may be playing a role in the lower catch rates. One nice thing about fishing this area is that the water will stay clear and fishable when other areas may blow out, so if you are looking for a place to fish, give it a try.
As a final reminder, there are no plans to close any fisheries or change any limits in the Clearwater Region this week.
Have fun fishing and I’ll talk to you next week. -- Joe DuPont, Clearwater Region Fishery Manager
