We drifted from Hendricks Bridge (RM 24.1) to Hayden Bridge (RM 14.7) on Friday, and located 17 of the 20 tagged fish. Missing this week were Sonya, Dixie, and Radio. We likely missed Radio near RM 21.0, since he has been ranging around here the past few weeks, and it’s a tough location to track fish due to multiple channels and obstructions. We also suspect that we may have found Sonya near RM 17.2 in a side channel, though we did not get a firm fix on her. None of our fish had moved much since last week. Eeyore was the big mover, dropping out of the hole at RM 22.6 into a section of very fast water at RM 22.3. Others were within 1/10 of a mile of their previous locations. We did find Mike S. for the second week in a row near RM 17.3. A high water event is due for Monday/Tuesday/Wednesday. We’ll see what this does with our fish and fish movement. For now, you can see who is where with Follow Our Fish! ...

Our Friday group of trackers picked up 17 of our 20 fish (again) between Hendricks and Bellinger. The group of fish at RM 21.0 dispersed, with Nigel and Stanley heading upstream about a half mile while Radio remained in place. The remaining 14 fish showed very little movement – at most, 1/10th mile. A second trip took place on Saturday – our first outside the initial release section. We hoped to locate Sonya (released at RM 19.0), Mike S. (released at RM 20.0) and perhaps even Dixie (released at RM 23.2). We found Mike S. in a side channel at approximately RM 17.3, three miles downstream from his release site. You can see on the image above that Mike S. has gone quite a ways relative to our other fish. Since we did not locate him on any previous tracking trips it is likely that he moved down past Bellinger (RM 19.0) nearly immediately after he was released. Follow Our Fish! to track Mike S., as well as the rest of our trout...

Our trackers picked up the same 17 of 20 fish as the previous weekend, though many of them had moved quite a bit. We released 10 fish at river mile 20.0 approximately two weeks ago. Only a single fish remains at this location. Several fish moved quite a bit this week. Radio and Nigel started at river mile (RM) 20.4; and are now at 21.0. Harvey, and Ole headed downstream and are now near the bottom end of our release section at RM 19.2. Gil also moved nearly a mile downstream from his previous location. Stanley was our big mover of the week, moving from RM 19.8 upstream to RM 21.0. Equally notable is the number of fish that haven’t moved much. Nine fish haven’t moved much at all (less than 1/10 mile). Next week we will likely attempt to track fish outside of the initial release section. Suspicion is that Sonya and Mike S. have gone downstream and Dixie has headed upstream. Harvey and Ole are also good bets to move downstream out of the initial release section. See who’s where with Follow Our...

We were able to pinpoint 17 of our 20 fish over the weekend. Stay tuned for more! The fish released at river mile 20.0, including Gil, Lenny, Stanley, Sven, Dasha, Chicago, Harvey, 007, and Ole, have stayed in the general area. Sven is our big traveler of the week – he moved downstream 0.55 mile since 10/17/2012. See who’s where with Follow Our...

Thanks to the efforts of a dedicated group of volunteer anglers and the ODFW staff, we’ve tagged 20 rainbow trout with radio transmitters. The first tag was deployed on October 13th, and the last tag on October 22nd. The trout ranged from 248m (9.8″) to 525mm (20.7″) fork length. The distribution of sizes as shown below should provide an excellent cross-section of age classes. This completes the first step of the Radio Telemetry Pilot Study. Meet the stars of the show at Meet Our...

Thanks to the generosity of the University of Idaho, the Oregon Council of the FFF, The McKenzie Flyfishers, and Trout Unlimited Chapter 678, we are adding a radio telemetry component to the study in October, 2012. Little is known about the seasonal movement of rainbow trout in the McKenzie River. This study will attempt to document the movement of several fish over the course of a calendar year.
