I hope this doesn't go to locksville, but here goes. I hope it is informative.
There has been some discussion about the state of Jordanelle bass [url "http://utahwildlife.net/forum/viewtopic.php?f=1&t=45147#"]fishing[/url] and I figure there may be some interest in this report.
I was invited to help with the fall gillnetting for Jordanelle yesterday. I made some work arrangements and was able to go. Unfortunately I couldn't find my [url "http://utahwildlife.net/forum/viewtopic.php?f=1&t=45147#"]camera[/url] when leaving so no pics, sorry. It was an awesome time. Jordan and the crew were fun to work with and were happy to answer questions. Well worth it and I learned a few things as well.
I won't[url "http://utahwildlife.net/forum/viewtopic.php?f=1&t=45147#"][/url] go over every item discussed, but here are some points that may be of interest to anglers.
1. The main fish pulled out of the nets were chubs. Big chubs and only big chubs. This is in part due to the gillnetting sampling as they are readily picked up at this time of year in the nets. All were quite large except for 1 solitary small one. Is this a problem? The biologist did an otolith study on the chubs last year and found that there hasn't been any significant chub recruitment at Jordanelle for 9 years. All the little ones get munched by perch and bass. Jordanelle will not be overrun by chubs. Chubs can live up to 25 years, but when they eventually die out, there will be a forage problem there. (Per the biologist)
2. We netted a fair number of trout. No super monster browns this time, but we did pick up some nice browns and good sized rainbows. They will plant there in a couple of weeks. The trout appeared to be in good shape. Several small browns showed up, indicating that there will be decent browns in the future.
3. We got a fair number of bass. We did net one nice 18-19 inch smallie, a couple of 15-16 ones, and a fairly large number of 8-12 inchers. Very small smallies showed up with the perch and were abundant. There are plenty of small smallies there. One solitary small LMB showed up.
4. The managing biologist told me that creel studies [url "http://utahwildlife.net/forum/viewtopic.php?f=1&t=45147#"]show[/url] that 24% of the bass harvest was of fish in excess of 12 inches, which is too high with the overall population profile of the lake. He is concerned that this is too high of large fish harvest to maintain Jordanelle as a blue ribbon bass fishery. Not enough harvest of the small bass is taking place. I will let you draw your own conclusions as to how that might affect regulations.
5. The better bass were eating perch minnows, and the small bass were eating zooplankton and minnows. As expected, the [url "http://utahwildlife.net/forum/viewtopic.php?f=1&t=45147#"]rainbow trout[/url] were full of zooplankton.
6. Multiple age classes of perch were netted. They seemed to be OK. We didn't talk about them much.
7. While working, I talked with another biologist about Utah lake. She told me that the walleye population out there is huge and this year and next will be off the charts for eyes if you can catch them. The [url "http://utahwildlife.net/forum/viewtopic.php?f=1&t=45147#"]catfish[/url] are still strong and the white bass are still going strong, although they and the panfish will probably be slowing down with the lower water levels.
Again, thanks to Jordan and the staff for the invite and a great morning on the lake.![[Image: icon_thumb.gif]](http://utahwildlife.net/forum/images/smilies/icon_thumb.gif)
