Thanks for the electrofishing update Andy! I have a couple questions/clarifications if they won’t be included in part 2 of this post. So if there are a lot of 3-5″ around and it should take 2-3 years to reach your 6-10″ “village idiot” status, the growth rate of these size fish is around 2-3″ a year? Do they do any tagging studies to study that? Also, are their observations of size distribution fairly consistent over the total local watershed (Upper vs. Lower Kinni, Rush, Trimbelle etc.)? Looking forward to part 2! Thanks for the info!

Thank you for the prompt to put more words on the screen.
First and foremost realize my summaries are a combination of scientific data received from the DNR, discussions with DNR personal and my own semi-scientific(heavy on the semi)observations of a variable laden sport called fly fishing. These observations of fly anglers and the trout they long to quarry, coupled with the complexities of calculating Nature, have lead me to believe that to put forth definitives may only hinder an anglers ability to think dynamically. Don’t get me wrong, there are factors when defined, bring clarity and understanding. But overall there is <strong>change</strong>, every day, every hour, every second. When this factor is understood by the angler, it leaves the door open for better interpretations.
My words are derived from spending time with the nature of the riverine environment. I like science and data, and consider them both helpful tools in my attempt to gain answers to questions relating to the quest that is my passion. However, I believe definitives can be crude and fleeting when it comes to the Nature of fly fishing for trout. Change is. Think now. Don’t trip on that rock.

Answers to your questions;
Growth rate-
Difficult to define. Variables crazy. Growth rate, as far as I understand, can vary from river to river, from section to section, from year to year, depending on trout population, flows, ground water, land use, water temps, insect populations and a whole host of other factors. As far as I understand this is only kind of “ball park” estimations. Small fish generally grow faster, large fish grow slower. If my math is tragically off(wouldn’t surprise me), please someone jump in and help me out. To my knowledge there are no tagging studies. Remember Wisconsin DNR has been reasonably handcuffed by our environmentally friendly Governor as to spending money on specific studies like this. Research most likely would come from University studies or individual scientists at this time. Check out google: Wisconsin, trout growth rate, and muddle through the data, see what you find(head spinning).
Observations of size distribution fairly consistent?-
I guess, yes and no. Here are the size categories used in the surveys;
All, YOY, greater than or equal to 7″, 9″, 12″, 14″, 16″, 18″ This remains consistent from year to year. The data I have on the sites sampled is less clear and I don’t want to provide misinformation. The sampler is the only one who knows and I am sure that it is by the scientific book. Mostly I am not clear on all the details of the process
The one thing I do know is that access in some rivers can be the limiting factor. The lower Kinni is a big one where this is access consideration. There is a considerable amount of equipment necessary to do these surveys responsibly. Vehicles, trailers, floatboats, tubs, shockers, generators, bodies are all necessary for the process of collecting data. As you may know, there is little ability to get this equipment down into the canyon. Therefor the center sections of the lower Kinni are not sampled as regularly. Most of the data comes out of the upper Kinni where road and parking lot access make the task possible. Sections on the Lower Kinni that are sampled regularly are the lower Dam and Cty Rd F bridge at the state park. The Rush is an easy mark with all of the easy access points at bridge crossings.
As always, I am open to constructive criticism. No dick head comments

Follow-up comment rss or Leave a TrackbackFool me once…and uh…Great calculamacations and musings Andy. One things for sure…There are some trout that enjoy a tasty mouse now and again on the rush that will surely bend your rod in half!
When it was reported that the flood dramatically reduced the trout population on the lower Kinni I began looking for data on similar occurrences. The closest in proximity that I could find was the Whitewater system in MN and a bunch of studies in the northeast after hurricane episodes. All of that data indicates the populations are normalized after 3-5 years. The Kinni’s trout population had been extremely high for years so just half of that population would be substantial.
Regarding the WI DNR, I recall Marty Engle being quoted earlier this year in one of the Minneapolis newspapers saying the trout population on the Kinni was down but that he doubted that the average fisherman would notice the difference. Does that mean that the average fisherman catches zero to three trout per outing? I am an average fisherman, certainly no expert, and can say that I have absolutely noticed a significant difference.

We are in the same boat. I search for answers when things change as well. Sometimes the answers are too complex to uncover. Sometimes the cause of change is easily defined. Sometimes there is skullduggery. These things do not stop either one of us from searching. The point being definitives! You want them and I respect that. I believe there is some science, some guess work and some unknowns to the population change. There is no real way for us to truly know why things changed. I’m ok with that, but I’ll keep digging. If I learn something, you will see it here.
Richard, or may I call you Dick
I am glad you have had some rod bending action. I hope it continues for you in the future. Try to keep it from going all the way in half, it might break, and that would be painful either way.
Cheers

Thanks Andy for a quick part 2. post and adressing my questions with your expert insight!! You mentioned earlier that the actual electrofishing data for this year would be processed possibly early in 2016? I would still like to get access to it and for previous years now as well if available. If you could post a link or something where we could find it that would be great! You would think that the data would be available to the public (we funded it?!). Tworod, I consider myself in your category as well an average fly fisher at best(on a good day). I also have seen my Spring catch rates plummet recently from 10-30ish an outing in 2013 to zero to maybe one if lucky in 2015?! Science, floods, weird Mojo, whatever, something is going on!

I had crafted a part 3 to your comments. it all went up in a puff of smoke when I hit the wrong button on the magic blog. No time to re-craft right now.
