QUOTE OF THE MONTH
"... it is best to keep those outdoor lights off just in case. That is one way you can help the migration."  Ross Ellet, ABC Meteorologist
 
Greetings from the TCTU Streamkeepers. 
In last month’s newsletter, I shared that I visited with another angler at an area trout stream, TCTU member Gene Scheffler.  He graciously gave me two of his Chuck Caddis flies. 
Well, I had a chance to use the size 16 fly on the SB Whitewater on Saturday, May 2.  Near sunset I decided to give the Chuck Caddis a try and immediately caught four nice sized browns including the largest brown trout of the season so far for me.  The Chuck Caddis worked!  Another angler friend recently gave me some woodchuck fur, so I will be tying some of these soon!  If you don’t have a Chuck Caddis handy, the Mother’s Day Caddis will probably work.
After a long drive to the SB, I encountered numerous other anglers in the area including a family with 3 children.  One of the lads decided to fish very close to me, and what I thought was a splash from a trout turned out to be his large bobber.  He had made a truly amazing cast with a beautiful zebco.  Lots of fun!
Even though the river was "crowded" by my standards, the trout remained very active.  One of the other elderly fishermen that I visited with had been there since 5:00 am when the temperature was a brisk 26 degrees.  The air temp when I arrived was a balmy 60 degrees.

In many Upper Midwest trout watersheds, invasive species management often focuses on well-known culprits like buckthorn or reed canary grass. Yet another plant—wild parsnip (Pastinaca sativa)—is quietly degrading trout stream riparian zones in ways that directly impact habitat quality, water temperature, and restoration success.  While commonly viewed as a roadside nuisance, wild parsnip can have outsized ecological consequences when it establishes along streambanks and floodplains.
Wild parsnip readily forms dense, often monotypic stands that displace native riparian vegetation such as sedges, grasses, and forbs. These native plants typically provide deep, fibrous root systems that stabilize streambanks and support diverse ecological functions.In contrast, parsnip-dominated areas tend to have simpler structure and shallower root systems. The result is reduced bank stability and an increased likelihood of erosion, particularly during high flow events.  For trout streams, this shift matters. As banks destabilize, more sediment enters the channel—setting off a chain reaction of habitat degradation.

How You Can Help
TCTU has expanded its habitat efforts to include taking action on wild parsnips. We have several events either planned or in development, so make sure you check our Events Page to help.

​My wife says I treat trout fishing like a job.  Just about every weekday morning I pack my lunch, load my waders into the car, give her a kiss and tell her the same thing that Black Bill told his wife before catching the state record stream trout on the Whitewater River:  “I’m going out to catch the big one”.  And sometimes I do, although nowhere near the size of Black Bill’s 14 pounder.  Last year may have been my best big-fish year ever.  I caught ten trout in the Driftless area over 16”, including two that were 20”. 
This being fishing, last year's success has inevitably led to this year's failure.  I have been catching plenty of 10-11 inchers, less in the 12-14” range than I usually do, and my biggest fish so far taped out at a measly 15”.  There have been a few opportunities:  I was fishing a bankside pocket on the Kinni in mid April when my nymph stopped.  I set the hook and saw a large head come out of the water.  Then…nothing.  Two weeks ago, I fished a cramped, brushy stream on a tip from Doug Moran.  On the second hole I had a swing and miss from a trout that looked close to 20”.  I reported this to Doug, who went back with his spinning rod and sent me a photo of an 18” brown trout—his personal best.  If I were a bigger person, I’d be happy for Doug.  ​

In 2014, Minnesota passed a riparian buffer law, requiring perennial vegetative buffers of up to 50 feet along lakes, rivers, and streams and buffers of 16.5 feet along ditches.   The objective of this law was to reduce sedimentation and nutrient loading in order to improve aquatic ecosystem health.  
Is the law working?
That is the question that the TCTU Streamkeepers set out to answer last year, by doing macroinvertebrate sampling at two sites on the South Branch of the Whitewater River, following up on research that had been conducted in 2018, shortly after the law's implementation.  A team of amateur entomologists including Mitch Abbett, Carl Nelson, Mark Peerenboom, Jim Sauter and Dave Sauter (aka Jim's brother) collected samples of insects that were analyzed by MNTU Habitat Director Dr. Jennifer Biederman and Winona State PhD Candidate Will Varela.  Doug Moran provided angling support.
