"And then I ask myself, why do I rise?"
https://www.youtube.com/watch?v=6rJn7RtWDgU&t=150sGimp, Bob Hunt new the value of wood in the stream as stated at 14:37 of this video, "Abundance of most important trout food item, case building caddis, increased by 70 % in response to greater attachment area provided by increased gravel and wood components in the bank cover.
The area along the stream is grass as shown in the video at 18:26 which probably was harvested by the previous owner for hay. There are no river trees like willow, cottonwood, American elm and silver maple which were probably on the banks before the settlers came to this area.
I'm surprised that Bob Hunt knowing the importance of these river trees next to a stream that provide the food for the health of the invertebrates in the stream that Bob Hunt did not plant some river trees next to this stream.
Wikipedia states that brook trout eat aquatic insects, terrestrial insects, crustaceans, frogs, amphibians, smaller fish, invertebrates and voles. Why didn't Bob Hunt provide habitat for the food that BIG brook trout eat??

P.S. The Frank Hornberg TU Chapter built this same instream habitat structure in this video except we used sand bags instead of rock. We punched 1/8 inch holes into the side so the sand bags so the grass roots could anchor into the sand bags.

These structures work great in a slow gradient stream in the Central Sands but would never work in most Driftless Area streams. Of course with the floods in the Driftless just about every structure can be blown away.
On my home place in Timber Coulee I planted a willow tree in the middle of the stream. The willow tree never came uprooted through many big floods but it collected a lot of debris. My younger brother cut my willow tree experiment down or the willow tree would still be there in the middle of the stream after all the lunker structures and rocks were washed down the stream. (I caught a 22 inch brown trout in a structure built by me from a dead elm next to my willow tree.)

Oh yes, the willow tree in the middle of a stream probably would not look good in a "Milwaukee Canal" landscape.

I wish I knew how to put pictures on this website and I could show you where willows planted by Westby Rod & Gun are still standing straight and strong after the massive flood with tin from my neighbors shed hanging around them up in branches 20 feet above the stream..

Gimp, a bit of advise, get out your heavy gear when fishing by a native river tree because the biggest trout in the stream will be near the most food in and along the native river tree standing tall on the bank of the stream.
