Squatch beat me to it...
If true, I’m sure the circumstances surrounding that trib aren’t helping, but Segloch (and many of the other Furnace Hills streams) tend to be pretty silty…sandy actually, because of all the red sandstone in their watershed. As it erodes it basically forms that reddish brown sand that piles up in eddies and on the edges of pools. IMO the floods of 2011 actually helped flush a good bit of that sand out of some of these streams, temporarily at least. Segloch especially so, and I think it’s fished marginally better since. On other area streams, the floods merely rearranged the sand though, and some of those streams (the one Squatch mentioned in particular) have suffered since the floods. It’s still an uphill battle for Segloch though…even if you removed the gravel road that parallels it, and put more of a buffer into the headwater areas, Segloch and its neighboring streams would still be pretty silty/sandy based on their geology.
