Slash Loading in Stream Channels

One of the post-fire roadside hazard salvage logging operations was restricted to the existing roadway which made for some challenging yarding.  As a result, a lot of logging slash ended up in the several of the area streams and our foresters wanted to know what to do.  Unfortunately, most of the slash is smaller material and can't easily be yarded.  And we've restricted ourselves to no heavy equipment leaving the roadway.  So we talked about reaching from the roadway, yarding some of the larger material, and even entertained burning some of the slash.  Ultimately, it's just not that big of a deal and my recommendation was to do nothing.  It represents such a small portion of any one stream and having lots of material in the streams isn't a bad thing.  Sure, it'll inhibit vegetation regrowth, but only for a little bit.  The biggest risk we run is having some of the material mobilize downstream and potentially clog a culvert.
You can see how the road corridor was cleared from this angle, but also how a lot of the slash ended up in the ravine

And here is the ravine.  It looks worse than it is.  And a lot of it will get cleaned up since it's close to the road and within the grasp of some heavy equipment.

This was a temporary thing.  These logs were installed above a culvert to catch any debris moving down the stream channel and to protect the culvert from timber being yarded over and across the area
