I was about to post pictures but I see Sugartooth beat me to it. I walked past the fresh debris flow at the clay banks on Saturday morning. I'm a geoscientist so I find this stuff pretty neato. Excavating the material from the fresh debris flow and trucking it out would make space behind the dyke to impound future debris flows providing they are small. I'm very curious to see how this pans out. Here is a link I found detailing the works project: http://www.dfo-mpo.gc.ca/library/282335.pdf
I have this vid link on the Slesse Slide on Fishing Related Issues and News but thought I would take the liberty of posting it here as some of you may not go there. Thought the history of this slide is interesting, at least it held up for 19 years and made better water conditions for that time and kept some silt and clay out of the river bed.
"I have been going through my hundreds of old VHS tapes and more recent DVD's. I am putting up some on my u Tube channel.
Here is one I produced nearly 19 years ago for the Chilliwack River Action Committee using some of my footage, also other film I dug up, footage provided by BC TV, script I and Fred Helmer Jr. wrote with voice over by Scott Riley as well as Grant Ullyott from the former CHWK radio station in Chiliiwack. I am sure some of you will recognize some people in the video.
It is sort of fitting at this time as the clay slides may be a problem again after the high water events this year. Hope you enjoy it, I even caught a steelhead just below the Hydro Bridge, the second one at the start of the video.
