Thanks for this informative response.
Makes sense there is much less LWD recruitment from upper reaches of the watershed, and hopefully the fresh eggs from the big run this fall have survived the wild flows. We were surprised to find numerous redds along our stretch of river near Willow Creek, and observed a dipper one afternoon before the main storm moved in, munching what we are pretty sure were fish eggs. Turns out that is a favored diet with dippers.

One year, the flows and accompanying LWD left only dangling ropes and cables where a 8' rotary screw trap was once stationed. Huge trees were blasting through every few minutes. Those trap's pontoons almost rode out the New River gorge, but settled up-rite, on top of some house sized boulders. What a ride that must of been. The screw portion of the trap was totally "screwed." We had the parts flown out when the flows subsided.
> I remember LWD naturally being stored in the New River bank full and floodplain, all the way up the drainage, and mobilized during these kind of peak flow events. Many had chainsawed ends. I assume they must settle out somewhere in the plains or ocean below. Unlike below the dam, the LWD, sediment, etc. are naturally replaced from the many plains above. I would expect that the SF, New, NF, and other large tribs, along with the mainstem Trinity above, were pumping out the large amounts LWD that you all saw.

> Watching the Trinity from our spot between Camp Kimtu and the mouth of Willow Creek, I am amazed not only by the volume and velocity of the river today, but by the amount of logs and debris coming down the river ... I haven't seen this many logs in the river since the 70's.... maybe not even then. It has been a constant stream of all sizes of debris, all day. They look like schools of sharks and sea serpents floating down the currents. Neighbors sitting out on benches today say it's been like watching a parade.
